Hi Folks..
been machining for a while with a roland mdx-15... outgrew that in about 3 months and moved on up to a Minitech minimill2..
I have only just finished setting her up about a month back and am now selling them in Australia for Jack.. made my first Sale/delivery/tram last week.
i love mach because it gives me control over my machine.. im looking at ways to jog more precisely than my keyboard will allow me and looking at using a gamepad or other analog device to make tiny incremental steps possible for "tip to tip" alignment in various passes.. no idea how to do this yet.. but im sharp.. i will figure it out :)
anyway here are some pics of my rig and some of my work off her.. she has been named Gertrude!
[edit] no worries on external controller setup.. use search function Mr.Botha.. doh!

and more.. 4 pics per post???
-
et al
-
cut these on a customers mill I installed and trammed this week...3 sided cut and i think its pretty well trammed :) (Z is a touch off in flip cuts resulting in feint +-15 micron ledge in lower image.... i will live with it ;) )
-
Beautiful work there Chris....and a foxy little machine too !
Thanks for sharing with us.
Regards,
RC
-
Brilliant work there Chris - I agree, you certainly are sharp. :)
Tweakie.
-
Wow. Great stuff. It looks like you've really spent allot of time and effort on those, and they look superb. Thanks for sharing the photos.
-
Incredible work, Chris, thanks for sharing.
Do you use artcam? Do you have a website?
Thanks,
Dave
-
Very, very good Chris! A good looking machine and good looking parts your making with it. :) :) :)
Thanks for sharing,
Brett
-
Good design fancy works very well done
Marcel Beaudry
-
thanks guys.. i have only been machining for just under a year now and only for a month with a decent mill, i could not achieve that kind of accuracy with my roland.
http://www.digital-jeweller.com/ is my website and no i dont use artcam i use Rhino primarily :)
-
here is Gertrude getting some on youtube!
cutting a Celtic Knot ring as pictured below
http://www.youtube.com/watch?v=2aikPg7wDrQ (http://www.youtube.com/watch?v=2aikPg7wDrQ)
hope that works :)
will try post images/vid of finished ring when it off her soon
-
urgh.............
somedays....
http://www.youtube.com/watch?v=L8J8knrsGgs (http://www.youtube.com/watch?v=L8J8knrsGgs)
looks good??? sure does.. cut perfectly.. pity bout the air bubble in the wax which is now a hole in my surface... look out for a nice round hole in the vid...
the best laid plans of man and mouse.....
cut again!
-
Spotted the bubble Chris - I am sure you could blob a bit of wax in there and with your skills smooth it off again.
Tweakie.
-
yeap.. i can.. and likely will..
still bites my ass tho!!! if i had seen it before i hooked it off the mill i could have rolled mach back to that point, blobbed wax into hole and simply recut that section.. once its off tho there is just no way to realign X..
but doesn't happen often.. got some waxes back from casting today and here some shots of finished work.
-
Excellent my friend. Superb work.
Tweakie.
-
ok had a go at wax repair.. im still 50/50 on it.. but reckon will clean up ok with an engraver post casting...
-
oh yeah by the way.. i did a series of tut's on jewellery design in rhino a while back, the free version available here for anyone interested.
http://3dcadjewelry.com/tuts/chris/ (http://3dcadjewelry.com/tuts/chris/)
have a good day guys :)
-
Very impressive Chris.
Brett
-
Dang dialup...
I couldn't survive without tutorials and would really like to see these.
So....I'll just have to wait till they get our phone lines off of the farmers fences and up on poles where they will work better.
RC
-
thanks guys.. nothing special.. really basic stuff.. I feel our trade (jewellery) is too closed and anything related to it is kept carefully guarded to ensure that better margin over our competition.. to the point where we are wiping ourselves out as an artisan trade.. so I try be as verbose as I can and share as much knowledge as I possibly can hoping others hitting the same headaches i do have something to reference. (albeit my method be right or wrong ;) )
my upload speed is 15kb/s .. that took me ages to upload so dont feel bad bout your dial up lol
-
Those of us that are eager to learn are very fortunate to have folks like yourself that are willing to share their knowledge and experiences.
You (as well as others here) are to be commended and I for one condone your "method".
Thanks Chris,
RC
-
Chris,
Just checked this post , and I must say , SUPER FINE , work your doing there.
Also checked your web page and the videos. I'm impressed at your crafsmanship.
But when older age comes along and the eyes get weaker, you'll probably switch from rings to braclets, ;D
Nice bathrobe , BTW. ;)
Thanks for sharing, and don't stop.
Ed
-
"when older age comes along" ????
dude.. its arrived...
hey.. anyone able to identify that lathe i bought off my watchmaker mate in the video I posted? I think it needs to be adjusted.. the part that holds the tools and slides along "x?" is wobbly.. like its been worn or something.. i see a row of hex bolts along its side and i think they are meant for adjusting the tightness of the slide..
man.. as im reading this even I cant make sense of it.. no matter will post images tonight...
-
Chris,
Just curious. What was the cycle time on the Celtic Knot milling...excluding the bore.
I sometimes hit 30kbps so I should feel fortunate huh. lol
Thanks
-
hmm 2hrs I guess.. lemme check path info.
the fingerhole i do before the time on the lathe.. about 5 minutes.. hook the wax onto the conical clamps that are in the video then remount on lathe to machine the outside down to just outside my required stock thickness.
ok this just in.. 1h45min for path itself so maybe 2hrs machining all up.. path at 600mm/min 0.015mm stepover with a 0.127mm cutter
(plus 10min for filling in damn bubble void.)
added 3dm for kicks!
-
ok heres that lathe issue. this time with pics!
see image with red line and arrows.. that part of lathe "wiggles" and tho i dont cut anything tougher than wax with this i still reckon i need to adjust something.. i think its loose on its guide. and the image after that shows the only adjustment i can see.. a series of little nuts n bolts...
im guessing i tighten those till wiggle goes away?
also while im on it.. i can pick up 4 axis kit with BOB , 1.8' steppers etc for 250USD.. now thats pretty croddy equipment im sure (right off ebay too) but would that be hard to rig that upto this lathe? is it worth doing this as a side project? (not that i need anymore side projects mind you)
-
Hi Chris,
I use cheap (made in China) stepper controllers without any problem on small machines the only drawback is that most of them have 2.5 Amp max. rated drivers and would not be suitable for driving large steppers as would be required for a big machine. I think it would be a worthwhile project to convert the lathe if you have sufficient spare time and the lady boss approves.
Tweakie.
-
the lady boss... yeah there is that factor too....
thanks for info :)
-
im guessing i tighten those till wiggle goes away?
Chris, yes, you loosen the hex nuts just a little and then tighten up the slotted set screws which should be tightening up against a "gib" that then presses onto the dovetail. Tighten up each screw slowly along the full travel ( I like to go one at a time to see where each screw is tightening up) and then once you have it in a good setup, the hexnuts get tightened up as well and that should lock the setscrews in place.
Unfortunately sometimes it's a trial and error game as the set screws sometimes tighten up against the gib and mess up your final setup so you have to back off and try again.
You may want to actually pull it off first to make sure there's no swarf or dirt in there to damage the ways.
Hope that helps-
Dave
-
thanks man!
gonna give it a bash tonight
-
Do you ever get any sleep ? ;D
Tweakie.
-
sleep??
oh yeah that... i catch naps in front of my pc right after i shower ;)
-
hmm megapost again..
in case you interested to see how i go about 3 sided and why im after button macros.. you can see the "holes" and "pins" in this.. pictures follow logically.
-
,,
-
...
-
never got to the damn lathe.. tommorow night...
-
Quite amazing - I wondered how you did it. Keep up the postings I am learning so much.
Tweakie.
-
that job cleaned up and with its stone...
will post done deal after its cast
-
Beautiful work, Chris, is that an Amethyst?
So now the next step for you is to send this out to a shop that will cast this for you? How does that operation work? What material have you chosen for this creation? How long does something like that take to be processed for you?
Needless to say I've always been interested in jewelry making but never dove in - :)
Thanks for sharing,
Dave
-
that goes to our caster now, this particular job is being cast in 9ct white and will be back on my bench in about a week and then I polish and set.
-
Nice, can't wait to see it finished-
Dave
-
oops oh yeah .. an amethyst.. i hardly get to work with semi precious.. so its nice for a change :)
-
It's a nice looking one, it's my wifes birthstone and she loves it and needless to say she has a few pieces to prove it ;)
It would be nice someday to actually make her some jewelry rather than buy it-
Dave
-
mine as well.. but she hates jewellery.. which is why i married her :)
hang ten let me get some photographs of stuff ive made for her that she never wears...
brb
-
..
Sphene pendant for her Bday.. she hates it..
-
photo of the kids milled and cast.. this one she wears sometimes
-
latest one.. my "puzzle pieces".. this one im not sure.. not seen her wearing it yet (webcam pic.. urghh)
basically she just wears her engagement ring and wedder...
-
You certainly make some beautiful stuff Chris.
Tweakie.
-
thanks man :)
Gertrude be getting her some bangle action today.. not doen yet but looking good so far!
First bangle ive ever tried so hope it comes good ;)
-
Just curious Chris, but is Gertrude the name of your machine ?
Tweakie.
-
hehe yup she is Gertrude. my Roland is Millie, short for Millicent :)
-
oh and the lathe is Margaret :)
-
Right - now it all makes sense. :)
Tweakie.
-
woooooooohooooooooo 4 hours later!!
-
bit of good ol fashioned hand work to remove hub and clean up hinge and she is ready to cast :)
-
Chris,
How and where do you now attach the sprue to pour the casting now that the hub has been removed ?.
Tweakie
-
2 AM.. cant sleep :)
That job has been cast ans assembled already.. i dont cast myself, it goes to a casting company, they attach a sprue dependant to where it will placed on their tree of castings and according th emethod which will give them best flow of metal at the time.
i will upload images oc complete stuff from work in a few hours and hgilight where the sprue was
-
Thanks Chris - I can tell that it is 2 am. ;D
Tweakie.
-
ok 6AM .. wow look at those typos!!!!
hehehe
will post info in a bit.. time for daily 1 hr commute in Melbourne traffic!
-
ok.. amazing what coffee can do for the body...
i got this back from the casters yesterday and assembled. the stones to be set are done off site as well.. diamonds i usually set myself.. this hodgepodge of semiprecious stuff i wont touch...
was sprue'd from inside in two halfs of course as per arrows.
-
..
-
got these back .. on my plate for today.. let me get stuck into it.
-
Great stuff, Chris, thanks for sharing these great pics.
Now for my next question, you can just say "none of your Damn business", but may I ask what something like the gold setting cost to have cast, including material?
Thanks,
Dave
-
Chris, Those are beautiful. Great work..................... sure glad you found the forum. :)
Brett
-
thanks guys...
i charge design time at $30AU p/h and machine time at $35AU p/h, so from my side the cost on that gold 8 claw job would be about $160AU to the trade then the metal costs $29AU per gram and weighs in at about 7 grammes so $203AU plus about $10AU casting fee...
all up for my employer this works out to about $373AU COST.. i add a slice for myself where i can, if i can.. depends on each job at its own merit.. some rings like that 8 claw actually only take about 5 minutes to design and jobs like the bangle for example took 2 hours to design.
what you loose on the roundabout you find at the swings...
-
buggered if i know what exchange rate is today from AU to US lol
-
this one just finished.. easy to clean up.. very simple job.
-
these just finished :)
-
Very nice stuff Chris. Great pics, too. Thanks a bunch for keeping us entertained! I wonder what tomorrow will bring. ;D
-
thansk guys.. always more jewllery.. .. im a little tired of it actually.. want to broaden my cad cam into other areas... woodworking seems nice...
-
Simply awesome, Chris, thanks for that. :)
How do you handle the stamping inside the ring?
Dave
-
at the moment i actually physically stamp it. but with carefull pathing strategies you can cut inside too if you are doing hybrid 3 sided cutting.. ive not bothered so far.. too much mission for something that takes 1 second with a hallmarking stamp
-
or you can do it easily with a 5th axis ;) i really want to add one but pathing software makes this prohibitive :(
-
You have just gotta get more sleep buddy.
Tweakie.
-
lol
-
last nights job.. 3 carat tanzanite surround by diamonds..
cut came good..
-
done and dusted!
-
and this
-
not entirely sure about this job.. i suspect might be nipple caps of some sort.. on the mill tonight...
edit added WIP pic.. gotta love a ball endmill.. see that surface shine.. and lord alone knows why i have that Z ledge...
always does that on big cut transfers.. think my Z is funky...
-
i need to retram :(
not often i cut long sections like this but there is a distinct thickness error on the far side.. at least 30 micron..
man i hate jewellery...
-
No you don't - you just love it !
Tweakie.
-
hehehe .. yeah ok i do..
did i say 30 micron. my bad i meant 300 micron.. look at thickness of wire on falr left and far right on top picture to see whaqt i mean grrrrrrrrrrrrrrrr
-
more signet action.. havea few other pieces to mill for this COA's
-
have to knock off this ring.. bigger, thicker etc..
-
step one done, head on mill now.
-
first attempt at head was a failure!
bad designing..
back to the drawing board...
-
this is better.. texture more apparent and generally crisper.. went down to 0.076mm cutter
-
0.076 mm Cutter?????????? One of my hairs is 0.05mm.
-
lol yeah i think you yanks call it a 0.003thal cutter
http://www.bitsbits.net/index.php?main_page=product_info&cPath=17&products_id=19
:)
-
think they go down as far as 0.001thal or 0.025mm
-
this one also with 0.076mm cutter
fresh of the mill.. man busy Sunday... time for a beer and a bbq!
-
and this is what you look like after too much milling....
-
....or too much red wine. Been there, done that! >:D But, if your still able to take a pic of yourself and post it, you've definitely got a long way to go till you get there. ;)
yeah i think you yanks call it a 0.003thal cutter
it's 'thou', short for 'thousand/thousandth.
-
the wine is for medicinal purposes... that's my story and im sticking to it!
thou!! thats the one.. err while we on the topic.. since the motherland is also decimal.. don't you guys thinks its about time you joined the rest of the world in a numerical system that makes sense????
-
We're still evolving........ priorities first - ;)
Dave
-
heheheheh.. always catches me when im buying bits.. i see a profile 0.010 and think "wow at last a 10 MICRON CUTTER"...... then i see its in inches....
-
My Dad told me about Inches - they are best to be avoided.
Tweakie.
-
my dad told me to be a plumber or something.... i picked "or something..."
got two more of those damn pointer dog thingos on mill tonight. neighbor will be livid again...
-
done and dusted with 20 minutes to spare before my neighbor can officially lay a noise complaint!
-
Helo Chris
Groetnis van a mede Suid Afrikaner. Toe ek jou naam sien het ek gewonder maar toe ek jou video sien met die drie kleur teen die muur het ek geweet......
Baie goeie werk. My vrou se dit is jammer jy is nie meer hier in SA nie. Jou werk het reedshaar hart gesteel.
Hou so aan.
Deon
Port Elizabeth.
-
Dankie Man.. ek is ok van Port Elizabeth af .. ek he vir Francarlo Juweliers gewerk daar!
-
either nipple caps or tassle drop earrings.. i like multi functional jewelery...
-
hot off gertrude...
icky job this.. hard to path and cut and assemble....
-
what its hopefully going to look like
-
Beautiful.
Tweakie.
-
thanks man :)
hate these jobs.. its hard enough to just get one Flip+Rotary job to line up but to get three of them all to line up to each other is pushing the edges a bit.. giving me grey hair.. very almost sent this one to printing.. decided i had not self flagellated enough this week..
off sick today with stiff neck.. apparently one must not chew the viagra.. just swallow...
-
Why am I not surprised about the stiff neck ?.
Tweakie.
-
ohhhhhhhhh .. good point!
i forgot bout that!
-
been slow today.. this one is WIP...
-
Gertrude gettin some probe action...
http://www.youtube.com/watch?v=6SFxLRWyyL4
-
gertrude did well. 1140mm/min at 6.8mm plunge.. thank goodness i only cut wax!
its a box clasp assembly for a triple tennis bracelet..
big job.. loads of moolah.. nice to see people spending again.
heres raw video of promo material i am compiling.. decided im no George Clooney so i dont feature in it :)
http://www.youtube.com/watch?v=HN3eGzTBYFU
-
Hi Chris,
I really don't know where you get the time to keep doing all this work - haven't you got any hobbies ? ;D
Tweakie.
-
lol.. ok youtube pulled my vid.. here is direct link to wmv
http://3dcadjewelry.com/tuts/chris/Minitech%20Getting%20Some.wmv
-
Just Finished :)
-
this one ready for setting.. went together like it was planned or something...
-
Just awesome Chris........incredible looking pieces you're making.
The video was great too, thanks for sharing that as well-
Dave
-
Thanks man.. I am going to be be making about another 10 hours or so of vids detailing all the different aspects of milling jewelery in laymans terms to keep on my website for customers and general consumption. that was a precursor.. hopefully my directors skills will improve..
On a side note.. and i have asked ths same question in other quarters.. im getting tired of jewelery.. but i cant figure out what else to do that will include cad and cam and my handskills in another industry that will pay better? I earn way under what guys around me in other trades are (with far less skills than me (not being facetious)) are and i am not getting any younger... at 37 if i want to trade hop the time is now..
any suggestions? job offers? random million dollar donations to my cause?
-
Hi Chris,
I don't think that anybody who works in a 'hands on trade' by using their skills really earns any money. I know quite a few skilled craftsmen from various ,apprenticeship backed, trades and they just earn average money (and work hard for it).
The way to go is to provide a service rather than a product and just use your skills for private and personal jobs. I know a few rich people and none of them physically produce a product in their work. They perhaps don't sleep too well at night but they don't seem to me to be working very hard for their money.
It's sad but true.
Tweakie.
-
So .. you saying i need to start producing sex toys on my mill?
seriously tho i think you are right.. and you not the first person to say that to me.
-
I would GUESS that there is a unique market for your skills as a service provider. They summit a design and you convert it into working code and send it back machine ready to run . It could be a provider for any profession that requires unique design conversion and converting that into machine code. That way THEY save all the trouble of the conversion WORK and then take the machine ready code and PRODUCE their product.
YOu will have to do some leg work but as the work is starting to come back onshore your services could be a BIG deal to them. Saves them from having to hire permanent help.
YOu would be a subcontractor
YOu woul d never have to leave home. Just work out a dependable way to GET PAYED before they recieve their goods. Money transfers work real well> JUst let the local police KNOW that you deal in money transfers as an everday thing OR you may get targeted as a Criminal type
Just a thought
-
i have considered subbing to my current employer and then to other jewellers too.. suppose im just nervous to do this for myself... but no one made money working for a boss.. think its jsut a matter of time...
-
been a while. had a few things on but back at grindstone. nice job for a ruby and Alexander the Great ancient coin.
-
Just a suggestion, but it may be worth scanning the image of the coin whilst you have it in your hands. May make a future project one day.
Tweakie.
-
i have nothing that can scan that fine. been playing with david laser scanner but thats not really much good at anything smaller than 6 inches or so.
-
Make a casting of it while you have it.
-
i would attepmt to touch probe and/or laser scan and mill purely for the technical hell of it. vulcanizing it would just be plain out right naughty ;)
-
got this baby on today. Clockwork. nice to have a dependable mill...
-
some more stuff from this week.. one head.. then a remake after i read the packet properly.
and a 7 stone eternity ring, 3 sided
-
coin job back n finished. looks ok
-
three heart ring from a mate's design. hmm a 3 sided 3 heart ring.. i like it!
-
wife been having a go at pathing and milling. doing nice job too. she like mach.
-
Very nice work Chris. The avatar isn't bad either. LOL
Brett
-
hehehe thanks :)
-
think i should try mill this sucker?
3dm attatched :o :o :o
-
Chris, that looks like it would be done in segments and then assembled, no?
Neat design :)
Dave
-
lol yeah. not really going to do it .. its a dodecahedron frabjous thingy. math art stuff.
http://www.evilmadscientist.com/article.php/frabjous
-
she cancelled this job... after it was cast...
and heres something off the mill from yesterday.
-
and this one.
interesting one this, some 2 sided in the trillions, 3 sided in the shank, and 5 sided plug cutting for the head.
cut the trillions with the flip portion of the shank and separated out.
the 5 sided plug method was nice, i love the accuracy of my mill and the ease that mach gives me for controlling Z and X with offsets.
all the parts are keyed to lock into each other after casting, see last image for the keys in the shank to take the trillion settings etc
-
Sods law on things going wrong.. if it can it will.
heres a little photo pictorial on how NOT to do a plug 5 sided cut...
and yes.. that is PlayDough jammed in there to stabilize the piece after i realized there was not enough support...
-
..
-
but she did come good..
::) ::)
-
few more from today..
-
another multisided monstrosity..
-
here is the code for that . 15 degree 0.127mm conical flat cutter.
this was generated by the trial version of deskproto. still playing around with it. looks nice.
-
NAKO.. Not Another Knock Off!!
This is a knockof fof job in a magazine. pretty rough pathing but its to see size etc. think final one will have texturing possibly.
;D ;D ;D
-
only got to see these today. milled them quite some time back.
-
Aahh the pointer doggy again. Nice work Chris.
Tweakie.
-
here is something a little bit different..
from the cast to finished in logical order
-
..
-
Absolutely sick, my friend, just fantastic work. I can not thank you enough for sharing these, just stunning.
Can we see a final pic of the last one with the stone mounted?
Thanks,
Dave
-
yup will do. will be next week some time
:)
-
some back from setting and others out on their way.
im enjoying my mill.. makes life jsut that bit easier.
-
first time i ever cut metal... my nerves were shot.. even tho its only aluminum..
hogged out bulk on my lathe then wrote rest of path to trin and cut concentrically to my own mill. i made a startling discovery.. metal is not wax.. its noisy and its messy...
oh yeah its a new idea for a key for myself for flip+rotary parts.
-
this back in.
-
Neat, Chris, what's the black material for wearing around the neck made of/called?
Dave
-
neoprene :)
-
Chris, you do some great work. :)
Brett
-
been making more fixtures... this one locks up a model after three sided cutting so i can cut away the inner supports.
(note: the hub id off centre.. i screwed up the path but i think you get the idea.)
i tried to use the cut circle wizard in Mach but it seems locked to IPM and inches for size not mm, even tho my mach is set to use mm. ??
i put in 50 as a plunge unit and it shot down to my model at super speed, so im guessing its 50 IPM not 50mm/min? i have no way to tell from the wizard what the units are.
ended up coding a circle cut so i can trust it.
-
center of the hub is set as offset in mach.
-
*cough* :-[ :-[ :-[ :-[
someone noticed my hub was off center.. yup i blew it, i forgot to probe the tool that cuts the keyhole and its shanks moved my wax .. thought i could get away with it.. but fellow jewelelrs eyes are too sharp.
recut the job.
::) ::) ::)
if ya gonna do it.. do it right i suppose!
-
this is the code i used to cutoff the ring ..
G00 Z10.0000
X0.0000 Y6.8000
G01 Z-5.000 F150.0
G17
G03 Y-6.8000 I0.0000 J0.0000
Y6.8000 I0.0000 J0.0000
G00 Z50.0000
G00 Y0.0000
M05
M30
now it occurs to me this should be reasonably simple to setup in mach as a macro that will popup a dialog box and ask me for Green = ((Fingersize/2)-(Cutter Radius)) and Red = (Depth below Z0) then run that code?
-
another one...
-
here ya go budman.. she came back. looks stunning.
-
Indeed it does and thanks for sharing, Chris.
My wife would lose that setting in a heartbeat. :D
Dave
-
At $110 000 I bet she would'nt!
or..
she may be refered to as your late wife.. ;)
-
:D
-
few more finished..
this one got lost and eventually found its way back to me.
-
this was initially printed because i didnt like the angles involved.. the "thing" that arrived back post casting was not worth even removing from its packet.. i did the job properly on the mill..
lesson learned..
nice ring.. 1.74 ct stone with some mellee..
-
You certainly have a lot of skills there Chris.
Tweakie.
-
thanks man. i did this photo montage to show how work was done precad.. lol.. the good old days.. i had to make this by hand yesterday because of the time factor involved.
this of course has nothing to do with mach or mills but figred would be interesting none the less as a comparative look at the production process...
-
this was a bit of fun.. i tested a new fixture from Finland... no preperational moves.. just trusted mach fixture offsets to work right.
how can we get around the filename issue on the forum, we all own digital cameras so everytiem i post from my camera someone else has already posted with that image name requiring me to repost from scratch after renaming my files?
-
Chris, slow down a bit, chill, you are just way too productive. Remember 'supply and demand' or you will flood the market and prices will fall. ;D
Tweakie.
-
heheh that one was for testing only.. want it? i can post, but it'll cost you.. 100% pure wax i tell you....
-
here is a video of the last bit of a cut i just did, sam eflip fixture as before, bit of mach action in there, figured would share here too.. very low quality, sorry :)

Great Video Chris, I still feel quite dizzy. ;D
btw. The Boss doesn't smile very much does she ?. ;D

-
I would love to see your face in one of your video, just to be sure it is not the one we see in your avatar. ;D ;D ;D ;D ;D ;D
Great video, thanks to post it.

Great Video Chris, I still feel quite dizzy. ;D

hehehhe
not at me anyhow.. dont think gettin her out in the mill room at 8pm on our wedding aniversary endeared me to her much!

another three sided one, fresh off Gertrude..
-
been a bit since i posted here, been pretty busy actually.. this one was a bit different to do.. challenge was to cut it with hollows to bring weight down as its to be cast in platinum... even a 5th axis would have struggled with this so öut of the box"time
1: cut flips as per usual, add some caps
2: run rotary path over hollowing areas to cut through solid heart sections
3: use caps to plug holes only 1mm deep from top, melt into place with wax pen
4: run full rotary path
5: drink beer.. kick dog.. shout at kids.. fart..
(dusted gold to photograph better)
-
see previous post for explanation

Hope that's just spray paint Chris and not real gold. ;D

lol. no artists ocre dust.. atomised copper i think?

a pendant.. i think?

and a ring.. fancy that, me posting a ring....

Avatar - looks like you had a 'bad hair day' Chris.
Work looks superb though.
Tweakie.
-
my wife FORCED me to have a haircut lol!
-
it was a double dare!
-
ITS BLOODY AWESOME!!!!!!!!!!!!
i am showing my wife and kids and yeah, my boy wants to know why i am not getting him one.
-
hehehe, mine is not interested at all in the wax one.. he wants it in metal.. little bugger, maybe i'll mill one in acrylic for him and spray paint it ;)
-
@ Tweakie..
better hairdo?
(its been rumoured that i am not really photogenic...)
-
believe it because it is troo :)
-
an i thort wuz handsome!
-
OK Chris - That is better and it looks like the repair job has been done quite professionally.
Incidentally the difference between a good haircut and a bad haircut is about four days.

WHERE IS GERTRUDE ?????????????????????????????

I have been laying low guys. some freak who never got enough love from his mother has targetted me and is causing significant grief for me. I suspect its a software or hardware manufacturer I upset. I review many products and own quite a few, my hard hitting reviews/comments/observations on other forums about these products may cause loss of revenue to said products/packages and my comments are not always be well accepted. This person has intruded for the second (possibly third) time into my private life now and risked me my paying job.
I am restraining my posts to Facebook page as the ip's and user details are logged and traceable by me. If I discontinue posting and my threads still recieve significant reads on other forums by a small group of selected reader this will be an easy way to see which freak is checking out if im still posting.
The biggest problem with sticking your neck out on the web is that every so often it will get chopped.
feel free to follow posts on facebook page if you like. I will continue to post here but keep it limited to tech support/help issues. I will resume posting normally after we have tracked this idot down.
-
Chris... that is just wrong.
If someone cant take your opinion, they are weak.
Or...
"ons stuur die manne oor, en breuk sy fingers"
translation "We go over and ask him to stop harassing you, in a nice way"
-
Thats a sad story Chris.
In the UK there are Politicians and High Ranking Officials who have lost their jobs or credibility because of FaceBook postings which have been taken out of context by small minded individuals.
Stick with the Mach forum Chris where we are all adults (except me of course).
Tweakie.

:)
This is an open forum with threads being completely transparent so i never post harder punches here anyhow, but on my "closed" forums i dont hold back. this means that members in those forums are able to take bits and pieces of threads and send them onto other people completely out of context. In this manner I was made to look like , and i quote " a white supremist master race clan leader" out to kill all "hispanics and blacks". this info was sent to a person known to be unstable at the best of times with the indication that it was my intention to do him harm. He then called all my suppliers in the USA besmirching my name. The first i ever heard of it was when my suppliers started calling me.
After this my local council recieved an anonymous tip that I run a sweat shop from my garage, with at least 5 to 8 permanent staff and a barrage of heavy industrial equipment that runs 24/7. my staff and customers vehicles apparently blocking access to my entire street with "strange" people fetching and receiving "certain illicit goods" from my home in the middle of the night. etc etc . the council investigated and of course the council lady laughed once she saw my HUGE mill.. not to mention the fact that my wife must be superwoman to prduce the goods of 8 labourers
Just recently this person has taken excerpts from my posts on a forum regarding my sciatica and has claimed that i am about claim workcover and blame my boss for my sciatica. which both my boss and i know is largely been affected by the trauma/stress of my mothers murder a little while back. All the members on that forum know of this too. this person posted said information in an anonymous letter to my employer and put my job in jeopardy.
so rather than give this obviously unstable sack of swine intestines any more ammunition I am retracting from private forums and not posting anything other than tech support issues on others.
-
Good advice Chris.
A lesson to us all is to take care what we post and where we post it.

my problem seems to have resolved itself. been a while since i posted. figured id throw this one in as its more interesting than my usual drivel.

Hi Chris,
Haven't seen you for awhile (haven't been online as much myself either), glad everything is cool with you and good to see you back.
Beautiful work as always, and always appreciate the pics.
Thanks,

Thanks Guys. I decided that hiding out from the assjockeys of this world was only giving them the power they crave. I welcome his return and my efforts with APF to put his dumbass in jail. I now record all electronic communications etc. his ass is grass if he tries me.
back on track. i decided to oxidise the bell instead. will post image later from work.

not been much on my plate lately so I decided to mill this rather than grow it.. turned up ok...

So you finish a cut, super fine job, and admire your almost non existent supports... (as an idea of scale the hole in the settings is 5.2mm and the surrounding prongs are only 0.3mm each)
(http://lh6.ggpht.com/_E5AvLF8D7WU/S47JC8tsvcI/AAAAAAAACEw/JAmSfEXhLng/s800/IMG_1456.JPG)

THEN.. you turn the wax around and find this!
Metal shavings from my lathe got into the remelt!!! (hoping its AL)

NOT GOOD! Cutters no likey metal metal.. dey go breaky breaky.. I got lucky this time..
time to inspect the rest of my remelt stock..
-
Close call there Chris.
Reminds me of an a**hole TIG welder where I once worked.
There were aluminum weldments that needed some of the fillet welds machined.
This guy would bury little chunks of the carbide electrode in the fillets just to pi** off the machinists.
He didn't last long.
Did you get the rocks set in that GecFrog yet ?
Anxious to see it.
Thanks
-
GecFrog went directly from the setter to the client (overdue), I never saw it finished either :(
-
ooops, :o ...... and those little cutters, when they go breaky breaky, are awefully quiet and sneaky when they do so ;)
Dave
-
Still you have to look at it this way - the cutters from China are cheapy cheapy and the more you break the more mouths you feed. Its called doing your small bit for the emerging nations. ;D
Tweakie.
-
That's one way of looking at it I guess. 8) The cutters might be cheap, but all the wax I've seen, is pretty pricey. How much did you contaminate Chris? Any way to get it separated? Maybe heat it up really hot and let the heavy stuff settle? Small screen?
-
lol.
after i did this i posted on 3dcadjewelery too and a very important bit of information came to light.. metal is heavier than wax, so only the very bottom of the remelt will be affected, so new system in place. melt once, shave bottom off, remelt again!

mirror of a post on 3dcad forum about when arcfitting will bite your ass...
well.. blow me down.. I learned something today.. arc fitting can sometimes work against you!
on low gradual surfaces the arc fitted code resulted in a VERY stripey cut, and i was waaaaaaaay dissapointed.. I had to recut anyhow as the wax came out to thin, on the next cut i forgot to ARC fit my code and the resultant cut was infinitely better.. it did show some stl facetting.. very minor tho in comparison to the distinct striping from the arcfitted code.
SAME STEPOVER, SAME TOOL, SAME STRATEGY, SAME SPEED.. only difference was the arcfitting.
ARCFITTED PATH

-
Hey Chris,
Could you explain this a little more please. I am baffled.
It looks like the top photo has the toolpath running horizontal wheras the other photos look like the toolpath is vertical to the piece.
Surely if the stepover was the same then all phots would show the lines, wouldn't they ?.
Tweakie.
-
the first cut was arcfitted, and the resulting arc was drawn over a perfectly spherical shape.. IE: one arc from left to right.. the bottom path was left as a sequence of XZ,XZ,XZ,XZ etc etc then one Y movement at each end. I have never had this happen before and i think the reason is exactly that the arc travels the complete distance of the piece.. the part was pathed at 0.005 path to model tolerance but the arc fitting happened at 0.01 tolerance arc to path, so some averaging of the resulting arc occurred.
note in top pic the line is perfectly smooth over X, no stl faccetting to be observed. perfect RC.
bottom one plenty evidence of facceting but no striping.
Im interested in testing this again. I also posted a clip o it

What are you using for a spindle? Watching your videos, it seems very quiet.
Vince

NSK 2530E and yes its whisper quiet :)

What's the HP on a spindle like that? I can tell you mine is la-oud! I gotta wear hearing protection. Is it only designed to work in soft materials like wax/resin?
Barry

here is the specs on it. It can cut metal and runs up to 30 000 rpm, I however only ever cut plastics wax and on the od ocasion AL.

Hi Chris,
Super! I've read/viewed just about all your offerings and haven't found an answer to a question I've been pondering throughout.
This may be a silly question..but:
When you create your pieces in wax for later fitting of stones and such, what percentage do you make the wax model bigger(if at all) to allow for casting shrinkage so finished cast isn't too small.
Again, I've recently 'discovered' your output and, having hand crafted jewelry in the past, am simply in awe of your work!
Many Thanks!
John Bloy in Wisconsin
-
;)
the reason i never discuss that is because its a complex question depending greatly on the post casting production that will be required on the piece.
If i am simply producing a piece that will be cast and finished directly i usually allow around 1.5% to 2% to allow for the small shrinkage that happens at cast time, but if its going to be vulcanised and recast the cats really out the bag, and up the tree, with the wifes best bacon bits and the pastors wig...
cutting masters and allowances in the original model can vary greatly with as many iterations as their are jewellers. rubber moulds have linear shrinkage for example so scaling has to be directional as well as general etc etc etc.. but metal mould processes are completely different again.. so .. no easy answer im afraid ....
too complex to cover in a single mere post, and a great many boos on lost wax casting cover all these issues :)

Thanks Chris,
I take it then, outside of the general numbers you gave, that experience would account for your mold-making techniques.
You've obviously mastered all the complex issues you mentioned regarding shrinkage from wax to metal.
Thanks again,
John Bloy

Folks.. from time to time I get to cut rings for Colin(colwax), and man, let me tell you , he designs some lovely one, but !! BEEEEEEG!!!
Most we are not able to post but this one I gotten his permission to post with, so I have decided to do a video tutorial for Rhinocam on this one too.
Without further ado :)
A sneak at the paths involved, 4 tool changes and heap of paths, this will be in video, the rest is methodology :), the only thing more interesting about this job is that it features a hollow head, ie: its not cut through to the finger and has a thin sleeve inside, so accessing those hollow area from the top at various angles was a fun exercise

Very nice job Chris,...you too Gert.
Room in there for a bit of a "stash" eh ? ::)

lol ya now you mention it.. i see a new line of jewellery.. Stash Rings :)

lol ya now you mention it.. i see a new line of jewellery.. Stash Rings :)
In this case, i just might begin to wear jewelry! ;D

Hehe....stash rings. I'm afraid the 80's coke craze already beat ya to that one, so much for the "new" line. Besides...I'm sure the clientele would not be nearly as pleasing to deal with.
Looking forward to the video, Chris. Nice job as usual.

Fantastic, just amazing work, but I guess you're probably getting tired of hearing that, huh? ;)
Thanks for sharing, Chris-

What kind of stone is that?
-
Hey Chris,
You do fantastic work but I do have a rather dumb question........ ???
Do you wear any jewlery ? Have you ever made something just for yourself or the better half?
RICH
-
I have a drawer full of rings i never wear.. i make them on impulse, wear them for a brief period then shelf them... the madam has a similar drawer.. I make jewellers jewellery for her. technical marvels but usually but ugly ...
;)
@SAM
thats a star sapphire :)
-
whats worse than making one hinged ring....
making two hinged rings.. its that time of the year again ;)

Tweakie.

I am cutting this for someone else, its hardly an earth shattering design and i could have just done it as autoflip and rotary.. but.. I figured, what would be the most difficult way for me to do this..
Figure out the curves.. and cut the entire job as a 2d profiling and pocketing operation..
2 things i learned..
1: 2d work is trickier than it looks
2: In 2d this job will take 47mins.. in autoflip+rotary i was looking at 7 hours...
have a few other job on mill so just sims for now ;)

he exercise here was completely hypothetical, to see if i could produce a piece of jewellery on a mill with no actual geometry, only 2d curves..
it was a resounding success, and not only that it was FAST.. i sim'd it at 400m/min but cut at 800-1000 average velocity, 22min total cutting time :)

is that broke?, you make nice stuff ;D
-
lol no its to be cast in two colors, white gold top, yellow gold bottom :)
-
i have been fielding lot of emails about "methods" or "strategies" when it comes to milling. I always answer similar to this.. If you had to make it by hand how would you go about it. most people would have about 10 different ways to do it. milling is the same. look at what you are making. how hard it will be to clean up. what material you are casting in etc. and develop a strategy based on your needs. no magic bullet strategy's im afraid ;)
I almost had this one grown but decided wall incline vs damn grower lines was worth the post casting cleanup :)
I was going to assemble in wax but decided i prefer to polish inside then seat solder in platinum after casting.

I have long been enamoured by the fixture from Lex at DeskProto and after some discussion he happily provided me with a unit for testing. I have copied this post from our old forum where more in depth information is available.
I locked the fixture into my Sherline rotary and the time arrived to dial this sucker in!
The fixture relies on a perfect A and Z and X setup, Y and Z should both already be setup before you even set this fixture up since you will be locking into your rotary unit and would have this dialled in.
Lets get to it!
1: Finding perfect A... easy! roll the whole unit in A against a table square on your mill table, set your jog to 10% and slowly roll until no light is visible between the square blade and the fixtures top surface.
(http://lh4.ggpht.com/_E5AvLF8D7WU/TDepGxb1sKI/AAAAAAAACpg/fk1QOCVDD7A/s800/123waxring.JPG)
2: Click in the A DRO in Mach and type in 90 (or 270 depending on which side you setup the fixture table) then run the command G0A0. Simple - A is now perfectly flat to the spindle and A is now set :)
(http://lh3.ggpht.com/_E5AvLF8D7WU/TDepHLvb9hI/AAAAAAAACpk/gmvLgzjKwz8/s800/123waxring%20%282%29.JPG)
3: Time to setup X.. this too is pretty easily done, but make sure you are 100% carefull in this step, the 123waxringWizard software relies on X heavily, even a minor misalignment here will be amplified in your final model.. measure twice, cut once. To setup X drive the back of a 3.17 (1/8th) cutter up to the very edge of the fixture like below, CAREFULLY, set your jog speed right down when you get closer. when you are touching the fixture zero out X and drive directly upwards in Z away from the fixture, now time to correct our tooltip width, run the command G0X-1.585 then rezero X. Thats it for X.
(http://lh6.ggpht.com/_E5AvLF8D7WU/TDepH_XHR8I/AAAAAAAACps/uSPK3U7yuBI/s800/123waxring%20%284%29.JPG)
4: these images are merely the way that I verified my Y before cutting, I am including them because all thing swith movable parts are subject to tolerances so screwing the fixture into its Sherline adapter may introduce errors, and even tho they are minor in most case its good to know how to look for them. Basically i drove my cutter to the very edge of each pin in Y and check the Mach DRO for position in Y on either pin, these should be virtually the same number only different in positive/negative assignment. Y verified!
(http://lh6.ggpht.com/_E5AvLF8D7WU/TDepICdOvAI/AAAAAAAACpw/gwwKtKHp4Ao/s800/123waxring%20%285%29.JPG)

5: Time to cut.. The software would have told you what thickness disk to use, lock it in the fixture with the chosen cutter in place and probed.
The first path will complete with half the disk cut away to reveal one side of the ring.

Turn the disk over and lock it back in. Cut the second path, you should be left with a well aligned flip cut wax, ready for the final rotary pass.

Lock it onto the rotary pins and lets finish this up!

Looks easy Chris. :D
Can you make your own wax for this fixture or do you have to buy the ready made blanks ?.
Tweakie.
-
You can make or buy them. The company that provides the fixture and blanks also supplies cad and nc files for making your own blanks as required. The holes are critical to accuracy. I think that at around $3.50 per disk which will results in a $500 to $10 000 piece of jewellery simply buying them is cost effective? but I do understand that some folks, like myself are closely related to Mr Scrooge ;)
-
Thanks Chris.
One more, perhaps silly question. What is the best way to remove the wax chippings off the finished work ?. (the tiny bits of wax seem to stick to my stuff).
Tweakie.
-
blaster!!!!!!!!! woooooooohoooooooo thats the best thing about this job i get to use a high pressure water blaster to clean the compaction off tiny fine wax cuts!!
see here
http://www.redarrow.com.tw/products-yh170.htm
available in the US rebranded as Mystic at about 4 times the price.
BEWARE, turn it down to its lowest setting, it will split your skin open instantly on its standard setting. (i know this from experience)
-
Thanks again Chris, now I know why some of your wax photos have water droplets on the surface. ;)
I will look out for one of those blaster's 'second user' (I'm 3rd generation related to Mr Scrooge also).
Tweakie.

PS.. these are used for removing "protein stains" by washing houses..
protein stains?? mwaaaaaaaaaaaaaahahahahahahahahahaahh

Thanks Chris.
Protein stains........ Where I grew up we called them skid marks. ;D ;D

Its no secret that my wife does all my milling... And a good job to... and now day she does virtually all my pathing as well.. but.. the layer colors!! for petes sakes! :roll:
Gotta love a gal that can write a complex multipass multiangle path!
These are masters for a articulated necklet. wil try grab images when its done.

Atta boy, Chris!!!
At the first of June it was...."my wifes first multisided index job!"
Now it's...."my wife does all my milling... she does virtually all my pathing as well....can write a complex multipass multiangle path"
Now THAT'S what I call training. Nice job letting her know that she 'still ain't there yet' by complaining about layer colors. You can't let them get too sure of themselves, or they might start thinking they are closer to an equal, rather than an underling. The next time she's working on something, step in and change some tiny thing that don't even make sense. Of course she will say "why did you do that for?" Upon which you will reply some totally off the wall crap, that you make up in your head such as..."Because that's the way it has to be done. Otherwise, the tool used at that spindle speed, cutting WX-233 impregnated wax in a microdyne constorted fashion, would surly make a mess of things in a hurry. I won't even go into the other mistakes I see because we can live with them for now. The important thing is...your getting there, but there's still a looooong way to go"
Then you can walk off, and go finish watching how Shaggy and Scooby solve there latest mystery, or Meerkat Manor or something.
Awesome job, Chris.

Keep this up Chris and you will be the first person to exceed the licenced Mach maximum line limit. ;D
As always excellent work.
Tweakie.

is there one????
wow??? never considered that? the longest path in this series is about 1.2million lines and the rest are saved out in a per index fashion?
not got to cut this yet, probably tommorow actually, hope i dont hit a snag?
-
Mach3 has a limit of 10,000,000 lines of Gcode even after licensing.
Still a way to go Chris. ;D

Why the switch to DeskProto?
-
RhinoCam rides on top of Rhino, rhino has a max mem usage of 3gb so very large mesh files with tight stepovers are nigh impossible to path in RhinoCam at current. I hope the release of Rhino5 64Bit will mean rhinocam goes 64bit too :)

That is truly amazing, from concept to part how many hours are in something like that?
Graham

Hi Graham,
I was only a small step in this project, the client is nto mine nor is the design, I was simply the prototyper in this case so I am unable to tell you how long the design took but I can tell you thsi ring has been worked on by three people so far to bring it to completetion, i will post Colins remarks below on that.
As for my bit, hmm 30 minutes for pathing, an hour of wax setup and about 5 hours on the mill all up then about an hour of post milling cleanup.
Colins remarks
Hi Everyone,
I'm extremely grateful to Bert & Chris for their assistance with this project, so a really Big Thanks goes out to both of you!!
OK, here's the basics of this:
A Retailer that I'd previously done some CAD/CAM work for had a Customer wanting a Crest ring to be made.
The Customer supplied their ideas & info on how they wanted it to look & the overall size they wanted it to be when finished.
Apparently the Customer knows someone that'll cut an Onyx the shape of the Shield & also carve the Crest details onto it too.
So having sorting out most of the "iffy" details, I consulted Chris on the making of this model, especially as he'd be milling it.
Chris & I both agreed this model was best suited being made with ArtCAM.
Chris had a very similar project made by Bert, so I asked Bert if he would be interested in doing this model for me.
Luckily for me Bert said "yes", so a price was agreed upon & Bert proceeded to work his magic on this design.
A couple of screen captures from AC later & then Bert supplied me with a 3D PDF file to check out the completed model.
This model then went straight onto the Customer who finally decided it was good to go.
So this job was conceived in the outer suburbs of Melbourne, Australia...
...to be created by Bert in the USA...
...to then be milled by Chris in the outer suburbs of Melbourne, Australia.
It truly is a "Global Marketplace" & this is a "Global" piece of jewellery.
So once this wax is supplied to the Retailer, that'll be the last I'll see of it unfortunately.
If I'm really lucky, I might just be able to score a photo once it's all completed...if I do, then I'll be sure to post it here.
Here's a collection of the various screen captures & renders that flew back & forth across the Internet for this job.
regards Colin

I'm so used to seeing perfection, so I've just got to ask the story behind the marked area....
-
:)
dropped the piece onto my workbench while coring it, basically the ring get cut with no fgnerhole then i file it up by hand. irksome job.. if you check the dragon ring from a few posts ago very carefully you wil also find one ding ;)
these things still hae to be cast and tumbled tho and the 0.005 cast finish and 0.005 tumble flattening tend to be a great equalizer :)
-
Simply......friggin amazing, my friend 8) ..... that appears to be a huge ring :o
Dave

Chris, I wish I could do the same thing as you do.
Wonderful work my friend.
Jeff

thanks guys, things been slow actually, may need to jump into another industry at some point in the future.. any tips? hints, what can i do other than jewelry that I can apply my skilset too guys?
anyway, that said here is the kind of job milling was made for... Lucky Caro was cutting ;)

Chris,
check out the field of micro machining, this is a boom industry mainly for space and medical sectors but plenty of money for the ones that can do it.
Don't tell everybody though ;)

Hi Chris,
Fantastic work (the norm for you!)
I see the pic of your webcam for $50 along with the several magnifications.
What brand is that?...And has it been highly modified to suit your purposes?

been a bit since i posted guy, sorry. been busy'ish.
I had a nice project to work on here.. saving grannies ring.. this mount is super old. the stone is unrecognizeable cut too. im guessing some windowed rough.
Doing a job which has this much sentiment and very littel actual design characteristics left is always shaky business.. Granny will remember it like the day she first got it, and you need to try live up to that...

Wow. Great work Chris. Being an older ring, was the amount of original detail considered to be high for the period?
-
That is just excellent Chris.
I really look forward to seeing your postings, don't leave it so long next time ;)
Tweakie.
-
hey guys, thanks :)
those pieces typically were stamped and assembled. its possible it was hand pierced but unlikely. the level of detail in jewellery has actually gone backwards over the last 20 years. simpler stuff, with cleaner lines seems to be more the order nowdays. But, i service top end lines so in my workspace typically 99.99% of the ring is all about the stone and only marginally about the ring itself. back in the days when diamonds were scarce this was the reverse.
-
all about the stone and only marginally about the ring itself
what a bummer. :(
-
Chris,
As always appreciate this thread and the work your do.
I just went over this whole thread searching for some info since I just started fooling with 3d machining.
Now i have an even greater appreciation for the micro work your doing and the equipment required to do it.
Thanks,
RICH
BTW, My little mill can only run 4 IPM, guess i will be doing a lot of reading. ;)

Scott, those videos demonstrate your keen sense of humor with your wandering camera work. ;D
You are truly too showing just how up for the tasks Rhino/Mach and your selected hardware are.
I recognze you as a Master with a Doctorate......and then some!

Ya!
(except for the nasty copyright business of course ;) ) this ring has been the subject of much discusion on our forum.. mostly regarding the dangers of late night "emailing" alone in front of teh computer whilst wearing it.. can you say "circumcision"
actually i will be milling that bangle.. going to be a disaster to path.. it has to be hollow too.. so splitting that sucker up like a spatchcock chicken...
-
just spatchcocked another job a bit back too, to give you an idea of what i mean..
that superglue sure is good stuff.. just dont get it confused with lube...

Hey Chris,
That snake bangle ring is eye catching, but, as you said the modeling would seem to be a challenge. Some how believe your up to it from the work
you have done and posted. Give it a try and remark about the tech difficulties in doing it. As always enjoy your posts.

had that sucker grown guys.. was too much headache to mill. i admit defeat!

So you made a bracelet instead?
No defeat.....you just need to think about it a little more.
Heck, all the guys in here wanted to buy one for their better halfs , that comes to an order for about 10,000 of them. >:D
$100 profit each to you x 10,000 units = $1,000,000 :D

hehehe .. actually im quite liking it myself, thinking i will scale1d for wrist width and have it made by Shapeways in stainless.. only cost about $100..

The Cross :)
The brief was to make an ornate cross, 90mm high by 65mm wide with scrolly work in it..
I drew the base with Rhino to get us as far as a weight estimate then filled it in with tsplines for the curly wurly stuff :)

Hi Chris,
Nice to see you'r back here again.
We have missed seeing the pictures of all your wonderful creations, now it looks like some great stuff will be produced with that new axis. ;)
Tweakie.

Still have the same haircut???
Jeff
-
Ha! nope .. having hair at all is an issue now days..
here is a copy of the build to so far from 3dcad.. its ALMOST there, my last headache is wiring the limits built into the A and B axis'
I made the decision to add a 5th Axis to my Minitech Minimill 2 as a hobby project.
I bought a second hand Minitech 5th axis trunnion table unit from fellow forum member Stewy, and assigned a little time each weekend to work on it.
The initial arrival was a worry as it looked far to big for my table.. but it worked out ok.
The BEFORE shot:
(https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xap1/v/t1.0-9/10428423_311344922388115_2316334287376554143_n.jpg?oh=8ab5e415d1f6306ee1f3cf5a7cc5d4b6&oe=54E0EB85&__gda__=1420418393_4f7cbbad523b0757c722e34650e686b6)
Getting the 5th Table positioned required some poking around before the stripdown occurs.
(https://scontent-b-sea.xx.fbcdn.net/hphotos-xap1/v/t1.0-9/10712752_311345002388107_2349309576131232452_n.jpg?oh=7a5ebc22c81d51222aa1dd8868bf812d&oe=54B37277)
4th Axis off...
(https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xpf1/v/t1.0-9/1926938_311345049054769_8459148749236946558_n.jpg?oh=9333ad612b10999579fc6a06def69fdf&oe=54AB439C&__gda__=1420418653_9874474cff1e2f39b08be6d034f1a553)
Tool Probe off, XY table ready to fit the trunnion.
(https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-xpa1/v/t1.0-9/10689877_311345245721416_7278328936841146210_n.jpg?oh=00bda7522b64c8ed797a97f4b42a4482&oe=54F19429&__gda__=1420861329_0d4ee9a15098bc0e8b22dbdab20c0b47)
This position is the only way it will fit and still allow access to the tool probe.
(https://scontent-b-sea.xx.fbcdn.net/hphotos-xfp1/v/t1.0-9/10391399_311345275721413_7775205920910478063_n.jpg?oh=d4e50ec8f57c63d7fbb5e2c2f7905859&oe=54DD8259)
Probe is available.. Just barely..
(https://scontent-a-sea.xx.fbcdn.net/hphotos-xpa1/v/t1.0-9/9759_311345545721386_3316576429534959205_n.jpg?oh=3d88c78bbcf55ae526e5b49e744f2ef1&oe=54A9DB19)
Cutting forward of the table is impossible.. but the back 120degree of A and teh full 360 of B will suffice
(https://fbcdn-sphotos-e-a.akamaihd.net/hphotos-ak-xfa1/v/t1.0-9/10690020_311345549054719_3719238868212415379_n.jpg?oh=aed6c9c41d1926c4108642d7f0d3a3fd&oe=54B170B8&__gda__=1420655502_5bd043581eb6e12640449b05b6b107b2)
The wiring!!:
I solved my 5V issue by using an external PS 5V 1000ma. It is wired it to a plug socket so that swop out will be easy if this dies (see white plug point wired in the back)
From the initial layout to get motion, the task of fitting it all in the original controller box seem daunting.. but a beer later it was solved.. sometimes resolving an issue requires walking away from it and coming back..

And its all in... Again a very tight fit..

I also mounted the B driver board to left of the main 48V power supply

As for the B driver I had to reduce it from 2.7A to 2.1A, in my burn in test B stepper was running way to hot.. I wired it to the only space left, above the power inlet.

and all assembled and running! (still need to solve the A and B limit wiring)

I have no hard data for the stepping/microstepping of the B axis so some poking in the Motor Tuning got me to a guesstimate of about 1250 steps/per, which after tests below of 20 and 40 revolutions of the B axis turned out to be pretty accurate.. (I will go play the lotto next!)

Then Lifted Z, and ran B7200 in test1,B14400 in test2.

Then drove Z back down to photograph and examine. EXACT as far as I can tell.

And the Burn in running!!!

The "run in" code i wrote it longhand so use with caution whomever else may follow this thread in future, it relies on you already having zeroed out stuff in safe distances.. it then loops a reasonably safe bit of code 50 times. "reasonably safe being relevant to your experience level...

Very nice job
Any problem programing with 5 axis?
Jeff
-
pretty good question as ive not actually written on and run it yet.. I got the 5th axis version of RhinoCam and took a poke at it once so far..
the pathing is easy.. its doping it so it doesn't hit stuff that wil be more challenging..

ok so i progressed..
the machine is pretty much modelled so i can detect crashes and I have written a few paths to play around..

Hi Chris
I like the idea of having A & B axes.
But I worry about the layout of the electronics. I had a very compact box like that once. It was fine until it stopped. Then I found out just how hard it was to work on it! Verged on the impossible. OK, it WAS impossible.
My current electronics system is very much '2D' in layout. You can get at everything from above. Debugging is easy. Since my system has just had a total rebuild, that was a bit essential. Yes, total: replaced the USB SS with an ESS, added two MB-20 BoBs, replaced the old (dying) servo drivers with Gecko 320Xs, replaced the (spectacularly) dying SCR-based KBMG spindle drive with a MOSFET unit (much quieter motor but the RFI was incredible), and added some custom interface cards and opto isolators for the encoders and the eStop system. Getting a CRO in there was so easy from above.
Cheers
Roger

Setup all the homing and G54 offsets at last

and finally some wax on her..

Excellent work Chris - that looks like it is working just fine for you now.

Hey Tweakie, long time no see.. thanks dude. Yeah the X is still way off, if you watch the last cut from A0 you can see the "offcut" wax has thicker areas in X.. TBH havent dailed in X and Y yet, but 5th is quite forgiving ;)

Hi Roger, yes, been thinking about a rebuild of the controller,
I actually have a old server that is in a MASSIVE case.. and its current board is more than ample to run Mach3,
and if i dump its raid array and dvd rom bays, the driver boards etc would easily fit..
but..
that is a project for another day.....

Hi Chris
Go for it.
I am embarking on my fourth rebuild tomorrow. Replacing my hand-wired custom opto interface boards with engraved PCBs, and replacing the rats nest of wires with properly organised (and screened) cable bundles. The big blocks - ESS, BoBs, Geckos etc, all stay - although one or two may be moved slightly on the 3 mm Al plate chassis.
Cheers
Roger
PS: that wax sure cuts easily!

SO all looks like its running ok!

Absolutely brilliant work Chris - well done you and your mill. ;)

Yeah, 'orrigh. Not a lot of TIR there either.
(Drools quietly in the background.)
Um - just one Q. How do you make sure there are no wax fragments left on the master before you make the mold? Brush? Vaccuum?
Cheers
Roger
-
it depends what you cutting with, usually i use a tapered ballend and there is not need to clean up with more than a soft paint brush, but with pyramid (3 flute) or profile tools you can get compaction in narrow spaces and this si very much dependant on feed/spindle speed, too slow it compacts, too fast it melts back to the surface, in either case you need a reverse vacuum watergun to clean it up.. dangerous when you have parts with fine detail..

Hum - sounds a bit like dentistry (I think). Light cuts with fast traverse?
Does an air blast help?
in either case you need a reverse vacuum watergun to clean it up.
Is that also like what a dentist uses?
I am being educated. Thank you.
Cheers
Roger

uhhhh.. its called a spot gun. it has a motor that generates a vacuum that creates a very high velocity microstream.. so high that if your fingers cross the stream it injects the water under your skin creating instant "blisters".. you were warned...

Could be a higher pressure than the dentists use ...
