Got an Email that said I would be deleted if I don't post so here you go a post ... I would hate to be deleted :)

Very nice Litho Kent!!!!!!!! What program did you use to generate the code?
Brett
-
Thanks Brett.
I used Vectric PVC and VCP I then use Mach3 to control my Joes2006 http://www.cnczone.com/forums/showthread.php?t=32790 Now that you got me to look I guess I have been playing for 18 months or so. Little slow on the build . But as I knew absolutely nothing about CNC 2 years ago, I have been trying to learn how to use it. I do need to spend more time learning the Mach3 software. One reason I don't want to be deleted :) I am hooked on CNC and Lithos. I have lots to learn and hope to build a few more CNC 's So it would definitely be a bonus to learn mach3 better :)
-
Glad you have been looking Kent and again, very nice Litho.
Brett

Hi Kent,
Brilliant tiger - Could you possibly share the GCode for this so that I could cut one ?.
-
They should delete you anyways.... for not posting those pics sooner!!! Good job.
-
Sam, Sam, Sam. ;D
You do have a good point though. LOL
Kent, I have a good frien that use to be an Artcam reseller and still does lots of work with them. He is crazy good with Artcam and if I'm not mistaken, he worked pretty close with some of the litho pioneers.
I have attached a Picture of one he made for me.
Brett
-
Some really beautiful work here, thanks so much for sharing - :)
Dave
-
LMAO thanks Sam needed a good laugh here is a link ( easier then finding the pixs) and one more picture hopefully makes up for lack of posting before this :)
Thanks everyone else and Brett That is a very nice litho thanks for sharing

No doubt Kent, I crown Sam with the CROWN OF GIGGLE BOX. ;D He is funny. Some days he just come in a kicks my giggle box right over. LOL
Brett

Everybody needs a chuckle now and again. Glad to be of service. Ain't nothin' in life free though. That will be $1.57 please.
-
I'll gladley pay you Tuesday for a good laugh today. ;D

A big thanks to Kent for a copy of his code. Such a wonderful white tiger.
I reduced the image to 1/2 size but even then it took over 8 hours to complete the 342,000 lines of code.
I have included images of the finished lithophane, the half way stage (after 4 hours) and how I amused myself in between doing other things on what will probably be one of our last summer days this year here in the UK.
-
As usual, very good Tweakie.
Brett
-
Indeed, and a good choice for a nice "crisp" refreshment as well - ;)
Dave
-
Looks Good Tweak, and your welcome.
by the way the 10 inch version only took 3 hours give or take 15 minutes ...
-
Hi Kent,
I think you said that you used 'Corian' which is perhaps not so prone to melting as the 'Plexiglas' that I used so I had to reduce the feed rates quite a lot. Not sure if I can buy Corian here in the UK but it seems a good material to use for all sorts of jobs.
Once again, many thanks for the code.
btw. If you post any more Lithophanes I will be on the scrounge for the code you know.
-
A source of corian might be a place that makes Kitchen (http://en.wikipedia.org/wiki/Vance_Miller) or bathroom counter tops. You could prolly get it without much effort there. Corian is also great for making 3D stuff too. Check out Scotts post here. http://vectric.com/forum/viewtopic.php?t=821. I would love to get some nice thick slabs of it myself. I bet you could make some nice turnings with it. The litho's look awesome, by the way.
-
Sam gave good advise on where to find it . They also use it for shower / bath walls this will only be .25 thick :)
I have been buying .25 off of eBay . I have a good stock of .5 inch I befriended a guy who works in counter top business,
so I get some cut outs and other stuff they don't want :) I make him some templates,signs or what ever else he likes ...
I got a piece of white extruded acrylic, I am going to give it ago as the corian is expensive and hard to get . The corian is real nice doesn't scratch easily,
I am afraid the acrylic will .... you can have reweld problems with corian if spindle to high and feed to slow ...
Have a good day Kent
-
Thanks Sam
Thanks Kent
I am going to start looking for it.
-
Heres the newest litho ..... 2nd pic for ref tiger 10x10
-
Another good job. Way to go Kent.
Brett
-
Nicely done.
-
Thanks Brett and Sam .
-
Again, brilliant work Kent.
Not too sure about the repair to the BBQ lid though.
Tweakie.
-
LOL you must be taking over Sams place... Not a repair, The temp probe was in the way. I
couldn't rotisorie/smoke my turkey so I adapted the probe.. you mean you don't like the generous use of aluminum foil ::)
-
Kent,
Beautiful work! But you can't slip anything past Tweakies eye! ;D
Keep up the great work!
Glenn
-
Naaa, I'm not threatened. I seen the temp mod, but I knew exactly what it was for. What really stood out to me was the reflection in the tigers eyes. You can clearly see the glass observation windows. Looks like the San Diego zoo. Picture was taken around 2:30pm. Mid April. Light breeze from the north-west.
-
;D roiling on the floor laughing.
Brett
-
Kent,
Thats some nice work. By all means post as you fiinish them.
RICH
-
Sam you are too much... Thanks again for the good laugh.
thanks Rich Brett and Glen for your kind words and support .
-
When it comes to 'Eagle Eyes', Sam is the boss.
Yes please Kent, post the pics as you finish them.
Tweakie.
-
I am just glad eagle eyes didn't point out the Y -axis missed steps in my daughters litho ...
I am sure he would of had to explain how that happened :-X ::)
-
So as not to offend Tweakie with my totally time honored, family tradition of BBQ repair with high grade aluminum foil ...
I replace background with bubbles .... really wish someone would wash the widows around here ::)
-
Another nice one Kent. I think you must be the lithophane master. Keep it up.
Tweakie.
nb. Bubbles are not bad either.
-
That looks good too Kent.
Brett
-
I was 1/4 of the way thru my second pass on a litho I was doing of my grandparents when I had a bearing seize in my spindle. man was I hear broken. It was looking really good too! :(
-
:-[ that was looking great.
I just love the detail on these -
Dave
-
Hey Fixittt,
I don't know what the finished product should look like, but from my perspective, I'd say you can still use what is already cut!
Looks good!
Glenn :)
How much $ for the new spindle?
-
notice that in the females face there is a line, left side is lighter because it is deeper.
it cost me $35 to order 10 her bearings. not to bad, just bad timing. I used artcam to make the relief. My desktop cnc machine has a wolfgang engineering spindle and I used a 1/16th ballnose endmill. Smallest I had that would cut this material as most of what I do is wax.
Here is one I did a while back in purple wax. The 15 degree .005 in tip cutters I use for wax I dont think will cut the white plastic.
-
Both look nice fixittt. I hate your bearing went out. How long did it take to machine them?
Brett
-
They are all great and it's nice having experienced resources should i ever want to try it out.
RICH
-
I hate when the machine hic-ups when doing a litho... I have lost a few to z axis problems
Then I do something like drop one :'( I dropped my crucifix ... So I cut another out of Arctic white , first was bone .
I did super clue the first here's a pic of them side x side.. ... used the eagle to hide BBQ fix :P
-
Another nice one Kent.
Best regards,
Tweakie.
-
I have about 2 hours worth of machine time in each.
I was wondering, what cutters do you guys use to do these? I am still new to this and am looking for smaller size but good detail. Any tips? Tricks ect?
-
The cutter I used to make the copy of Kent's wonderful white tiger is this one. It is solid carbide, single flute, reground ballnose shape, 3mm diameter. Not the smallest I have but it's a tough one.
Tweakie.
-
I'm not sure of the cutters my friend uses. I'll ask him. I know drastic reductions in machineing time can be had if you can stand to lower the res.
Brett
-
I use 30 degree V bit both .25 and .5 inch I tell the software that they are 0.03 ballnose .Here is link to picture the other 2 bits are v90's
http://www.cnczone.com/forums/showpost.php?p=353705&postcount=140
I am able to make one pass .2-.23 deep with these bits ( BSimage from vectric site came up with one pass cutting with V bit)
I use these bits when ever I need high resolution. the portrait of my daughter was done with .125 Ball nose .
Tweakie ( not my fence , I rent . and not going back to bubbles ;D lol thanks for the laugh )
-
Hi Kent,
I deleted the bit about the fence because I thought that otherwise I would not be able to post anything again, unless I used bubbles.
Best regards,
Tweakie.
-
just got done with this one, wish I had a smaller cutter I used the 1/16th ballnose endmill again. Will work for a gift for my grandparents anniversary
-
Good Job. That will make a nice gift.
Brett
-
Brilliant work. I think they will be really pleased with that.
Tweakie.
-
Very Nice fixit, I found this picture begging to be a litho ..
after I took the picture of the litho I named the Guy Tweakie....
See how he's trying to fix my BBQ ;D
-
When you said it was a time honored family tradition, you weren't kidding, were you! It goes waaaaaay back!
-
;D A tradition well worth passing on IMO.
Brett
-
Another great one Kent. ;D
Tweakie.
(I wish I was that skinny).
-
(I wish I was that skinny).
I am ... Just don't have four feet :)
thanks guys
-
wow that is mind blowing!!!!!! VERY NICE!
-
Thanks Fixittt , what is really cool is 1.5 hours into the job the tip of my .25 V 30 bit broke ( they are needle sharp,maybe sharper even)
It broke maybe .02 off the tip, definitely noticeable in the carving. I stopped the work re zeroed my Z axis, backed up 20k lines of code in Mach3.
started the code again. I can not even tell it happened... Thanks to MACH3 ....
-
i would be veru interested in any steps you take to clean up an image and get it ready for litho work.....
-
You caught me... This photo was real small and I should of photochopped it to get little clearer. I only masked
what I didn't want to carve. Then used Photocave to fine tune the contrast and make the code. imported in to Vcarve
created the cutout vectors.
I normally will try sharpen the image if needed, I have also used the blur option. I will also subdue any hots spots ( light glare)
I wish I could give you better answer, I just go by how it looks to me and how it looks when ran through the PVC software ..
I wish I was better versed in the use of photoshop. Hopefully this dog is not to old to learn ::)
I have Aspire software, So maybe in the future I will learn how to get it to do my lithos,but so far I am more then happy with the PVC program.
-
caught you hell! Its pretty friggen kick a$$ if you ask me. The reason I asked is that I use artcam, and the picture have to be really good from the start to get any descent result. You have the experience, I have the will to learn. Unfortunately I do not have the PVC software.
-
caught you hell! Its pretty friggen kick a$$ if you ask me.
LOL thanks, But I really do have to give credit to the Vectric Photocarve software,
and the information on how to cut from the fine folks at the vectric forum.
you really should look into the PVC software quite reasonably priced,
If you plan on doing lots of lithos it is worth every penny ...
-
Here is Logan, 7 in tal x 5. something ... ::)
-
Brilliant.
Tweakie.
-
Kent,
Sent you a personal message.
RICH
-
Thanks Tweakie...
Rich sent PM
Here is Logan twice, the first and a second cut in Bone . I removed the extra material between his ears this time..
apparently I had nothing between my ears when I photochopped the first time ::)
-
Here is an Eagle head I cut . 10.5x10.5 inches I think it will look better as sun catcher
-
Hi Kent,
I think the bone for Logan is just perfect. If he doesn't like it he can chew it !.
Regards, Tweakie.
-
Here is crucific with frame
-
Nice idea on the frame. Looks superb!
-
Great!! :)
The frame fits spot on!
Keep up the great ideas. Glenn
-
That is truly brilliant my friend.
Regards, Tweakie.
