Ok, so as most of you know, I've been putting together my first little CNC from scratch. Well, maybe not scratch as I started off with a Taig "manual" Micro lathe and put together a little piece of art - :D
I'm still very much learning about all this and need to learn a LOT more before I'm making any useful parts with it. It needs to be fitted with home/limit switches and other assorted schtuff but I'm getting there slowly but surely.
As for the video, I have no idea what I'm doing so bear with the editing and all that crap.... lol!
All in all, I'm seriously happy so far with what I've got and I promise to get some nice still pics of the unit and explain more about it later.

Thanks,

Good Job Dave. You did a good job on the video as well. Isn't this stuff addictive? You get to learn much more than just Mach (as if that isn't enough) in the process. ;)
Brett
-
Indeed it is addictive, Brett.
What sucks is I have a family and 2 jobs so it's so hard to get a lot done with it but I'm hoping having these little cnc's will create more time for me
.........ahhhh...who am I kidding, it's only going to allow me to make MORE parts (read "work") :D
Thanks,
Dave

EDIT-FAIL---

Dave, on your last test, i just went in and deleted the quotation marks ".
Brett
-
Ah, ok, thank you, now I know...... ;)
-
No problem.
Brett
-
Some more pics for you as promised....
I setup some home switches today and made the z axis adjustable to be able to have my z home wherever I'd like using a stainless steel adjustable rod on the headstock. I think this would be a pretty nice feature since that position may change with certain jobs that would be done.
-
More pics since we're only allowed to load 4 at a time:
-
and a few more of the home switches, not yet wired, of course- :P
-
Beautifull job budman68 , here is my taig I will over the winter do a second unit with proper steppers

Thanks, Peter and thank you also for sharing the video.
Absolutely great stuff - :)

Dave,
Keep it up and you'll need a shop expansion.
Nice lathe and hope it works well. You got to admit there is definitely some satisfaction
in building your owne stuff.

I don't know Rich did I miss something here
-
Pete,
When i watched the video from your link above there was morse code in the background and figured that
you deliberately put it in. Maybe it''s just me as the same thing happens when i go to the grocery store check out.
To manny radio operator code competitions. I quess.
;D RICH
-
Nice work, I like the 10K rpm ;D
-
Thanks fellas, it's a lot of fun, that's for sure....-just wish I had more time....... :D
Dave
-
LOL......no Rich thats part of the song but yes it kind of does now that you mention it ........maybe it is................ ???
Sorry for hijacking your thread Dave , what upgrade do you have in mind next . Nick carters website is a goldmine of idea,s
-
lol, no worries, Peter, that stuff doesn't bother me at all in a "show whatcha got" kind of thread.
As for upgrades, although I'm a sucker for gadgets and add-ons, I think I want to take the time and actually learn how to use the damn thing. :D I'm new to the cnc thing to begin with and I've come a long way since only a year ago when I bought my taig but the cnc lathe is just a whole different animal to learn to program. I don't even have a decent CAM program for the lathe yet as it's either pull your hair out with something cheap or spend $800-$1200 for something that I know nothing about. Sure, there are demos out there but I've found that sometimes you still don't like a product even though you've had some time to test it, ya know?
I would like to make a nice heat sink for the DC motor, alomost like a covering of aluminum fins. We'll see, I'm sure I'll think up more schtuff along the way- ;)
Thanks,
Dave
-
Kind of like this
http://www.youtube.com/watch?v=unRYa0NRBaI

Yep, that's definitely on board for the mill. I just need to finally break down and buy a friggin sherline and a stepper drive and I should be good to go. :D
What's the part you're making?
Thanks,
Dave
-
I was just getting my feet wet with the 4th axis and writing the code , on my boats the electric motors are watercooled and I figured a cooling jacket with fins would be cool . This was just an experiment to see how 50 and 60 fins would look and is now sitting on my bench as a paper weight , when the new motors come in I will make the jackets with fins going from one end to the other
-
Ah, very nice, that should look sharp and functional as well!
Dave
-
Extremely neat work Dave. A machine to be proud of.
Tweakie.
-
Thank you sir, unfortunately I'm pretty swamped here lately and can't get a large chunk of time to play - >:(
I have a lot to learn with this thing :D
Dave

Ok so my noname controller died as I figured it would as it was used and cheap.... but it got me started into putting together the whole cnc thing so it was worth it. :D
So I bought the G540 and wired it up with a little help from "Crevicereamer" over at the "Zone".
I added 2 of the 270 oz. Keling KL23H276-28-4B steppers and the Keling KL-300-48 48V power supply and she runs like a champ so far. Like a bonehead, I completely forgot to wire in my fuseholder which I will have to do soon-
A couple of pics for you of the front of the controller sporting the logo I drew up which I thought was rather appropriate. ;) And also a quick shot of the back as well.
I'm also including a couple of shots of the newly wired home switches and notice how I did the Z switch on an adjustable stainless rod. This will be very handy.
Thanks,
Dave
-
Thats a really nice job Dave , hey stay tuned in I made a really cool digital RPM guage for the mill , I will post detailed info and pictures sometime tomorrow
-
I love the Gecko Inside logo.
Again very professional looking standard of workmanship.
Tweakie.
-
Thanks, fellas, I appreciate the kind words. :)
Peter, I look forward to seeing how you do it as I'm pretty much an electronics nimrod. This will really add the "cool factor" to any setup 8)
Thanks,
Dave

David here it is uploaded on youtube , sorry if the music is slow the only thing I could find thats 2:40 long , I see that I misspelled Gauge on the writeup in the begining credits...................................(Guage)

Thanks to Tweakie for the hot shoe bubble vial idea, and I've sawn it in 2 and attached one of them to my Z axis adjustable limit switch.
Works perfectly and I get the switch in the perfect position everytime - ;D
I also made an indicator holder for my magnetic based indicator. I just unscrewed the magnetic base and drilled and tapped a block of aluminum and mounted in a T slot on the headstock. Great for those 4 jaw location projects.
Dave
-
Excellent Dave. :) :)
Tweakie.
-
This is amazing. Thank you for the pics and video.
I have a taig that I want to convert to CNC. Do you have a build thread that explains what you had to do? A parts list would be nice.
-
Hello,
Not really a build thread sorry, but the components I used for the electronics were:
-NEMA 23 BIPOLAR STEPPER MOTOR 270 oz-in, ¼” Diameter Shaft with flat KL23H276-28-4B (Dual Shaft) Price: $39
-power supply= The $50 Keling KL-300-48 48V/5A
-Gecko G540 Drives/breakout Board.
Hope that helps-
Dave
-
Thank you. This machine is a pleasure to look at. I spend a lot of time looking at the pics.
Two questions: Any specs on how you set up the ball screw?
And: Did you make all of those brackets and spacers yourself? It looks fantastic.
-
Thanks again for the kind words.
There are quite a few things I still want to do to the lathe as this setup was just to see how much it would take to get the thing running :D
Now that I do in fact have it working well, I plan on doing a number of things such as "beefing" up the Z axis screw which right now is a standard stainless steel screw that I polished up so no burrs or anything like that would eat up the Delrin anti-backlash block. The X axis is pretty much stock and has about .005 backlash so I want to deal with that as well. Not a real big deal on a lathe but tight is good.
Yes, I made all the brackets for everything as this was just a "kit" form Taig Lathe which is really a great deal as it does not take a rocket scientist to get up and running. Keep in mind I have a shop where I made all my brackets so unless you have that at your disposal, I guess it could be pretty tricky to do without.
I highly recommend looking at Nick Carters website (cartertools.com) as he has an amazingly amount of info on the Taig stuff.
Dave
-
An update for my little Taig Lathe.
Finally got my RPM setup up to speed (lol!!) and thought I'd share a couple of pics. Thanks to Arturo (http://www.cnc4pc.com/Store/osc/) and Peter Homann (http://www.homanndesigns.com/store/) for helping me figure out what I needed to do this right.
Also wanted to thank SimonD for his posting of his guide for setting up the Speed control : http://www.machsupport.com/forum/index.php/topic,6707.20.html
I can now, with the flick of a switch, run my motor manually, or through Mach 3 control.
You can also see the index plate I made (one with the many holes in it ;) ) , but I still have to make the spring loaded engaging pin that will allow the spindle to be held in position.
Thanks,
Dave

Love the Gecko Inside logo ;D
Hood

Marris liked it as well :)
Dave
-
I bet he did but also bet he doesnt use it for fear of being sued ;D
Bit curious, what spindle speeds do these wee lathes have?
Hood
-
Dave,
You mentioned about replacing the screws. Ball screws my friend ,and start looking ,since the small ones are hard to come by and they are not cheap if bought new. You may also want to check out Phils screen for the lathe. Guess you'll be threading in a short time.
Let me know how it all works.

Hood
Hood, the original 3/4-16 thread headstock is only recommended at 7000RPM but I've since gotten the ER16 headstock that is "supposedly" good to 12,000 RPM. My aftermarket treadmill motor does 10,000 RPM with no issue, so that should give you an idea of where I'm at.
Here's the website for the original setup: http://www.taigtools.com/mlathe.html
Rich, after looking around, this lathe would just be too much "underkill" for ballscrews as delrin "adjustable" nuts work just fine. I thought they would wear so much more than they have but have been just unbelieveable in their performance on this thing.
Thanks for looking,
Dave
-
Hi Dave,
Are you using a Delrin nut on the cross slide as well? If so did you just copy the original bronze one?
Cheers,
Peter.
-
Sounds good Dave, definitely need the high RPM for the small dias :)
Hood

Hi Dave,

Peter.
Hi Peter,
Yes, but I took it a step further as I've actually screwed the "boss" of the nut, to the crosslide from above (drilled and counterbored through the top of the crosslide. Sorry, no pics of that, but will try to remember to get some in the future.
Thanks,
Dave
-
Hi Dave,
Thanks for the description. I understand and will give it a go.
Cheers,
Peter.

well done
I have the same lathe mine is set up for pool cues
the tool holder on my lathe is loose
i have thought of mounting my lathe on my cnc wood router . i am not ready to tackle that for a while
mikee
-
Thank you Mikee, perhaps you could start a thread showing off your pool cue lathe or your wood router?
Everyone here loves to see what others are building.
Dave
-
well Dave it has been a good day
i got my cnc to cut a circle little flat on the sides i have a little play here and there i will tighten it up hope fully that will make my circle a little more round .
need to get my cnc where it can repeat
i will start getting some pictures together you are going to have to help me post my pics i don't know how to on this site
(my stuff back yard cnc ) but i have very much enjoyed this
i sure didn't know what i would have done without some of the guys in here helping me
taig has a lathe chuck with a large spindle bore out now with a indexer on it that's the one i would like to make my 4 axis with in truth my tail shaft on my taig lathe it is so loose
I'm very interested on how you got your lathe in tolerance
mikee
not much land dam few cattle co.

Hadn't seen that on the site, got a link, and/or a price?

Not sure what you mean by in tolerance?
Thanks,
Dave

my lathe
i dont what it is called but the tool carrier that goes back and forth
if it was a cnc it would be x axis slides parallel with the bed
its ok for replacing tips and ferruls on a pool cue it works great
mikee
