I have been working on my CNC for about three weeks, starting with printing all the parts. Here they are:
I also printed parts to use my angle grinder as a cutoff saw for the conduit:
Here’s my nearly-completed machine. I’ve just gotten the axes moving using the LCD, but I think I need to get a real drive coupler to get the z axis working better.
Still need to get it bolted down in its new home, and then start learning to use the CAM software.
Thanks, Ryan, for making this journey possible for me!

Hmmm. Where are my pictures? I used the img button to link to the pictures on dropbox. They’re in a public folder. How do I make my pictures show up?October 10, 2015 at 4:14 pm #3444
Maybe as attachments?October 10, 2015 at 4:18 pm #3446
Maybe as smaller attachments?

Nice work, it all looks good to me.
I’m almost at the same stage, a couple more prints to do, then play around with the electronics before full assembly.

Note that a regular pipe cutter works on steel conduit. You just have to go around it many times and need strong hands.
I love the grinder chop saw!October 10, 2015 at 11:42 pm #3459
I really could have used the little chop saw print when I was building the 4 head printer. Cut so many pieces I had to get a new hacksaw blade.October 11, 2015 at 2:39 am #3467
Northern Tool has a similar mount for an angle grinder chop saw, but I could never bring myself to spend the $25 or so for something I wouldn’t need very often. Then I saw this: http://www.thingiverse.com/thing:317474. Worked perfect for my application. The clamp I printed was a little large for my harbor freight grinder, but I just wrapped in a strip of rubber pond liner I had laying around. The clamp can be sized to fit, though. Wear safety glasses!October 12, 2015 at 5:33 am #3492
Hi Karltinsly, could you please tell me where I can download the attach you have in your pictures 2015-10-10-15.48.47-Medium.jpg ?
Many thanksOctober 12, 2015 at 7:03 am #3493
Do you mean the angle grinder mount? It’s http://www.thingiverse.com/thing:317474.
If not the grinder mount, what are you referring to?

SUCCESS! I finally got everything ironed out and had my first successful print (with a sharpie in the tool holder). Tomorrow I hope to do my first cut!
Can I embed a video here?

Made my first cuts!October 17, 2015 at 11:35 am #3586
Used a 1/2 inch harbor freight end mill, 15mm/s feedrate, 1mm depth, 65% step over. Next time I do one of these, I will oversize the slot so it can be cut with the 1/2 inch bit and still fit the t-slots, and I’ll also put the two boards together and cut the slots for both at the same time (just set the depth to 31mm). I might also speed it up some – either faster feed rate or deeper cuts. But I shouldn’t need to do this again for awhile.
The only thing left is dressing the bed.
These t-slots are awesome! They take 1/4-20 carriage bolts, which are cheap and readily available. I couldn’t find a 1/4-20 knob with a trapped nut, so I remixed my own. Here’s what I used:October 17, 2015 at 2:36 pm #3588
Nice, added them all to the videos page. Congratulations.October 31, 2015 at 9:06 pm #3938
Meant to be test cuts, but they came out so well, we’ll probably use them! Really liking the carve feature of ESTLCAM. I’ve used a 1/2 inch 90 degree and 1/4 inch 60 degree bit so far. I’ve ordered a set of 10, 15, 20, and 30 degree bits for finer work.
Getting your z-zero correct is key, especially for carving. I find it’s better to be too deep that than not deep enough, so I usually set my zero a few tenths of a mm below the surface.November 1, 2015 at 6:47 am #3941
looks like someone is about to have the machine pay for itself pretty soon. Those signs cleaned up really well. Thanks for the new vid and the inspiration to try the esltcam carve feature.November 1, 2015 at 6:02 pm #3948
The machine paying for itself would be great! I’m a ways from that but working steadily towards it. I also want to try this:

If anyone knows where I can get a good bas relief file of a llama or alpaca, please let me know!
KarlNovember 2, 2015 at 10:02 am #3954
Can you please share a few things? Which dust collector head is that? Are the files available on thingiverse? What OD did your use for the sharpie holder? What cable chain did you use? Printed or purchased?
I recently ordered the carving bits and hope to get them soon.
CurtNovember 2, 2015 at 6:07 pm #3961
Thanks, Curt! The dust collector is the one that PCFlyer created for his spindle. I created an adapter that will mount it to the DW660. You can find more details here: http://www.thingiverse.com/thing:1091450.
The sharpie holder was something I threw together on tinkercad. I’ll try and attach it here.
The cable chain was purchased on Amazon: http://www.amazon.com/gp/product/B00880AVL2?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s00. I ordered two of them. I didn’t want to spend all the time needed to print them, especially because I knew they wouldn’t be as strong and reliable as the molded ones.
KarlNovember 2, 2015 at 6:08 pm #3962
Hmm. Wouldn’t take the .stl file. I’ll try a zip.

Areyou having scaling issues with ESTLCAM? When I take files made in inches from autocad to ESTLCAM as .dxf there is a downscale of who knows what factor. I have ESTLCAM set to import inches and my machine export mm. Not sure, but thought you might have the answer as you are in the US and probably use inches.
Also your setup looks great. You make me want to clean up my workspace.November 6, 2015 at 6:53 am #4022
I use mm, so I have not run into this. Is it importing them wrong or exporting them wrong?
My only suggestion would be to take it off inches and tell it to ask every time on import.November 6, 2015 at 10:24 am #4028
The only scaling issues I had with ESTLCAM was with SVGs out of inkscape, which turned out to be a problem with SVGs. I’ve not had any problems with DXF out of inkscape or visio. I do save with mm as the unit of measure.
Thanks for the compliment on my “clean” shop. Don’t tell anyone, but the camera is pointing at the only tidy spot in my garage!January 21, 2016 at 6:45 am #6169
Not very long or detailed, but here’s a short video of my MPCNC lasing some leather. Worked okay, but I need to spend some more time on it to get the quality of the burn up.January 17, 2017 at 7:31 pm #25201
Almost exactly a year since I last posted in this thread! ‘Bout time to revive it. You know you’ve been around when you find your old post less than 20 threads from the very beginning!
I’m getting close to getting my upgrade finished. The new build has the new middle section (MUCH stiffer! Thanks, Ryan!), the new rollers, a gantry-mounted vacuum shoe (not quite finished yet, but I got the mount on the gantry), and gantry-mounted terminals for the Z axis.
There will be some new electronic bits, too. In addition to the separate button controller, posted somewhere else here on the forums last year, there will be an updated version with more buttons for specialized functions and tool control, and a PID speed-controlled spindle.
I have some other things planned, as well. I’ll post pics as it starts to come together.
As always, thanks Ryan, for a great machine!January 17, 2017 at 7:55 pm #25202
Thanks and glad to see you back at it.January 17, 2017 at 8:18 pm #25203
When you guys post the dimensions of your builds, is that working area?
ZJanuary 18, 2017 at 5:58 am #25217
I can’t speak for everyone, but in my case, yes, it’s the working area.
