What belt did you use for the Z axis and who did you get it from? I thought I saved a link a couple months ago for a supplier but now I can't find it. I went to SDP website but I can't find anything there that'll work for me. I see that McMaster Carr has a 77" belt but wanted to check with you first. Maybe I can do better.

I need a belt from say 70" to 90" depending on how far apart I want to spread the lift plate mounts.

Thanks again
Bob T.

I used this one from SDP: A 6Z16-913025

Single Sided .080" (MXL) 913 0.25 Neoprene Fiberglass 73.04 length

If I remember correctly, the length was based on what they had in stock!

Macintosh Quadra 950

My CNC router's drive board and power supply live in an old Macintosh IIci case. That case was a great design.

My final optics and nozzle are sort of a hybrid. I use a combination of the LO 18~20mm Focus lens Mount < to hold the mirror and 18~20mm Laser head w/ air assist <> to give me the lens mount and air assist nozzle. This part by itself won't fit properly in the plate, hence the mash up.

I was never happy with the fact that the nozzle was so far away from the work piece with the 50.8mm lens, not to mention potentially loosing power because the beam was still wide before it go to the waist. So I made on the 3D printer an extension to it. It's available here if anyone wants it: ... ension.stl

Printed in ABS which should be ok unless my alignment is way off. If someday I have a metal lathe, I'll turn one (anyone want to do one?)

I saw it on an older buildlog, but I can't remember who came up with the idea first as I've read so many people's posts while working on mine.


Hey pourcirm,

I love this idea!
Where did you get the stand offs if you don't mind me asking?

Hey Techbuilder,

I actually had them in my spare parts box from building my ShapeOko, but I think I originally got them from McMaster Carr. They're just metal standoffs, pretty cheap and easy. Mine are an inch and a half tall which worked out perfectly for me.

Perfect! I took your picture into solid works and measured my stepper to get a base and came up with 1.500 inches as well.
I then ordered these on amazon ... UTF8&psc=1

I wasn't completely sure it was correct since your stepper could of been a different length but looks like I got lucky

Hey Scott I purchased the pro mounts as well from light object and have caused me nothing but pain with getting it to work correctly
last thing I've run into is the laser head is about a 1/2" to short. Did you make a spacer for the head or how about did you get by that issue?

Hi. My picture is wrong. You have to take the black pro head, not the plain/silver one. The black head has its entry hole higher up.

You have a choice then, if you want the lens further down then you can remove the threaded insert to the black head and put the silver one in. Or you can use it as is. I'm not sure yet which is better.

edit: I just tried both. I find I like using the plain silver piece better simply because it's less likely I'll rotate the head accidentally when I remove the lens for cleaning. So it's black head, silver threaded, black nozzle.

Then as I had previously written, I made an extension out of plastic (3D printed) to move the actual nozzle down closer to the work.

Hey Scott,

i really would love to get the code for the arduino sub subsystem. I am still in the beginning but i have some experience with arduinos and would love to work on that subsystem.

Furthermore i would like to ask you regarding some details because your build looks like you really know what you are doing:

1. What drivers and steppers did you get?
2. Which power supply did you use (for steppers and the rest)
3. What i did not find any information about yet: What wires did you use for the connections between power and awc 608 and all the drivers?

thanks a lot!
