@scttnlsn - In this case, I did use a mill to cut the slides, notice this machine is a V2 and now we have half a dozen up cnc mills up here at the shop. If you can find access to a mill that would be great to start with UHMW slides but not required. The very first micromill that my friend and I built used PLA 3D printed slides. You will have to really check your tolerances on your 3D printer and I remember it took a lot of delicate hand sanding to get the slides to fit perfectly without slop. They will hold up long enough for you to mill lots of slides.

@maddash1337 - The limits of travel are about 150x150x125 but after you get the spindle and a fixture in place it is reduced to about 100x100x100. And the parts list is published. Its the file that has BOM (bill of materials) in the name. We have published pictures of it cutting a variety of materials, including a chunk of aluminum. I also use them to cut filament shafts from a steel rod. It is a blast building these little work horses. Enjoy!

Did you use an existing mill to cut the UHMW sliders? Do you think printing those parts in PLA work as a temporary step? Curious if you tried other materials for the sliders.

Do you have some information about the "build size" ... or however it is called? Is it able to mill aluminium, steel - where is the limit?

I think I gonna build one - as soon you release the full part list.

Thank you very much for your amazing work :-D

The parts list is in the project downloadable files. It's called, "CNC_BOM" or something like that.
