Gotcha, slowly wrapping my head around it all. I would guess those 180watt motors (they also have a 200watt and 400watt variant) would probably work well enough for the Y and Z axes with their 16mm ball screws, or would it be a good idea to look for more power for all three? Once I get the bits and pieces a little more together I’ll take a few more pictures and sketch up some options for the X axis screw.

Also need to check the mounting holes as milled into the machine - I think they’re NEMA23, which fits the 180w but not the 200 or 400w models of those drives (6060 frame sizes). The 400w is also higher voltage (48 vs 36 nominal).
