My latest and simplest sketchup design. Animated using proper animation for Jeans viewing pleasure. Using the specs off the nema 23 motors from the link Bijil provided and using 2 on the X axis as Peter suggested…

I like the plexiglass. You may be missing space for the couplers on the Steppers and shafts.
Any thoughts about end stops?
@Marcus_Wolschon I though about that, but without actual parts in hand it’s hard to work everything in. The whole things wood so even if I did build it before I had parts, adjustments wouldn’t be too hard I don’t think. I figures on using some aluminum angle for end stops…
Thanks for thinking of me. Yes, I really enjoyed your animation.
What kind of linear bearings are you using?
16mm linear slide guide shaft SBR16-150/420/420mm 6 rails+12 SBR16UU blocks

@Peter_Fouche1 Perhaps, but still a good thought to keep in mind. Plus the size is dictated by the length of the guide shafts. Would much rather go with the 300/600/750mm kit instead of this 150/420/420mm one. Or even bigger.
Looking at @Daniel_Would setup makes me think those nema 23’s can handle much more, or that I could go with smaller motors.
I assume that like me, the goal of every CNC is to aid in building the next bigger n better one… ;p
But my biggest concern is what to do on Ballscrew setup. There’s no way I’m spending what they all seem to want for these things. Wondering about size n thread count on a threaded rod type setup. And of course bearings for them…
This one’s is 270x270 (as highlighted by the center panel) with 62.5mm travel on the Z axis…
