Thanks for the tips! Is there any real downside to a pitch of 10mm vs 20 or 25? If I’ve understood it right, it means less torque if I’m using servos at a given speed, vs running higher rotations and getting more power at the cost of lower top speeds. My assumption was that unwound not be hitting top speeds (in terms of motor rotations) with either solution. I was looking at these motors for all three axes:

I had seen cross braces for the gantry i. Other builds, will see about adding one, thanks! It can double as a mounting spot for the energy chain as well. Any suggestions as to dimensions? Intuitively I would prefer something like 20mm thick 100mm wide solid bar, drilled and tapped every 50-60mm, to a piece of extrusion. Or is something thicker or wider a wiser choice?
