All, Thanks for all the help and posts on this board. So if I am building at 1000mm x-axis with a dual 1000mm y-axis I plan on using openbuild nema 23 with 345oz of torque, sku# 596. But for the z-axis any reason why I can not use openbuild nema 23 with 175oz sku # 518, since the Z-axis should not have that torque. Or am a missing something? With my countless hours of reading and watch youtube videos. I discovered the tinyg vs the Xpro V3 controller a difference with 1/8 vs 1/32 stepping. So any thoughts on differences with this 1/8 vs 1/32 limitations.
