I really need some help. I might have been able to figure this if I didn't have to go back and forth between metric and imperial measures.
I am trying to figure:
steps per mm = steps per rev * microsteps / mm per rev

My motor is nema 23 and 200 full steps per rev
I have a cnc=shield with jumpers set to 1/32 (I think) M0, M1 and M2 are high
Leadscrew is 5/16 -18

Any guidance would be greatly appreciated.
