Re: motor gearing and leadscrew torque

Check post Message 43436 for the torque stuff. (thanks you Les)
or search this list for leadscrew and check out the stuff over the
last month.

regarding speed, stepper steps from a good driver will run 8hertz or
8,000 steps a second. for a 0.9 deg, 400 steps per rev, 20 rev per
second times 60, you are looking at 1,200 RPM of the stepper.

if you are microstepping, then that is 120 RPM


Master5 can do the 8hz.
