Finally getting somewhere

[m.marino]

Oh one other item,

I am having a devil of a time figuring out the reduction from the stepper motor on the 4th axis the gear on the stepper has 37 teeth and the gear on the axial has 60 teeth using a micro stepper set at 800 steps per 1.8° of movement. So working on it and would be very thankful for anyone who could help me muddle through the math (worked the normal formulas at least 4 times each and still not getting good results).

so for each rotation of the stepper the chuck will turn 37/60 revs.

Do you mean 8 microsteps per stepper 'step of 1.8deg? If so thats 8 * 200 = 1600 steps per rev so for each step the chuck turns 37/60 * 360/1600 degrees = 0.13875degrees
