The fourth axis parameter settings:

Mach3 system settings: the pulses required for 1°

(Motor 1 lap pulses x Driver fine fraction x Reduction ratio) ÷ 360°

For example: 57mm 2- phase stepper motor, fine fraction of 16, reduction ratio 100:1

(200 x 16 x 100) / 360=888.88888888)

Weihong system settings: 1 pulse along the angle 

360°/(Motor 1 lap pulses x Driver fine fraction x Reduction ratio)

For example: 57mm 2- phase stepper motor, fine fraction of 16, reduction ratio 100:1

360 / (200 x 16 x 100) =0.001125
