Fourth axis pulse equivalent setting

Basic parameters setting:
Pulse for 1 rotating degree(Pulse for 1 circle of motor shaft * driver subdivision) / circumference.

For example, two-phase motor, 8 subdivision, reduction ratio 20, (200 * 8 * 20 = 32000)

1. Weaver system settings according to the length of the chart or the length of the calculation
(Perimeter 100 mm) / 32000 = 0.003125 (pulse)

2.Mach3 set by the angle: 360 degrees a circle
32000 / 360 (degrees) = 88.88888888 (pulse)

3. Weihong system settings: 360 degrees a circle
360 (degrees) / 32000 = 0.01125 (pulse)

4.Mach3 Set by graph length or perimeter
32000 / (perimeter 125.6 mm) = 254.777 (pulse)
