Fourth axis pulse equivalent settings:

The Mach3 system settings:  the pulses for 1  required:

( the motor 1 Circle of pulse number × the drive of subdivision number × reduction ratio) ÷ 360 degrees

 For example, the two-phase 57 motor, the ubdivision number 16, the reduction ratio 50:1

                      (200 × 16 × 50) ÷ 360 = 444.44444444)

Ncstudio system settings: the angle of a pulse walking:

  360 ÷ (the motor 1 Circle of pulse numberr × × the drive of subdivision number × reduction ratio)

 For example: the two-phase 57 motor, the breakdown of the number 16, reduction ratio 50:1

                      360 ÷ (200 × 16 × 50) = 0.00225

X or Y axis instead of the algorithm is:

 Circumference ÷ (the motor 1 Circle of pulse numberr × × the drive of subdivision number × reduction ratio)

 Engraving different sizes of round bars, equivalent needs to be set
