Engraving machine 4th axis (A axis, Rotational Axis, CNC dividing head) gapless harmonic reducer gearbox

Chuck type: K11-65mm or K12-65mm

Center height: 44mm

Total height: 85mm

Angle: 0.3°/ step

Reducing ratio:4:1(belt deceleration mode)

Stepper motor: Nema17 2-phase 4 wire

Accessories: Set of Anti-claw and wrenches

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 6:1

(200 x 16 x 6) / 360=53.3333)

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 6:1

360 / (200 x 16 x 6) =0.01875
