Product Description

This product ships directly from supplier. Due to Covid-19, the delivery time can be slightly longer and up to 8 days.
You can attach a 4th axis to your machine. Raw machines have one port available. We do not have support for this product, you have to look for a solution yourself. With a rotating shaft you can mill round objects such as chair legs etc. Keep in mind that you also need an extra Drive module and possibly more power for the extra motor

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

Chuck type: K11-80 (3 jaw centering chuck)
Center height: 65mm
Total height: 115mm
Angle: 0.3°/ step
Gear box output shaft diameter: 20mm
Reducing ratio: 6:1
Stepper motor: Nema23 57mm 3A 2-phase 4 wire

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
