How to load into the Z Head correctly

How to load your SC0/1 spindle motor into the Z Head

Make sure that the spindle motor switch is in the On position.

 

A: Spindle motor switch


 

Load the spindle motor into the Z Head from the top. Ensure that the switch is facing straight forward towards the home end of the X Upper Beam else the spindle motor will foul the cage and won’t fit.

Take care not to hit the cutter as the sharp edges are delicate.

The spindle motor has air ducts on each side to allow for air to pass through to cool the internals during use as shown below.



 


 

With the spindle motor inserted into the Z Head, rotate the spindle motor anti clockwise so the switch is in line with the front edge of the aluminium pillar to maximise airflow for cooling.

 

Air flow out of the spindle: A

 

Once the spindle motor is in place in the Z Head, tighten the clamping bolt. Do not over-tighten, since this will over-compress the bearings in the spindle:

  • If using the supplied T driver, tighten until you feel resistance then apply an additional 90° maximum.

  • If using a torque wrench, apply a maximum of 7Nm.

 

Plug the power and signal cables back into the Z Head.

B: Power cable

C: Signal cable
