Removing and Replacing a Spindle
This guide uses the SmartBench Precision as an example, which includes a grey speed control cable as well as the power cable. You can ignore references to this wire if you have the Standard version of SmartBench.
In order to change the spindle, you will want to move the Z head closer to the X0(X home) position for easier access. To do this, use the arrows highlighted below to move the Z head along the X axis.
You will need:
6mm hex driver (this is provided in your toolkit)
Step 1:
Disconnect the spindle power cable and grey wire
Step 2:
To access the spindle cage bolt, you may need to lower/raise the spindle cage to align with the holes in the protection window.
To do this, use the arrows highlighted below:
Insert the 6mm hex driver into the spindle cage bolt and rotate left to loosen the bolt. Then lift your spindle out of the top of the cage. The spindle may need to be rotated in order to remove it.
Step 3:
Once you have changed your router bit (for our guide to this, see: ), carefully replace your spindle in the cage with the spindle switch facing forward.
Step 4:
Reconnect the cables ensuring the speed control wire is secured back into the recess.
Step 5:
Tighten the spindle cage bolt by turning to the right.
