Replacing the Spindle Fuse

On several occasions, the spindle fuse has blown. If this is the case, there will be an audible relay noise clicking in the control box when the spindle is turned on through G-Code but nothing will happen at the spindle.

The procedure to replace the fuse is fairly simple. In the video shown below the fuse used is: T3.15A 250V.

Fuses are kept upstairs in the workshop, see the set of narrow wooden draws on the floor to the right side of the wall of boxes.

Note: Ensure the control box is completely disconnected from mains power before working on the internals
