The spindle uses ER25 collets. These eventually wear out, so check before using them. Collets are a durable expendable.

=== Lack of True E-Stop ===
 
=== Lack of True E-Stop ===
 
As shipped, the ShopBot PRS does not support an Emergency Stop. This could be hacked, but it runs the risk of damaging the machine if engaged in a non-emergency situation. Suggested solution: Installing a 10A double pole 24V coil DIN mount relay, and powering the coil via the 24V supply through a normally closed E-Stop button. One pole will disconnect the 63V stepper motor current. One pole will break the control signal that enables the VFD and will cause the VFD to brake to a stop.

=== Automatic Dust Collection ===

The ShopBot has +5V TTL outputs that could be used to trigger automatic dust collection (when the spindle goes live) and/or a warning light (when the gantry is enabled to move.)
