The following document demonstrates how to recover from a tool that is lodged in material or stuck on
top of the Z Origin Sensor when equipped with the Automatic Tool Changer. If the machine enters an
emergency stop condition and needs to be restarted, the tool will need to be released. If the tool is
lodged in material or sitting on top of the Z-0 Sensor when it tries to release the tool, it will not function
as the tool needs a little clearance to be safely removed from the ATC Spindle. Please follow the below
instructions to recover.
1. Enter the machines service mode by pressing all top 3 keys on the Handy Panel as you turn the
machine on.
2. Select Z-Brake Check and press Enter. Once the Z-Brake is released, the Z-Axis will be free to
be moved by hand as the X&Y axis are normally when the power is turned off.
