Auto Z & Corner Finding Touch Plate


The Avid CNC Auto Z and Corner Finding Touch Plate system allows for quick and precise setting of your tool height and work piece corner/edge location.

Additional instructions for use of the Auto Z and Corner Finding Touch Plate can be found in our Mach4 Users Guide.

Operation Note

The touchplate must be electrically isolated from the machine to function as intended. It cannot be used directly on metal or workholding that has a conductive path to the machine frame.

Software Note

The Avid CNC Mach4 installer provides our version of Mach4, which is configured with full integration for use with the Auto Z and Corner Finding Touch Plate.

If you are using Mach3 CNC controller software, refer to our Mach3 Auto Z and Corner Finding Touch Plate Instructions.
