Table Top Installation & Calibration¶

The instructions and images in this section show installation on the machine's crossmember extrusion. For mounting on a spoil board, it is recommended to cut a pocket in the spoil board for the rotary frame to sit in. Use a pocket width of 355mm (14") and depth of 5mm (3/16"). Position the rotary frame flush against one edge of the pocket.

The following video can be used as a complimentary guide during installation and calibration of your Avid CNC rotary axis.
