Details:
1. The first reference point coordinates are set based on the X, Z, and settings in MCM
parameter G28.
2. The X, Z values in this format are not used. They only indicate which axis is to return to
the reference point. Therefore, regardless of whether G28 is an independent block or
contains X, Z commands simultaneously, the tools return to the reference point based on
the X, Z settings of the MCM parameter.
3. Prior to executing G28, tool offset must be disabled.
3.12 Return From Reference Position, G29
Functions and Purposes:
After returning to the reference point by executing G28, use this (G29) command to
return to the previous target point prior to G28.
