M20, M21, M22, M26 — Move To Clear Point
These commands are similar to M0, M1, M2, M6 respectively except the X and/or Y axes automatically move to the
clear point and the Z-axis returns to the home position. The clear point is set by the operator in SETUP such that the
part or fixture is cleared and the tool can be easily removed. In moving to the clear point first, the quill retracts, then XY
motion occurs.
NOTE
The system must be in the Rapid Traverse mode (G0) when Move To Clear Point occurs. No X, Y or Z data should be
programmed with a Move To Clear Point M-code.
Example: N230G0T3M26; Tool Change at Clear Point
