M140 (FULL RETRACT TO LIMIT)

Example is in inch. Check offsets and clearances first.
Watch out for
- Use before an index on a tilted plane so the tool does not drag across the part.
- A negative L moves toward the part.
Machine builders set many M codes, and they change by model and options. Check the M code list for your machine.
