Not built into Mach. It must be written as a macro by the builder or user. G76, G87 and tool changers need it.
Verify on your machine. This entry could not be fully checked against the maker manual. Check your machine manual before you run it.

How it works
Depends on the macro.
Example program

T4 M6 (BORING BAR)
G43 H4 Z1.0 (LENGTH OFFSET)

The full 6-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- If the machine cannot orient, the Mach4 guide suggests an M19 macro that stops the spindle and does M0 so you can turn it by hand.
- Check what your M19 macro does before a G76 or G87 runs it.
