Fanuc G-code · Mill and lathe

Addresses

|---|---|
P | Program number of the macro |
L | Number of repeats per call |
A to Z | Arguments passed as local variables |
How it works
Modal, group 12. Cancel with G67.
Example program
G66 P9020 Z-.25 R.1 F10. (MACRO AT EACH POSITION)
G00 X1. Y1. (CALL AT HOLE 1)
X2. (CALL AT HOLE 2)
G67 (CANCEL MODAL CALL)
G00 X1. Y1. (CALL AT HOLE 1)
X2. (CALL AT HOLE 2)
G67 (CANCEL MODAL CALL)
Example is in inch. Check offsets and clearances first.
Watch out for
- The macro is called after each block with axis motion, not on blocks without motion.
- Always cancel with G67 before moving on, or the macro runs at every later move.
