G30 Positioning to home position
Okuma OSP G-code · Mill
Sends the named axes to a stored home position, picked by number with P. Okuma programs use it before tool change or at the end of the program.
Verify on your machine. This entry could not be fully checked against the maker manual. Check your machine manual before you run it.

The full 6-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Okuma does not use G28 for this. G30 with P picks which stored position.
- Clear the part with Z first if the home position is low.
