Hey guys
Just started training on an Okuma LC-40 with an OSP 5000 controller.
I was looking for an easy way to make the tool holders go to tool change positions, and i find a reference to a G20 and G21 conde from the list on this page: Okuma Lathe G M codes G-codes M-codes

But I can't seem to find any more info on those.
I've been searching through the manuals for the better part of the day with nothing to show for it.
Does anyone know of them?
