There are a few options to use for offsets. We use G43.3 and G54.2. They do very different things. I just posted questions about this not too long ago. I am learning as well. I will tell you this, call your builder or dealer. Along with different ways of doing it, builders may have parameters set up slightly different. We almost had a collision because a parameter was set differently from on machine to another here. Basically a physical movement to cancel or activate an offset almost got us.
