Since Axis takes care of all this mumbo jumbo with the touchoff button, I have not used the G10 in a long time. My notes from back then definitely say that a G10 L2 was relative to current position. What I have there says that if you want the current Y position in the G55 system to be Y=5.0, you would give this command : G10 L2 P2 Y -5.0
The description in the user manual is almost completely incomprehensible. G10 L20 makes a little bit of sense, G10 L2 makes no sense at all. Everything has to be referenced to the machine coordinate system at the lowest level. I have no idea what the "origin" means. Is it a direct offset added to the machine coordinate system? Not at all clear from the description. But, I never even want to know about the machine coordinate system. The only thing that makes sense when setting up is where the machine is NOW, because I can measure from that.
