I see some other possible issues as I read the manual. G81 doesn't have a "P" parameter. It only accepts R as release plane and the Z should be a negative...

You have to call a tool length change with G43 Px with x being the tool number. G82 is not a recognized command. Just call the G81 and give the X and Y of each...
