My coworker is helping a friend of his with a T-Line Horizontal 2 pallet machine. The issue he is trying to figure out now is how to set the coordinate offset/part zero. He was wanting to know if M2 reset it? He was able to get it to drill and tap a hole but when it indexed around to the other side the drill was about 5 inches off. He has been trying to figure this machine out on his own and seems to be getting most of it.

The control is a Acromatic 950MC and the machine was built in the late 80's

Thanks for any help and I will pass it on to him.
