There is a Yahoo group for this type of machine. I do have one myself, but converted it to WelTurn. Mine was a series 2. I think the series 3 is actually a series 4. As in you have a few more M codes and can do partial arcs or circular functions. I think a few on the EMCO CNC Yahoo board can help you out if no one here can. Some are even using some of the CAM packages for programing them.
