Change from Pathpilot to Masso controller, possible?

Somebody can help me understand how the turret work as far as indexing, how does the controller know what tool is in position to machine a part. Does it have a switch for each tool or some kind of encoder. If somebody has the schematic of the board, this would help me a lot. Thanks.

For the OD turn it would be nice to have a beginning chamber option. The parting op had that option. The mazaak i run at work is that way. I k ow this is no mazak but it would be nice. I do 2 od turn ops and then do a profile with chamber and relief for the shoulder. It works but would be nice to have those options.
