I'm looking at a used Taig Mill which has a SuperTech CNC conversion. It comes with SuperCam (the DOS version).
What controller did these come with?
How can I identify if the controller uses a pulse and direction scheme, or if it is running using an older control scheme that wouldn't be compatible with Mach3?
What drivers and steppers were these machines typically sold with in the early 2000s?
I'm trying to determine if modernizing the machine would be as simple as a new controller board, or if I'd be looking at a new controller, drivers, and steppers (so basically I'd just be buying a 2019CR).
In the photos the motors appear to have NEMA23 mounts and are octagonal. The controller looks like the EMC-XYZ-MUBX. The seller does not believe that it is Mach3 compatible.
