Scott... if its got any form of ballscrews and stepper or servo drive it can be retrofitted. Software products like Mach3 (arguably the mainstay CNC controller product for hobby and small businesses, although there are others), while not having the complexity of a Fanuc controller, can deliver the goods, its just a different way of working... often more design/pc based than CNC programming on the machine itself.

While many of our members here are hobbyists there are just as many who run small businesses (not all engineering or CNC related). And your other experience is equally valuable. We look forward to you imparting it as and when!
