The amps are probably usable, unless they are the part that keep failing. The amps _probably_ take an analogue voltage signal from the controller. A rough wiring diagram would help. An oscilloscope on the control wiring when running a program would show what the protocol was. I think it is unlikely to be PWM, it will definitely not be step and direction. I see 5 large wires to the servo amps, which is one more than I expected.... I also don't see any control signal wiring. If they are analogue-control amps and brushed DC servos then it is a very simple conversion, and will require only a PC, LinuxCNC and an interface board.
