The significant difference between the PC-software based systems and the Motion Cards like Galil, is with the Motion card, the servo loop is closed back to the controller, so the control constantly knows the status of the servo loop .
There is a fairly long learning curve, and the actual implementation/installation of Camsoft etc, is generally longer than a pre-engineered system like Mitsubishi, Fagor or Fanuc.
Systems like Mach etc, allow the hobbyist access CNC at an economical level.
