    looking for a controller for Mach 3/4 with interface for stepper motors, tool changer

    I have a Shizouka mill that originally had a Bandit controller and servo drives. I replaced the Bandit with Mach 3 and a Vital Systems interface. That worked fine until one of the encoders died. I am not an active maching business so because of the cost to repair the encoder, the mill has not been used for many years. It is now less expensive to replace all the drives with steppers than repair the one encoder. Unfortunately, the Vital Systems interface will not work with steppers. One that will is extremely expensive. I need an interface between Mach 3 (possibly 4) and the mill that can control limit switches, a tool changer, a VFD, etc.

    Any suggestion the forum might have will be appreciated.

    ...why not just replace the Encoder with a new one. They are about 150usd each.

    These encoders are built into the servos. Lowest price I got to repair...$750. I would then still have 40 year old servos and servo drivers. For $790 I bought all new steppers and stepper drivers. Seemed like a good choice at the time.

    I have replaced many encoders, both shaft type and through hole, generally is is not that a difficult issue?
    The only time it really gets tricky is with BLDC motors where the encoders also have commutation tracks that have to be aligned using a double beam 'scope.
    But not difficult if you have access to one.
