    Yep, Lee I had one relay per driver with the fault signal driving the relay so a fault on any driver would open that relay which would break my enable circuit which ran in series thru the 4 relays + spindle fault relay. So you are correct, I just replaced the simple logic that the electro-mechanical parts performed with digital.

    Please keep in mind I'm very much a noob when it comes to this electrical and electronic stuff so how do you gents combine these sinking type stepper fault signals?
