John email me with your configs and what connectons are you using on the stepper drives , as these have optos , do you have the + positive side of pulse and direction and enable tied to 5+ with the neg sides connected to the 7i76 use STEP0- PIN2 and DIR0- the enable lines can all go together to a single amplifier enable pin put for now leave it disconnected
