Okay the first thing you should know is never unplug an energized stepper motor. The feedback from the coils can ruin your stepper driver. I wonder if you have the coils wired up correctly? If while having the motor disconnected you short the two coil wires together the motor should become hard to turn. If you have a matching pair. If you short the second set the motor will be even harder to turn. Or it could be your power ref is turned down to low. The driver could be damaged.
