While it's certainly always possible theres a fault in the hardware, I find 9 times out of 10 it's operator error and I've just done something silly or overlooked something. Do some investigating with a multimeter and you may well find it's shorted or not making it all the way to the motion board input.


I've found a schematic for your driver board - my assumption was correct... you will want to set the jumper to the second from last set of pins to allow it to use 2.0 Amps (has 2A next to the pins). That would explain your motors being so pathetic as they were only getting half an amp. You can also see the dip switch settings to set microstepping which will give you smoother motion. You will need to then adjust steps per unit to match however.
