Motors still not spinning, but checking the direction pins at the drivers themselves show that they are changing from 0 to 5V depending on increment/decrement. Is there a good layout of which pins on the parallel correspond to which functions?
Although if the dir pins are changing when jogging shouldn't the motors be turning?
Step pins on jogging change from 5V to slightly over or slightly under 5V depending on direction. B coils have a differential of -0.8V (constant while jogging), A coils have 1.4V (constant).
