What opto do you have? are they both the same type of BOBs? Have you tried wiring direct to the PP?

I just had a look at you steps/deg calculation and I think there may be an error.
Wiith 1.8deg stepper it is 200 steps per 360 deg. With micro stepping it should be 2000 steps per 360 deg or 5.55555steps/deg
