I hit reply too fast. Deleted the message - sorry to any mail folks
for the repeat.

That motor draws too much current. 2.5A is the A3977's limit.

I could also use a unipolar stepper, I believe if you run it as
bipolar you double the voltage rating and halve the current. So 2V
3A unipolar becomes 4V 1.5A when run as bipolar. errr, at least I
think thats the way it works.
