Paw,
There is a good chance you connected the stepper wires (or one of them) incorrectly. The bipolar steppers you are using have two separate windings which can be checked with a multimeter (or other continuity checker).
One pair of wires is A - A# and the other pair is B - B# now it doesn't matter which way round the A's or the B's go but you must not get them mixed. (I have learn't that with stuff from China you cannot rely on the colour coding of wires being correct you have to check them with a meter just to be sure).
Hope this helps,
Tweakie.
