CES,
I once helped a person with one of those Chinese boards. The documentation was bad. All the pinputs were wrong.
After fooling around like yourself for a "long time" we got one axis to work. Now do you know how many combinations are needed to
try to figure out all the rest? Loooooong story short, the kid figured it out by going thru a matrix, how many hours he spent I do not know.
If it was me I would have stuck that lousy Chinese dirver board where it belonged .....right in the trash can along with the Chinese documentation that came with it.
Sorry for your troubles, but a lesson learned can be a positive, namely....sometimes one gets what they pay for.
RICH
