Just another thought about the motor reverse - try altering the ports and pins - make the reverse active low - (or high if it is low already) and see if this alters your motor running. ( It shouldn't really, but you never know).
The other thing to do is check the voltage on your CNC board on the reverse pin and see if it alters when you reverse the motor, it should do. You won't see full voltage because they are only pulses, but you should see a change.
If you have a hi/lo/pulse detector for computer work then use this, it gives a lot more reliable information.
