Which would likely indicate that your motors are fine and it's something further on up the chain. Have you double checked that your wiring's correct..? Yeah, a silly question but it's the silly things that often catch you out. Came across this vid on YouTube, guy puts his issues down to a burned out stepper controller (driver?). Are your drivers getting enough juice?

Anyway, just a couple of ideas - but like I say, don't overlook having done something silly. Check and double check...
