OK. It sounds like the ASIC is working correctly. Do
this look like
stepper drive waveforms (3 similar signals with a phase offset between

As far as I can tell, although I've never worked with steppers before.
Is this with the motor connected?
Yes
If you're getting square waves at the driver
collectors with the motor
connected then either the motor is faulty (but you've board-swapped
between the 2 drives so you know it's OK), or there's an open
connection somewhere.
I checked the connections. Maybe there's a bad diode in there somewhere?
Any other ideas?
Thanks,
