Stepper Driver functioning improperly, warranty claim?
-
Hello,
We have been using a Duet Ethernet for a custom 3d printer application for a few weeks now with great results until now.
Our z-axis stepper has started either outputting a back and forth motion or just not functioning at all. We checked all the wiring and even tried multiple stepper motors with similar results.
Is this something that is covered under a warranty claim?
The board was purchased through Filastruder, they informed us that we need approval from Duet3D before anything can be filed.
Thanks,
Nathan

To verify that the problem lies with the stepper motor driver, try connecting the Z motor to a different driver. For example, if you don't already have a M584 command in config.g and your E1 motor output is free, add this command to config.g (before any M350 or M906 commands):
M584 X0 Y1 Z4 E3
and then connect the Z motor to the E1 motor output instead of the Z motor output. You may also need to change the motor direction in the M569 P4 command (set it the same as in the M569 P2 command).
If that fixes it, then the problem is likely to be a blown stepper driver, and it will be replaced under warranty.

I've attempted as you've requested and verified that the z stepper motor functions properly on another output. I've also verified that the stepper driver is faulty by testing another stepper motor on the that driver with the same result.

Can you please update, is this a valid warranty claim?
Thank you.

Yes, I'm happy to approve a warranty replacement.
