@dc42 said in Stepper Driver functioning improperly, warranty claim?:
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.
Can you please update, is this a valid warranty claim?
Thank you.
