Error: short-to-ground reported by driver(s) 2

[eric22m]

I transferred to a duet WiFi 2 a few months ago and I have been loving it. After setup, my printer has worked flawlessly. But today when I attempted to home the machine I was greeted with a short-to-ground error. The motors make a sound just like its binding. I have narrowed the issue to my z stepper motors. What is the issue and how can I fix it. I have attached a screenshot of the error:

[Veti]

first check the wiring and crimps.
use a multimeter to measure the the resistance of each wire.
then measure the resistance of each phase of the motor.

@veti How would I measure each phase of the stepper motor?

[Veti]

measure the resistance between the pin/cable of red/blue and green/black

It could be faulty wiring, a faulty stepper driver chip, or a faulty motor. Is there any sign of damage to the Z driver chip?

[eric22m]

@dc42 I tried to use a completely new stepper with different wiring as well but I still get the same error. The stepper driver looks completely fine.

@veti I checked the resistance of the wires and everything seems normal.

[Veti]

reconfigure the E1 output to be Z to be sure.

I believe the issue is the stepper driver. I have contacted the company I bought it from and they have agreed to send me a new board. Thank you all for your help.
