Z axis clicking and going only one direction

[Luca79]

Hi all,

yesterday, I turned on my printer (duetWifi board) and the Z axis stepper started clicking and apparently going only one direction (downwards). The printer was perfectly fine, the only thing I modified was a fan that I have attached (which is working fine). Anything else is working as expected. What should I look into to debug this issue?

Thanks!

In decreasing order of probability, I suspect either bad crimp connection in the cable, a failed driver chip, or a failed motor.

Bad crimp on Z2 Thanks a lot and please accept my best wishes!
