Z-Axis not work
-
Hi,
I have problem whit Z-axsis stepper motors.
I purcase my duetWifi board 20/03/2018 and everything is working great, until yesterday my printer start sound weird when i try go z-home. I noticed that only motion i get z-axis is wierd flutter.
I check wiring and eaven change diffrent steper motors but not get any real motion in z-axsis, xy-motion works normaly.Do you have ideas what can cause this?

It sounds like only one phase of the Z motors is getting energised. Possible causes include:
- Bad crimp connection in the motor cable (most likely)
- Failed stepper driver chip
- Failed motor (least likely)
If your E2 motor output is free, one way to diagnose this is to add this line to config.g before any M906 or M350 commands:
M584 X0 Y1 Z2:4 E3
Then you can connect one Z motor to the Z connector (with 2 jumpers fitted to the other Z motor connector) and the other motor connected to the E1 connector. This will help you diagnose whether the cable or the driver is faulty.

Okay, problem is solved it was motor cable and actually both cable.
I dont understood why both cable can die same day, anyway this is very cheap repair thank you.
