Single Z-Motor doesn't move
-
Stallguard values. Not sure why it would be 0/0
-
@Eisbar warranty depends on the country, in germany it is 2 years. The first half year without prove, after that you must prove that you didn't damage it. (Obvious damage voids waranty of course)
But I doubt that the board is defect.
SG and immediate endstop trigger could be because of your strange config settings. M566 and M201 are very low for Z, could you try higher values in the range of X and Y and try to move Z again? -

Except that those exact same values work fine when Z is mapped to E1.

sorry, I overlooked that...

For the sake of completeness, move over the X motor to driver 2 and remap the X axis. If X stops working we can safely say that driver 2 has failed since we've shown that the same config and motor work on another driver already.
-
@Phaedrux just did:
M584 X2 Y1:3 Z4
the X-motor doesn't move and Z works fine. Still: "Driver 2: ok, SG min/max 0/0"

Please run the following commands to check that the configuration is correct. It's not unknown for config.g to contain non-printing characters so that the configuration is not as intended:
M584
M906
M913
M569 P2
M350If it all looks ok, send the following:
M906 Z1000 G91 G1 H2 Z100
Does the Z motor vibrate at all when you send G91 G1 H2 Z100 ?

The results are as follow:

Everything looks ok in the console, however the motor doesn't rotate (also no vibration). The shaft of the motor can be rotated without any resistance, so there is no current.

Thanks for the additional testing, but I think we're still at this point.
