Single Z-Motor doesn't move
-
Hope you can see it better on the picture below.
-
@jay_s_uk Yes I tried this as well. Than the motor also doesn't work, however all motors work fine at the other locations/drivers.
-
@Eisbar this looks ok, it was a matter of perspective.
-
@Eisbar please check the backside also, that the elements are soldered correctly, especially the connector socket of Z.
-
If you unplug the motor (while powered off) and then power up and try to move the motor does it give an error?
When and where was the Duet purchased?
-
@Phaedrux there is no error with the motor unplugged, should there be one? It behaves the same as with the motor plugged in, so it shows 'movements' in the dashboard.
It was bought 12-2019 at ReprapWorld.
-
Can you send M98 P"config.g" ?
-
@Phaedrux said in Single Z-Motor doesn't move:
M98 P"config.g"
It shows:
M98 P"config.g" HTTP is enabled on port 80 FTP is disabled TELNET is disabled
-
@JoergS5 the connections seem okay, however I don't known how it should look like:
-
@Eisbar this looks perfect, I could not solder better myself
This is not the reason. -

Unfortunately well out of warranty.
Based on your description and the testing done it does seem like the Z driver has failed.
You can use the E1 driver for Z by remapping if it's free.
-
@Eisbar I saw that Z is immediately homed, I wonder how the Z position can be 50.
Can you please check
G91 G1 H2 Z100
whether the stepper rotates?
And then M122 and check the line for driver 2.Edit: I see you say tool position changes, but stepper doesn't move. So probably a wrong idea from me. But maybe you try anyway.
BTW I wonder why your console says Z endstop is triggered, but in your config you disabled endstops. The G1 H2 command above ignores the endstop status.
-
Post your homeall?
Also, remapping Z to E1 would let us test your current config on a different driver.

I pressed "home Z" and thereafter two times "Z+25", just to check if the motor would move (it didn't).

When I press "Home Z" and thereafter "G91 G1 H2 Z100" the motor also doesn't move, the M122 result is as follow:
"Driver 2: ok, SG min/max 0/0"BTW I wonder why your console says Z endstop is triggered, but in your config you disabled endstops.
Which lines does indicates this?
Thank you for your help so far! -
@Phaedrux that would be very sad, I just used it a few times in only simular configurations and just started with construction of the printer. As I planned to use E1 for an extruder and E0 for the double Y axis, I could not miss the Z-driver. Is the warranty less than a year?
Thank you for your help so far!

Also, remapping Z to E1 would let us test your current config on a different driver.M122 after "home all" with Z-motor at E1 (Driver 4), everything works fine:
Driver 0: standstill, SG min/max 0/244 Driver 1: standstill, SG min/max 0/276 Driver 2: ok, SG min/max not available Driver 3: standstill, SG min/max 0/249 Driver 4: standstill, SG min/max 0/250
M122 after "home all" with Z-motor at Z (Driver 2), Z doesn't rotate:
Driver 0: standstill, SG min/max 0/247 Driver 1: standstill, SG min/max 0/295 Driver 2: ok, SG min/max 0/0 Driver 3: standstill, SG min/max 0/288 Driver 4: standstill, SG min/max not available
I wonder what SG min/max 0/0 means in the last case.
-
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.

xcept that those exact same values work fine when Z is mapped to E1.
sorry, I overlooked that...
