Single Z-Motor doesn't move
-
Hi,
I have a stepper motor connect to Drive 2, together with two jumpers at the ZB position. However, the motor doesn't rotate when I give a commant via the webControl. The tool position and speed in the webControl dashboard do change. I also have connected the motor to the drive 4 (M584 X0 Y1 Z4 E3 in config file below) and than it does work. The same type stepper motors connected to X and Y work fine as well. The Z-motor is not connected to a spindle yet, so the load is zero.
I have checked the resistance over the ZB jumpers, which is non.
Anyone an idea what could be wrong?
The config file is as follow:

Can you post a photo of how you have it wired?
Do you get any error messages in the console when trying to move it?
-
There are no error messages in the console, the dashboard just shows the movement.
Wiring: 4 stepper motors and 2 limit switches (X and Y)
-
@Eisbar have you tried moving a known working motor (either X or y) to z to rule out a motor/wiring issue?
-
@Eisbar this here looks very strange for me:
at the Z driver right upper corner of the driver chip, can you make zoomed image please?As if the resistor is displaced.
-
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. -
@Eisbar said in Single Z-Motor doesn't move:

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.

@JoergS5 said in Single Z-Motor doesn't move:
I saw that Z is immediately homed, I wonder how the Z position can be 50.
I pressed "home Z" and thereafter two times "Z+25", just to check if the motor would move (it didn't).
Can you please check
G91 G1 H2 Z100
whether the stepper rotates?
And then M122 and check the line for driver 2.
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!
