problem with switching to seperate Z axis drivers
-
I think you're going to need to add the second Z driver to your M906 command because right now I think it may be using the motor current for the extruder.
Try M906 X900 Y1200 Z900:900 E700 I50

i tried as you suggested, the issue remains the same, it just makes a bunch of noise and does not turn.
Using a different motor makes the same noise with no spinning of the motors.one thing i noticed is that after i tried to move the Z axis one side is resisting movement while the other side is spinning easily.
i dont know what changed to cause this behaviour, i only took the plug from the second Z connection and placed it onto the E1 connection and then used the jumpers on the Z connection.
besides that i updated the firmware but i dont think that would make a difference?jeff

That's not needed, but the M906 command does need to come after the M584 command in config.g (which it already is).

i plugged the X axis into the z motor to confirm the motors are ok and this works as it should rulling out defect motors.
Can you describe your test a little more? Which motor did you connect to which driver?

the X axis motor is close to the left Z axis motor, so i switched the connectors around so an input on the X axis would result into a movement on the Z axis and visa versa.
The result is when i try to move the X axis via the webpage it moves up and down without any issue. no vibration and no weird noises.
On the other hand the X axis then displays the same issue where it vibrates but does not move.jeff

What happens if you connect the Z motors back to the Za and Zb connectors, then connect the X motor to the E1 connector, and change the M584 command to:
M584 X4 Y1 Z2 E3
Does the X axis move normally?

i just tried connecting driver E1 to the X axis and it has the same result. connecting it back to Za and Zb also doesn't work anymore and gives the same result.

If I've read that correctly, it's the motor or the wiring between the Duet board and the motor. Possibly a bad crimp?

i dont think it is the motor as they do work on other drivers, i didn't touch any cables but i will check the cables and see if they are alright.
edit: i think you're onto somthing, i now used the x axis wiring on E1 and this works flawlessly.
placing both Z axis motors on Za and Zb again now works and moves the z axis but is just very noisy, getting closer

i went ahead and replaced the cables today and that resolved the issue. i don't know how the cables went bad but either way its fixed.
Thanks a lot to you and others for the suggestions.jeff

@Twigz Pleased for you that the issue is resolved.
