Duet3D Y-Axis Motor turning in only one direction
-
Hello,
I am upgrading my Geeetech Rostock 301 and have installed a Duet3D V1.03 board. The Z and X Axis motors work correctly, however the Y-axis motor is acting strangely.
Sometimes it will turn both clockwise and anti-clockwise when I send a G1 S1 Y50 command, but only for about a revolution before it reverses.
Once this happens, it will only turn in one direction, if I send a positive or negative ammount.
If I change the motor configuration, then the motor will reverse it's direction, once again it will only turn one way no matter what command it is sent.
I have checked multiple cables, motors, and board connections - it only happens on the Y-axis.
So far, it has never worked correctly.
I am running the latest firmware:
"RepRapFirmware for Duet 2 WiFi/Ethernet version 2.03RC4 running on Duet WiFi 1.02 or later"
Do I have a faulty board, or am I missing a setting or configuration?

change the drive mapping using https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping
and assign the y axis to the e1 motor.
if it works then, there is something wrong with the y stepper. -
Hello,
I tried your suggestion, the motor vibrates and I receive an error message:
"Error: short-to-ground reported by driver(s) 3"
I have identified the pairs of cables, and have tried reversing them in the connector, and it is the same result each time.
I also switched back to using the Y-axis, and the motor will only turn one way.

driver 3 is E0 extruder. that would be another problem
if it vibrates that would indicate a wiring problem.
verify that you have the correct phases on that motor with a multimeter. -
My apologies. I connected the motor to E1, and it works correctly with the wiring as I originally connected it.
It seems I have a faulty board.
Any suggestions?

It does sound that your Y motor driver is faulty, and you should ask your supplier to replace the Duet. Assuming it's a genuine Duet, see https://www.duet3d.com/warranty.
