Duet 3 6HC motor issues



  • Only 1 of my 6 stepper motors on my duet 3 6HC are working any more.
    No issues being reported in M122.
    I have tried rolling back to 3.1.1 and back to the latest 3.2 beta 4.1 without avail.
    I have removed the board from the machine and inspected it but I can't see any areas where the magic smoke has escaped.
    I have also checked the fuses and they are both intact. If it was damaged, I would expect none of the drivers to work?
    Anyone have any thoughts?

    What does M122 actually report for the drivers, both before and after commanding movement?



  • @Phaedrux I'll reconnect and post a report.
    It's only driver 0 that actually moves.
    The thermocouple for the heated bed also reads the incorrect value.

    That was after a command to unlock my tool lock (driver 2) and home the machine in X and Y (driver 0 and 1).
    Only driver 0 moved.
    This is after a command to move the bed (drivers 3 to 5)

    If I try and heat up the bed, the temperature goes down...

    edit: the reset in the last M122 was me hitting emergency stop so the motor that was actually moving wouldn't cause the carriage to come into contact with the frame



  • I've unplugged all the drivers and have connected only 1 to driver 1 and there in no movement. It appears as though only driver 0 is working any more


  • administrators

    1. Send M906 and M913 without parameters, to check that the drivers have been configured with the correct current. Also send M92 to check that a sensible steps/mm has been configured.
    2. When you try to move motors, do the motors become difficult to turn by hand, and do they become easier to turn again when you send M18 to disable the drivers? That would indicate that the motors are being energised by the drivers.


  • @dc42 here is the output of M906 and M913

    m906
    Motor current (mA) - X:1400, Y:1400, Z:2200, U:1400, E:800:1050:800, idle factor 30%
    
    m913
    Motor current % of normal - X:100, Y:100, Z:100, U:100, E:100:100:100
    

    When commanding the z motors to move, they are still free to move, indicating they are not being energised.
    For completeness, here is my config.g

    I forgot to say: also send M584 without parameters, to check that the drive mappings are as expected; and send M569 P0, M569 P1, M569 P2 etc. to check that the drivers have not been disabled.

    I think something is wrong with your configuration, because the reported driver position is not changing when you move Z.

    To test five drivers at once, I normally send the following commands:

    M584 X0:1:2:3:4
    M906 X1000
    M913 X100
    G91
    G1 H2 X10

    and see which motors move.



  • @dc42 M584 driver mappings

    m584
    Driver assignments: X0.0 Y0.1 Z0.3:0.4:0.5 U0.2 E1.0:1.1:1.2, 3 axes visible
    

    I modified my config to replace the M584 with the following line

    M584 X0.0:0.1:0.2:0.3:0.4:0.5 Y1.0 Z1.1 E1.2
    

    Here is the output from M584 with the modified driver assignment

  • I've ran a cut down config with no change.
    When turning the heated bed on (SSR controlled 240v), the temperature decreases from 22 degrees c to 11 degrees c before faulting

    You need to swap the 2 wires from the thermocouple where they connect to the daughter board.



  • that'll be after i disconnected everything and reconnected it all one by one to make sure there were no connection errors.
    I am still unable to use drivers 1 to 5 on the 6HC.
    I have generated a new config from the config tool without change



  • Same config on another duet 3 works, so I don't think its a configuration issue.
    @dc42 any other thoughts?



  • @dc42 any more thoughts on this?
    I still can't use drivers 1 to 5 which means this board is a very expensive but useless paperweight


  • Moderator

    Sorry for the delay. We'd like that board back for testing. So please contact your vendor and initiate a warranty exchange. Include a link to this thread as authorization.


  • Moderator

    @jay_s_uk When you send it back can you include a note to "test with ATE and send to David for examination"?



  • @Phaedrux will do!
