Axis stop working....



  • Hi,

    the X-axis motor has stopped working ...

    the first thing I thought was that the engine had broken down, and I changed the connection of the X axis to the Y axis ... and, the engine works ....

    It seems a problem of the board, the motors that connect to the socket Z of Duet does not work.

    in the print that I made yesterday it worked ... and I have not changed anything, neither of software nor of hardware.

    What I can do? How can I verify that it is not fault of the Duet board?

    Thank you

    What does the M122 report show as the status of that driver, after you have commanded it to move?

    I cant see nothing about this driver.... how i have to do? i have to home and after M122?

    @peirof said in Axis stop working....:

    Driver 0: standstill, SG min/max not available

    That indicates that you have not moved any axes since you powered up the Duet or you last ran M122, whichever is later. My request was:

    What does the M122 report show as the status of that driver, after you have commanded it to move?

    i haved manual move the axis near end stops, and X axis NOT move up, to endstps, but moves down and after down... seems how only moves down... maybe axis endstops its triggered??

    and... second test... after homing, i have comisioned Duet Z move... and this motors works.... but only to a limit....

  • i have the same issue. and it doesn't show any movement but i hit homing. z axis just buzzed a very long time. i wanted to hit reset but new i would lose data so i let it go. i did try turn off motors during and nothing stopped it. feeling so frustrated and alone!

  • z axes just humming like not enough current.
    this was working perfect for weeks.
    i just dont understand.



  • have you tried to connect the stepper not working to another axis?


  • administrators

    @mikeb said in Axis stop working....:

    z axes just humming like not enough current.
    this was working perfect for weeks.
    i just dont understand.

    The most likely reason is a bad crimp connection in that motor cable. A failed driver chip is another possibility.



  • i will ohm out the wires and try to use different axis driver. thank you for response! thank you



  • ok i hooked up two spare motors and what happened was both are buzzing but one turned as normal and other was back and forth couple of steps. think check crimps one one not turning as normal.



  • As a side note to this issue, and any other issue that might be related!

    I had a project in which we used huge amounts of connectors pretty much identical to the ones used on the Duet boards. It was not the first project, as I had very good previous experience with the same type of connectors. Some if the guys crimping the pins on the wires misplaced them in the crimping tool and they have squeezed the contact area way to much. We had to get the pins out of the plastic bodies and re-spring them for quite a few of the cables. The problems were random, so finding the actual cause was anything but simple!

    Also, we saw that even "compatible", these connectors are not 100% identical between manufacturers, with slight variations in the latching dents and the actual pin shape. If all sourced from the same manufacturer, everything is OK. But this is a relatively low cost connector, though a pretty well designed one, so there are a lot of manufacturers and only few suppliers guarantee the manufacturer (go for big suppliers like Farnell, Mouser, DigiKey, TME in order to have guaranteed supplier, but avoid generic ones - like Multicomp for Farnell). I think on Duet the connectors are from Wurth!



  • im still using supplied ones from e3d.



  • update...i updated my firmware and that fixed my motor issue on z axes.
    but now i have no controle of my eo heater and the bed thermister is what both eo and bed are displaying. crazy



  • @mikeb ALL FIXED NOW. i fixed numbering of heaters and thermisters. the configurator had it all messed up. never did that before. was same config as before. guess update changed something. THANKS FOR ALL HELP EVERYONE.



  • ok now z motors stuttering again. started in middle of a print! i just cant win



  • @mikeb i figured out one of the motors has let the carriage get in a bind(one side 3/4 turn off). ?


 

Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
