Maestro Error: Short to Ground Driver 3



  • My Maestro after 2 hours gives a short to ground driver 3 error on my extruder. I have check my extruder wire with a multi tester and everything is in order. I have also switch the wires from my x axis with my extruder wires yet the error persist.

    Then I started reading the forums a person suggested to pull the plug on the board while the error is happening and I press extrude and retract but the error is still there

    Any suggestions?

    How do I relocate E0 to E1



  • If it is new, was wired correctly and the driver failed I'd see if the Duet3D admins would authorize a warranty replacement and return it to the vendor.

    To map E0 to E1 I think you just need to change M569 P3 to M569 P4 and M584 E3 to M584 E4 in config.g (the original lines will have other parameters as well, keep those unchanged)



  • My board almost 2 months with me ever since I got it had short to ground error on driver 3 intermittent error. This forum is really great help. I even bought the crisper to attach the Duet connectors because I read it here in the forum that it is usually a loose connection. After I switched all my connectors the error seldom happens but after some long prints it happens and I read somewhere that it might be the hotend clogging so I replaced it with an original e3d v6 with a titanium heatbreak but the error still happens but more seldom but after a few days of printing it comes back so I upgraded my extruder from a titan to a bmg still has the same problem.

    I tried what you suggested the tool disappears on the menu....BCEB7F3E-62F6-475F-BC03-58C6C0E320B0.png



  • post your original config and someone will probably sort you out here

    hmm, should have worked I just tried generating two configs with RepRapFirmware Configuration Tool. One for E0 and one for E1, the only thing that changed were those two lines.

    Your right tried it again.....so how do I inform the admin about my board

    Just had to change H1 to H2 for the temp sensor to work and now I even have my Extrusion Control working....

  • @vits88 said in Maestro Error: Short to Ground Driver 3:

    Just had to change H1 to H2 for the temp sensor to work and now I even have my Extrusion Control working....

    ah, you could have left the heater on E0, didn't occur to me to specify that.

    so how do I inform the admin about my board

    they generally get to it pretty soon, but it varies, could be 5 minutes, could be more, rarely more than a day.



  • @bearer
    Thank you for your help so does that mean I could have used heater 1 and temp sensor 1 and also fan 1 and just moved the extruder connection to E1 and it would have worked....
    I thought it had to be paired ....


  • Moderator

    Just to confirm you troubleshooting thus far, you had a short to ground error on the E0 driver and after changing to E1 driver the error no longer occurs?

    Board is 2 months old? Where was it purchased?



  • @Phaedrux
    No I have a zero to ground error on driver 3 it was intermittent when I start printing it runs ok but after an hour or so the board would give me zero to ground error on driver 3. After reading the forum check the wiring which I did with my multi tester no problems with the wire. The error still occurred then I changed the connectors to that was included with the duet, I thought it becomes loose while printing and still the error occurred. I even switch the wiring used the x wiring with the extruder wire still it gave me the same error. I thought maybe the extruder motor is having a hard time pushing the filament so from a titan extruder I upgraded to a BMG extruder still the error occurs. Finally I read in the forum when the error occurs to pause the print and to pull the extruder wire from the board and see if the error would occur and it does, this meant the the error is from the board. He then described what he did was to relocate the extruder from E0 to E1 which I did and started an 11 hour print which is still running now on 9th hour And still running....

    I bought my board from Filastruder they are great, fast delivery even when it was during the lock down.


  • Moderator

    @vits88 If your board was purchased within the past 6 months we approve a warranty replacement. Please contact Filastruder to initiate a warranty replacement. You can point them to this thread as authorization. Thank you for your patience and sorry for the inconvenience.



  • @Phaedrux
    Great thank you and will do....
