Problems with steppermotor



  • Hello i have a Problem with my Motors. I`m currently updating my anet E12 to a duet Wifi with Firmware3.

    All cables are connectet but when i press home z for example, the motor will turn a little bit in both direction and make horrible shatter noises.

    i dont now what kind of problem it is, maybe someone can help me.

  • Also with one Firmware i was able to move one motor but since i change something nothing will work anymore



  • please post your config.g and your homing files

  • duble check your wires, did you get some error messages in the console if you try to home your printer ?


  • administrators

    Most likely you don't have the stepper motor wires correctly phased (CAUTION: this can damage the drivers!), or there is a bad connection in one wire.



  • I think all wires a correct connectet. in other orientations the stepper does nothing at all. And then i get a error message, but not when the stepper stutters

    is there a way to check if the drivers a damaged?



  • @MauriceM said in Problems with steppermotor:

    M584 X0 Y1 Z2 E3 ; set drive mapping

    you can swap the drivers change the wiring lets say swap x and y and add M584 X1 Y0 Z2 E3 ; set drive mapping and try again.



  • So i achieved that all motors turn except the z motors

    It was a cable Problem, i hope i didnt demaged the z drivers



  • Thanks Guys, now it works , i bought cables with different colour matching. Was a stupid mistake but i damaged nothing and now i can enjoy my silent printer.


  • administrators

    @MauriceM, I'm glad it all worked out for you and didn't cause any damage. Unfortunately, for stepper motors that have 6-pin JST connectors on them, there are at least 2 different pinouts used. So you can't rely on the wire colours being correct, especially if the motors and cables were purchased for different suppliers.

    Can you tell us what VIN voltage you used, and what type of motors? Did you get any "short to ground" warnings from the firmware? I'd like to get a better idea of when the internal short circuit protection in the drivers works.



  • VIN in 12.5V and the type of Motor is: 42SHDC3025-24B.

    But i never had a short to ground issue.
