Extrusion motor error: "short to ground reported by driver(s) 3"
-
I'm upgrading my CR10 S5 to a Duet Maestro (I had another forum topic on that, felt like this was a different topic though) and I had everything just working for about 10 minutes and then the extrusion motor stopped working. I now get "Error: short to ground reported by driver(s) 3" whenever I try to use it.
The thing is, I actually upgraded to the Maestro because the extrusion motor stopped working on the original board. Through research I thought it was the motor driver, but now I'm obviously second guessing that conclusion... The extrusion motor seemed a bit slow but it definitely worked when I first wired up the Maestro.
I've tested 2 different motors and changed out the wiring, I haven't had any luck. I also tested the motors with an Arduino and an A4988 driver and they still work. I really hope my new board isn't messed up somehow now, everything else seems to work just fine still.
Any help would be greatly appreciated!

I think it might be the wiring after all. Came back to it later and the error disappeared and the motor acted differently. I then put in some test wires and it worked! I've heard stepper drivers can act differently when they heat up so maybe that was why I got the error before on good wires? I'll try a print with it soon and see if it holds up.

Please let us know if it stops working again.

if it was a wiring issue you really want to find a proper solution to that, next time the driver may not survive.

@Phaedrux Sorry it took me so long. I bought a new motor to make sure.
@bearer Oh, good to know... I probably let it throw that error about 30 times...
After several attempts at soldering together a cable and buying a new motor (it was just the cable), I finally got it working through a whole print, although now I'm dealing with a new issue in these weird lines...

^ Forgot to post the image, haha.

Could be layer shifts. Could be filament tension.

@Phaedrux You're the best! I tightened up the filament tension and lowered the acceleration a bit. I printed another and only minor ghosting now!
Seriously, your help on both of my threads has saved me immense headaches.
