1. The europian warranty is 2 years.
2. the wiring and extrudermotor have been replaced.
3. so the story about shafing and bending is not in place.
4. The same error (and thats coming from the duet) when switching the extruder motor happend.
5. the motor stering from extruder one is connected to extruder 2 from the duet. causes motor 2 to fail so saying that it is the motor or motor wiring is false.
6. If you sell in europe you have to follow the europian rules.

I like to here from you.

The problem did follow the extruder motor. The reported error was the same.
about wiring: it was working perfect for a long period. So the wiring cannot be the problem.

@phaedrux
The extruder motor has a connector and has been delivered with ready wiring with connectors installed.
making a mistake is not possible.
and indead always the same error: short to ground error for driver 3

@phaedrux

I switched the wiring from extruder 1 (the problem) to extruder 2 and the wiring from extruder 2 to extreuder one.
By testing both extruders extruder one workt perfect again.
extruder 2 had the problem now.
The error message was the same.
so the problem followed the extrudermotor.
error message: short-to-ground reported by driver(s) 3

@swanny

wiring switched. behavior and error the same one the other working extruder.
So changing the wiring replaces the error to the other extruder but the same error message still occurs.

@phaedrux
going to try that this weekend.

Re: Driver 3: short-to-ground

To avaid a lot of confusing I placed a new extruder motor en replaced the wiring.

It has the same result:

The extrudermotor gives an error after about 30/60 seconds.
if it takes a little bit longer now a fase B error is also displayed.
Warning: motor phase B may be disconnected reported by driver(s) 3
The extruder motor switches in about 2-4 times a second from CC to CCC.
My other 3 extruders on the toolchanger act normally

What is the solution?
