Hemera goes wild! heat and no moving...

@mitch
switching 3+4 pin was not helpful..

Also interesting is, that the sound doen´t stop anymore. I must turn off the machine. otherwise the sound of hemera doesn´t stop

Thanks

I´m workig with this plugs since months and it works with the E3D slimlime motor. So I think the plug is ok...

@barbarossa-cologne have you tested the phases yet?! Blindly changing the pins isn’t going to work, and may damage the Duet and/or the motor. Disconnect the motor cable from the Duet and check!

@droftarts
Couldn´t test it because I don´t have a multimeter.
I don´t understand that I can´t read how to wire the motor exactly. Only @mitch had the information about switching the 3+4 pin...
E3D needs the same good support like Duet does it...

And at this moment, I don´t know if the motor is already not working anymore.

how did you measure the resistance that you said you did?

@Veti
A friend came to my house with a multimeter.

page 6 has the motor wiring.

but if your say that each phase had the correct resistance then the motor is fine and not broken.

@Veti
Ok your rigth. I changed the wiring like @mitch and page 6 says, but it´s still not working.

Veti

are the colours of the wire matching on the duet side?

If you don't have a multimeter you can use this method to match the phases:

With the motor wires not connected to anything, spin the spindle between your fingers. Short two of the wires together, then spin the spindle again. If it is much harder to spin than before, those two wires belong to the same phase. Otherwise, try again with a different pair of wires shorted together.

Problem solved. Motor wasn´t working after wrong wiring.
Thanks to all!!
