    Hi,

    I got the hemera last year but because of time and problems unrelated to the hemera I never got it working. The problem I had at that point is now fixed, but now my motor doenst turn when doing so from the menu. It just shakes and it seems to block

    The nozzle is up to temp (200 c)
    Esteps are set to 409
    Ive tried various cable configurations
    Mah is set to 0,94 mah in settings and saved to eeprom

    Really don't know what to do now

    I went through this. You probably have it wired wrong... try using your factory wiring and see if the motor turns (you don't even need to have it all hooked up).

    Hey guys, was there any update to this? I've been having the same issue. Wiring seems to be correct, unless the part that goes into the board needs to be re-pinned.

    Updating the driver current seems to have made it "attempt" to turn more, which leads me to believe that the wiring is correct.

    For myself, I've only got the stepper motor connected to the Hemera, no heater block / heat break - as originally I thought something was stuck inside the extruder.
    I've also taken off the heatsink to check the inside, and nothing seems stuck - I'm able to spin the gear on the back with my thumb with a little pressue.

    So! Turns out that the I had to re-pin two of the wires in the connector that goes into the board.

    Asked around on the Discord and here's a little diagram someone sent over:

    For me, I had to swap over the blue and red wires.

    Hope this helps!

    Unfortunately I have the same issue, tried the combo in the diagram as well as the swap you suggested, but it does nothing just click click and that's it then doesn't react anymore. Got an Ender 5 too. Anyone else have bright ideas?
