    Sorry for cross-posting it in here, but the troubleshooting forum is dead, and I'm seeing people get a lot better results in here.

    I'm trying to run a Hemera 24v kit on my Ender 3 Pro that has been changed to SKR Mini E3 v1.2 board.

    The machine boots up, and the idle tool temp is bouncing between 94 and 122 degrees C. Any attempt to change the temperature of the tool, or initiate PID Tuning, brings up the error and squeals the alarm for Heating Failed E1.

    I've tested the heating cartridge resistance with a multimeter and it shows at 20 ohms.

    What should I be checking here? I haven't been able to print since March, and am ready to give up if I don't get this going soon.

    The failure possibly means that your temperature probe is failing (maybe you tightened it too much, and broke it?). Make sure everything is wired and connected properly too.
