    I finally figured my previous problem with the Hemera, replaced the thermistor, and this time get it and the Hemera fan plugged into the right sockets, as their wiring type is opposite way from the standard Ender 3 setup.

    So now that I have everything wired up, fired up, PID Tuning done, crank up the tool temp, looks good and stable, no probs, then tell it to print the bed levelling test.

    Unit warms up the bed, then the tool, then starts the head and bed around, and then the wailing alarm strikes: Thermal Runaway E1.

    I have attached a screenshot of my thermals graph to see if anything jumps out to you guys.

    Anybody have any ideas what I should be checking here?
