    It could be a loose wire, or a one that is about to snap off. If the cable is bad or on the way out, it could easily be screwing with the resistance measurement. I wouldn’t think that just a loose thermistor could cause that mess of a graph, but who knows.

    It’s the motion bit that you mentioned that gave us just a little more data.

    If you can isolate the wire for the thermistor, jiggle it around at different points to see if you can replicate the rapid temperature changes.

      Hmm, I might have to order a new replacement and see if that helps then. I had replaced the hot end assembly with the spare that came with the printer a couple weeks ago. I was very careful with the change, but I suppose it’s possible I damaged a wire in the process. It’s been running smoothly since then though, until today when the temperature started swinging wildly.

        Yeah, something got loose or broken. Try your best to isolate the fault while you wait for a replacement though. It’s always good to know absolutely sure what happened to hopefully prevent the issue again in the future.
