  This might be thermistor losing contact with the block or wires losing contact. It can also be the heater wires losing contact somewhere. To diagnose, you can try and wiggle the wires when you preheat the hotend and watch the temps. Then you will know what needs replacing. I once had a thermistor that was faulty, I replaced it, the problem went away.

  You can try running a PID tune on the nozzle and see if that helps.

    Unfortunately, the temperature variation still is above 3° C.

    Ok, I never heard of that and read into it. As this is there easiest thing to do, I’ll do this ASAP and see of it works.

  Replace the resistor and temp sensor. I would also replace the hot end itself, at least for my printer it was like 10e

    Weeeeeeell the last time when I tried to replace the hot end, I screwed up so hard the printer was not usable any more after that 😂

      How…? Mine is literally 2 bolts and the bowden tube retaining bolt? Plus of course the sensor and resistor cartridge. I have no experience of direct feed hot ends tho.

        Guess I have been repeatedly too stupid to buy parts up to speeds and then trying to solder them together, which failed. By that, I destroyed the original equipment and got no working replacement in place.
