        I'm not sure what else to say. This is a very difficult thermistor/heater combo to auto tube. 50W and 500c. I think your best chance will be to preheat as little as possible so that you can get an auto tune complete and then manually adjust the PID values to try and get it stable at temp.

        How does it perform with the values provided by Dyze without auto tuning?

            You can try using M570 H1 P60 T25 S120 to change the sensitivity of heater fault detection to allow time for it to stabilize.

                Si nécessaire, vous pouvez effectuer des ajustements manuels des paramètres du modèle M307, comme suit:

                Si pendant le chauffage initial, la température dépasse la cible, réduisez le paramètre A. S'il dépasse la cible, augmentez le paramètre A. Essayez de l'augmenter / le réduire de 5% ou 10%.

                cela doit etre fait dans config-override.g

                  @chris974M It must be done to the M307 command that is being sent last. So if you have an M307 H1 in config-override.g then you should change that one, but as I said before, cut and paste it into config.g and remove it from config-override.

                        Did you add the M570 command I posted?

                                Ok, so you may be able to adjust the PID values now to get it a bit more stable. Try increasing the D value a bit.

                                      What values are you using? and how are you changing them?

                                      That heater is really intended for high temps, if you're only going to be printing in the 200c range why not just change out for a better matched heater. Dyze has a 300c version that should be much easier to tune.

                                      Have you tried tuning this heater to a hotter temperature like 350 or more?
