Bonjour apprès plusieurs essai d'impression j'ai toujours se message d'erreur Cancelled printing file 0:/gcodes/CalibrationCube.gcode, print time was 0h 9m Error: Shutting down due to un-cleared heater fault after 600 seconds

Ma température fluctue beaucoup de 5°C régler a 220 en impression elle monte jusqu'à 225
et baisse a 218

PID a bien etait effectuer

Help Please

dc42

If you haven't already run heater tuning on your hot end, do it.

If you have already run heater tuning and copied the resulting values into your M307 H1 command in config.g, increase the D parameter in that command until the temperature is stable when the print head is not moving. Try increasing it by 30% initially.

nobody for helping please

Is auto tuning successful? Are you starting from room temperature?

How did you save the resulting values? Sending M500 saves them to config-override.g and M501 at the end of config.g loads them.

The problem is the heater, not use 50w. Use 40w or 30w

chris974M

Oui auto tuning ok apres autotun. M500 il enregistre bien dans config-override.g

chris974M

@FBG comment changer cela

Does it work, or does it not work?

chris974M

now does it not work

Auto tune cancelled because starting temperature is not stable

Phaedrux

I suspect that's because the high temp thermistor is less accurate at low temps. You could try preheating it a bit before starting the tuning process.

chris974M

@Phaedrux OK i try
