Help PID tuning Dyzend Pro



  • 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

    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.

    Paramètre D changer et le résultat est le même

  • 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



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



  • @FBG comment changer cela

    Does it work, or does it not work?



  • now does it not work



  • Auto tune cancelled because starting temperature is not stable

    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.



  • @Phaedrux OK i try



  • 12/10/2020 à 22:41:21 Auto tune phase 1, heater on

  • 12/10/2020 à 22:48:39 Auto tune heater 1 completed in 443 sec
    Use M307 H1 to see the result, or M500 to save the result in config-override.g
    12/10/2020 à 22:44:26 Auto tune phase 3, peak temperature was 229.7
    12/10/2020 à 22:44:03 Auto tune phase 2, heater off



  • Now i execut the command M500 and M501



  • Toujours des fluctuation de temp

    Ok if that successfully worked you can do as DC42 said above and edit the resulting M307 command in config-overide to increase the D value.

    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.
