M307 H1
Heater 1 model: gain 545.5, time constant 191.5, dead time 18.0, max PWM 1.00, calibration voltage 24.1, mode PID
Computed PID parameters for setpoint change: P3.5, I0.059, D43.9
Computed PID parameters for load change: P3.5, I0.094, D43.9 -
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.

Thermistance 500 ° C Thermorétractable noir
#Modification du fichier config.g
Recherchez les paramètres suivants et remplacez les valeurs: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

Auto tuning heater 1 using target temperature 220.0°C and PWM 0.50 - do not leave printer unattended -

-
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.

Ok je vais essayer sa
-
temp. régler a 220 for test
elle monte a 232 avant de descendre vraiment doucement jusqu'à 220 -

temp. set to 220 for test
it goes up to 232 before going down really slowly to 220If it overshoots the target, increase the A parameter. Try increasing/decreasing it by 5% or 10%.
