@Phaedrux :
I solved my problem, I add the command M501 at the end of my config.g.
I use in my Duet2WiFi the firmware version 3, RepRapFirmware Configuration Tool v2.1.8.
I made the autotune in the BED and I add the Heater model parameters at the config-override.g.
Now it's working well, thanks for the support.
