Hi Srek,
Thank you for your response.
I have tried a lot of things, such as choose the configuration
#define DEFAULT_bedKp 97.1
#define DEFAULT_bedKi 1.41
#define DEFAULT_bedKd 1675.16
in place of
//#define DEFAULT_bedKp 10.00
//#define DEFAULT_bedKi .023
//#define DEFAULT_bedKd 305.4
But unfortunately, I know nothing about the PID progamming and so, I don't know what my changes can do.
Nevertheless, I have observed that now, the heating process can work until reaching the temperature 60°C.
But after, if the gap beteewn the consigne and the real temperature is greater than 5°C, the printer fails with an error message "Heating error".
With a temprerature arround 75°C, It has also happened that the printer stops during the print with that message "heating runaway" (emballement de chauffage, in French).
Could you please tell me how I can change the PID to improve my experience ?
Thank you,
Jacques
