What should the auto fan settings look like? From the screen, the fan turns on.
You can change #define E0_AUTO_FAN_PIN -1 To #define E0_AUTO_FAN_PIN FAN_PIN Or #define E0_AUTO_FAN_PIN FAN1_PIN Or #define E0_AUTO_FAN_PIN FAN2_PIN This depends on which fan do you want to set.
then compilation error, You cannot set E0 AUTO-FAN PIN equal to FAN_PIN
My mistake , try to set it to FAN1_PIN or FAN2_PIN, because normally FAN0 is for cooling printing model.
Thanks, earned only after I wrote E0_AUTO_FAN_PIN PB1
