Here is the firmware I used.

I am still searching, but my marlin and arduino knowledge is limited, but I’m learning! 😉

The motherboard used is 33

I found the M106 in marlin_main.ccp and seems ok to me, but I can’t finf in the other files where the fanSpeed variable is applied

#if defined(FAN_PIN) && FAN_PIN > -1
      case 106: //M106 Fan On
        if (code_seen('S')){
           fanSpeed=constrain(code_value(),0,255);
        }
        else {
          fanSpeed=255;
        }
