Extruder Fan not turning off



  • Not sure if this is a bug in the firmware or mine doesn't work right. My other 3d printer (non creality) will turn off the extruder fan when the nozzle temp is cooled down. I know there are 2 fans, one that cools the printed part while it is print. It's not that one I am talking about. I am talking about the one above the nozzle blowing on the heatsink that never seems to turn off at all and it's loud. The fan runs when I just first turn the printer on and at 29C and never stop.
