Heat Brake Fan Not Running



  • Hi Everyone,

    I just got my Ender 3 Pro assembled with the CR touch and also upgraded to the silent 32bit mobo. I started a test print of a 25mm cube and noticed that the fan for the heat brake (not the layer cooling fan) is not running. I'm a little worried that there might be a problem with the printer or the fan. Is there a temperature that this fan comes on at? I know with my Purse the heat brake fan comes on where the nozzle temp gets to 50°C. I didn't seen anywhere in the menu to turn this fan on only the layer cooling fan. I'm currently running Marlin version 1.3.1 . Anyone run into this issue or know a fix for this?
