I have a new (less than a month old) Ender 6. The part cooling fan never stops running. This is not the fan for the heat break/heat sink, but the fan that blows on the printed material at the nozzle. I have tried turning it off from the display menu, and also by Gcode commands, but it never stops. Sitting idle waiting for work - 100%. Printing - 100%. After printing complete - 100%. It never stops or slows down regardless of the gcode commands or screen inputs.
I have firmware version 188.8.131.52 with BLTouch (the BLTouch is the only upgrade performed so far).
Any ideas? Is this a mainboard issue? I have verified the fan is plugged into the correct port on the spray board.
