CNC Fans PWM not working correctly? Always on, no control or turning off possible. #44
I have this problem on all three (six?) CNC controller fan ports. I attached a few different 24V fans but the behavior didnt change.
I dont know if there is an issue with the board or if I made a mistake inside the marlin configuartion.
I tried SOFT_PWM on and off, on different fans that I knew worked with both modes on the stock board.
