I have a prusa einsy rambo running marlin bugfix and i have discovered that the fan 1 pin is shorted to the bed thermistor circuit. when the fan is turned on it triggers a bed mintemp error. so i switched fan 1 and fan 2 pins in the firmware and am trying to just use the second fan pin for my main part fan. the problem is, it doesn't work. i get no power out of fan 2 pin. but it doesn't trigger the mintemp anymore. could the other fan pin be compromised too?
