    Good morning,I bought the complete kit taurino, ramps and lcd control.I have a machine with one extruder and wanted to mount a fan cooled extruder.I installed the firmware marlin V1 with the settings for my car.I made some tests and I realized that the PLA machine pre-heating heats but also turns the cooling fan on the D9 pin. then I pressed the next entry "cooldown". the extruder cools but the warm bed and contiunano fan to work.is this normal?I tried to adjust the number of revolutions of this fan in fan speed but nothing to make the fan runs always equal.
    Help me.
