Hi
My 3D printer is a Prusa i3 Hephestos without a heated bed.
This means that it has an unused D8 output. Now I want to connect the extruder/electronics fans to D8.
I already tried to change "fan pin for board cooling" to heater1 or digital pin 8 in the repetier configuration tool but that didn't work.
Do you know what else I could try?
Edit: the fans are running when using the blink sketch for pin 8. So it doesn't seem to be an electric issue
