I want to add a Fan.
Generally I have problems to understand the link between the fields inside the configurator of Repetier und the Ramps 1.4 board.
1.In Repetier Configurator
Fan Pin: "Heater 2 normally used for extruder 1" -- is this D9 on Ramps1.4?
2. For Z-Probe I have to define a pin in repetier firmware.
Is the "Digital Pin 1" in the configurator the D1 in the AUX-1 block on board?
Or what pin on the Ramps1.4 do you use for Z-Probe?
Any help is welcome .. Thanks!
