Fan on D9 setup help

cinpro

the fan on D9 E0 won't turn on.I did the setting on Repetier Firmware, uploaded with Arduino IDE after sending M502 and M500 to the board. something still isn't right. the fan does work, I switched it with the extruder cooling fan and it fired right up. I also checked that there are no breaks in the wires, and that there is no voltage at D9 when switched on. I copied the following out of AI so someone can look. hope I got all the file you might need. as far as I can tell it is set to board 33. Ramps 1.4 with Arduino Mega 2560 R3

Repetier

Have you enabled that feature?

/** Should support for fan control be compiled in. If you enable this make sure

the FAN pin is not the same as for your second extruder. RAMPS e.g. has FAN_PIN in 9 which

is also used for the heater if you have 2 extruders connected. */

#define FEATURE_FAN_CONTROL 1

Also make sure not to use HEATER_2_PIN for something as it is identical with fan pin.

I have the same problem no signal on D09 can you please help me?

Repetier

See answer above your post. Set fan pin to 9, enable fan feature, do not use HEATER_2_PIN for anything and also FAN_PIN not for anything else like extruder cooling fan.
