Compile error USE_CONTROLLER_FAN

Compile Error

When I compile with USE_CONTROLLER_FAN I get an error:

which board are you using and where have you wired your controller fan to?

[android444]

Default configuration file 'configuration.h' Changes only in 'configuration_adv.h'

[oakdesign]

Default for which board? If for RAMPS in EFB Mode Extruder Fan Bed Setup the FAN_PIN1 is set to -1 so you need the Signal pin number you have wired your Controller fan to

This is badly done. Pin should be selected in xxx_pins.h

sorry to jump in but im having same kind of problems it seems to me that the FAN_Pin sections is not well documented and share same name on multiple sections for what i see the USE_CONTROLLER_FAN is for the fan turn on automatically whenever any stepper is enabled

the part from exruder fans i never got to work out this section

#define E0_AUTO_FAN_PIN -1
#define EXTRUDER_AUTO_FAN_TEMPERATURE 50
#define EXTRUDER_AUTO_FAN_SPEED   255  // == full speed

my extruder is set on the E0 slot and im using ramps motherboard EFB, when i try set a pin #define E0_AUTO_FAN_PIN 9 always get error, by default it should work sense fan is conected on D9 of ramps maybe im missing something no idea, but i never got my fan to start working when goes above AUTO_FAN_TEMPERATURE 50, only got to work by using the comand M106 S50 its a litle confusing, dont get it why doesnt work sense is already set on pin.h

#if ENABLED(IS_RAMPS_EFB)                      // Hotend, Fan, Bed
  #define FAN_PIN        RAMPS_D9_PIN
  #define HEATER_BED_PIN RAMPS_D8_PIN

In Marlin we have 3 kinds of fans

• Part cooling fan. For most the most useful one. Needs to be PWMd to be adjustable. The one mend in 'EFB'.
• Extruder fan. To cool the cold end of an hotend. Makes most sense when a hotend is hot. Could be permanently connected to 12V if ware and noise is no problem.
• Controller fan. Fan for cooling the mainboard - especially the stepper drives. If the steppers are not enabled they probably do not need cooling. Could be permanently on, ...

Ok this my working setup for E0_AUTO_FAN_PIN and USE_CONTROLLER_FAN I have both fans wired through a IRF520 Mini Mosfet. From every IRF520 I have a single Signal wire to one of the Signal Pins on the Servo Pins D4 D5 D6 on the RAMPS so for

define E0_AUTO_FAN_PIN 4

define CONTROLLER_FAN_PIN 5

and D6 I'm using for LED case light

define CASE_LIGHT_PIN 6

setup in the configuration_adv.h On the RAMPS Pins D2-D11 and D44-46 are PWM cabable
