Hey I want to upgrade my A5 with the TMC2208 Stepper Drivers. So i need a additional fan for the drivers. I bought a 24V 40x40x20mm fan, but where an how i can connect the fan on the board?
Comments
* Controller Fan
* To cool down the stepper drivers and MOSFETs.
*
* The fan will turn on automatically whenever any stepper is enabled
* and turn off after a set period after all steppers are turned off.

#define USE_CONTROLLER_FAN
#if ENABLED(USE_CONTROLLER_FAN)
#define CONTROLLER_FAN_PIN P1_28 // Set a custom pin for the controller fan
#define CONTROLLERFAN_SECS 60 // Duration in seconds for the fan to run after all motors are disabled
#define CONTROLLERFAN_SPEED 140 // 255 == full speed
//#define CONTROLLERFAN_SPEED_Z_ONLY 127 // Reduce noise on machines that keep Z enabled
#endif
