/** * Assign more PWM fans for part cooling, synchronized with Fan 0 */ //#define REDUNDANT_PART_COOLING_FAN 1 // Index of the first fan to synchronize with Fan 0 #ifdef REDUNDANT_PART_COOLING_FAN //#define NUM_REDUNDANT_FANS 1 // Number of sequential fans to synchronize with Fan 0 #endif
enable this
and add something like
#define FAN1_PIN pin number...
I cannot remember what pin the fan expander uses but its either 11,6,5 or 4
