Question: FANs Configuration SKR v2 #33

Open emiliorizzo opened 3 years ago

I've just received a BIQU-B2. I've upgraded the firmware to Marlin 2.0.9 and the case fans never turn on. When I try to start fan2 or fan3 from the marlin menu, the fan1 starts. I saw USE_CONTROLLER_FAN disabled in config files. What is the expected behavior?

My temporary solution was:

#define USE_CONTROLLER_FAN
#if ENABLED(USE_CONTROLLER_FAN)
  #define CONTROLLER_FAN_PIN FAN1_PIN 

But I am not sure if it's correct or if there's another way to configure the fans to work on demand.
