FAN0_PINPC6 part cooling fan
FAN1_PINPC7 extruder auto cooling fan
24V always on controller fan
The controller fan in the SUNLU T3 is hardwired to PSU power in a port marked as 24V on the printer so it is on whenever the printer is on. CONTROLLER_FAN_PIN in pins_BTT_SKR_MINI_E3_V2_0.h can be commented out or redefined to -1 to prevent the default FAN1 from activating as the controller fan.
Benefits
Allows SUNLU T3 users to compile the latest Marlin for the printer instead of the modified SUNLU firmware based on Marlin 2.0.8.
This enables bed PID control, input shaping, and correctly maps the extruder auto cooling fan to the right fan instead of setting the extruder cooling fan as the controller fan (which is a separate fan that is always hardwired on).
Description
Added a new configuration for SUNLU T3 printer.
