Smart Filament Sensor (SFS V1.0)
The smart filament sensor works by continuously sending signal to the mainboard
to communicate filament status.
#define FILAMENT_MOTION_SENSOR // set encoder type
#define FILAMENT_RUNOUT_DISTANCE_MM 7 // set sensitivity, SFS V1.0
nominal setting should be 7mm, which means if no signal of filament movement is
detected after 7mm of filament travel command, filament error will be triggered.
The settings below also need to be set to instruct the printer to park the nozzle
after filament error is detected.
