SFS V2 and Marlin 2.1.2.1 - Marlin config instructions do not match

[billg42]

I installed the SFS V2 smart filament sensor on my SKR 1.4 turbo. It is powered on with the blue light flashing as filament moves through the sensor. I've enabled the runout flags in the Marlin 2.1.2.1 configuration.h including the following lines however the remaining lines after defining FILAMENT_MOTION_SENSOR are not in the latest configuration.h file. If I enable the sensor via printer UI, I get an immediate error on the initial nozzle priming (way shorter than 3mm). Has anyone overcome this? Are there additional changes to Marlin configuration.h or in runout.h/.cpp?

#define FILAMENT_RUNOUT_SENSOR

 

#define FILAMENT_RUNOUT_DISTANCE_MM 3

 

#define FILAMENT_MOTION_SENSOR

Resolved: the runout distance configured in Marlin was 0mm. I've set it to 4 and no longer have errors.
