Marlin Configuration

Filament Runout and Blockage Function Configuration

1. Open the Marlin configuration file Configuration.h, find #define FILAMENT_RUNOUT_SENSOR, and remove the comment symbol in front of it.
2. Find #define FILAMENT_RUNOUT_DISTANCE_MM, remove the comment symbol in front of it, and set it to 3.7 (change according to the encoder used; if there is a false trigger, increase this value appropriately).
3. Find #define FILAMENT_MOTION_SENSOR, and remove the comment symbol in front of it.
4. The filament sensor function in Marlin also requires enabling #define NOZZLE_PARK_FEATURE and #define ADVANCED_PAUSE_FEATURE. Remove the comments and configure specific parameters based on your printer settings.
