Sensor description: https://github.com/bigtreetech/smart-filament-detection-module/blob/master/V2.0/Manual/SFS%20V2.0%20User%20Manual_20231123.pdf

The sensor allows you to stop printing not only when the filament runs out, but also when it gets tangled or clogged in the extruder.

One signal wire is connected instead of the standard sensor, and for the second signal wire, you need to either install a new connector on the main MCU board (as described in the comments to the original model) or pull the signal wire to the existing connector on the nozzle MCU.

Also, you have to change printer.cfg, for example like this:

[filament_switch_sensor filament_sensor]\npause_on_runout: false\nswitch_pin: PC15\nrunout_gcode:\n  RESPOND TYPE=command MSG=\"--- Filament broke, odnako! ---\"\n  beep\n  M600\n\n[filament_motion_sensor filament_sensor_2]\nswitch_pin: ^nozzle_mcu:PA10\ndetection_length: 7\nextruder: extruder\npause_on_runout: false\nrunout_gcode:\n  RESPOND TYPE=command MSG=\"--- Filament jammed!!! ---\"\n  beep\n  beep\n  beep\n  M600\n

Special thanks to Nikorn for the main idea.
