Bambu Lab Original Extruder Filament Sensor for Bambu Lab H2S and H2S Laser
Overview
This replacement filament sensor sits inside the extruder of your Bambu Lab H2S. It detects whether filament is present and also senses the position of the filament cutter lever, so the printer can load, unload and cut filament correctly. Replace it if your printer reports filament sensor faults or fails to detect filament in the extruder.

Power off and unplug the printer before starting any work on the extruder or toolhead electronics.

Handle the black FPC cable gently and make sure it is not pinched near the screw hole when you refit the sensor.
After installing, power the printer back on and test loading and unloading filament on the screen to confirm it works.
