Bambu Lab Original H2S Filament Sensor

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.
