Product description
What it is and what it does
Alternative Hall-effect filament sensor that monitors the filament feed status in the toolhead. Helps prevent print errors (run-out, jams) and, for multi-color, passes filament in/out status to the AMS Lite system.
Compatibility and placement
- Compatible with: Bambu Lab A1, A1 Mini (A1 Series).
- Placement: the sensor (“Hall Board”) is mounted on the side of the extruder on the top of the toolhead; it installs into the Filament Sensor Base.
Package contents
- 1× Hall switch (PCB)
- 1× flexible flat cable (FFC)
Note: Reuse the original mounting screws (the OEM part uses BT2‑5).
When to replace the sensor
- The printer incorrectly reports filament presence/absence, frequent pauses due to “pull out filament”, etc.
- Damaged/torn sensor flat cable during service.
Installation – quick steps
- Power off the printer and release the top Filament Sensor Base.
- Disconnect the old FFC cable and remove the sensor from the mount, install the new one and insert the FFC into the connector.
- Tighten the screws to secure the sensor and put the base back in place.
- Perform a function check according to the official guide (Bambu Wiki).
Tip: The sensor operates on the Hall effect and the magnet of the detector lever — ensure correct orientation/installation and keep the mechanics around the lever clean.
Why choose this “alternative” part
- Functionally replaces the original FAE010 for A1 Series and comes with an FFC cable.
- Quick restoration of filament detection without waiting for a whole toolhead or service.
