Generic Filament Sensor Strip for Bambu Lab P2S

Generic Filament Runout Sensor Strip for Bambu Lab P2S

Overview

A replacement filament sensor for the Bambu Lab P2S. It sits in the upper section of the extruder assembly and keeps track of whether filament is feeding in or has run out during a print. Use it to fix failed feed detection, a broken internal component or an aging wire fault on the stock sensor.

Key Features

• Made specifically for the Bambu Lab P2S

• Replaces a faulty or worn feed detection sensor

• Monitors filament feed and runout in real time while printing

• Works with the original AMS, recognising filament being inserted and pulled out so multi-colour switching stays smooth

• Comes with the mount screw and a matching H1.5 hex wrench for a quick swap

Compatibility

• Bambu Lab P2S only

• Not compatible with X1, X1C, X1E, P1P, P1S, A1, A1 Mini or other series

Installation

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