Bambu Left Eddy Sensor — X2D (FAC205)

Official Replacement Sensor • Active Filament Flow Calibration • Genuine Bambu Lab Part

Overview

The Bambu Left Eddy Sensor (FAC205) is the official replacement eddy current sensor for the left nozzle of the Bambu Lab X2D. Installed between the left hotend and the extruder, it enables the printer's active filament flow calibration system, helping maintain accurate extrusion, consistent print quality, and reliable first-layer performance.
