Restore Your Bambu Lab H2D or H2C Dual Extruder with the Original Idler and Filament Sensor Assembly Does your H2D or H2C show filament jam errors, fail to detect filament, or have inconsistent extrusion on one or both nozzles The original Dual Extruder Idler and Filament Sensor Assembly is the genuine OEM factory part designed exclusively for the H2D and H2D and H2C C to restore proper filWhat Is the Dual Extruder Idler and Filament Sensor Assembly This original component is installed inside the extruder assembly of your H2D or H2C dual nozzle printer. each extruder and Send real time status to the printer control system. Core Functions and Benefits Function One Reliable Filament Feeding The idler wheels work together with the extruder drive gears to push filament forward during printing. Function Two Filament DetThe sensor detects when filament is present in the filament path and signals the printer. jam errors even When the idler wheels lose tension, the printer may fail to feed filament and report a jam. This genuine OEM assembly solves both problems by replacing worn idlers and faulty sensors together. Function Four Essential for Dual Extruder Maintenance The H2D and H2C extruder system has multiple moving parts that wear over time. replacement. This complete assembly Give you everything needed for a full extruder idler rebuild on both extruders simultaneously. Function Five Factory Original Quality with Correct Screws This OEM spare part includes the idler assembly plus the exact screws required for installation: two BT2x5 screws for the Hall sensor cables and two M2.5x19x5 screws for securing the assembly.
