Product Description

The original Bambu Lab Dual Extruder Idlers and Filament Sensor (FAE024-V1) is a replacement set of pressure rollers and a filament sensor for the dual extruders of Bambu Lab H2D / H2C printers. Together with the drive gear, it firmly grips and moves the filament, ensuring stable and precise extrusion even at high printing speeds.

In the dual extrusion system, the module switches between two filament paths, so it seamlessly handles multi-color printing and printing from different materials. The integrated filament detection sensor monitors the presence of the strand and prevents the ruin of a work-in-progress print if the material runs out or feeding fails.

Main Advantages

• Stable filament feeding – pressure rollers firmly guide the filament to the drive gear and minimize slippage.
• Integrated filament sensor – detects the presence / end of filament and helps prevent empty printing.
• Support for multi‑color and multi‑material printing – allows automatic switching between two filament inputs in the dual extruder.
• Original Bambu Lab part – full compatibility and reliability, identical to the OEM equipment of H2D / H2C printers.
• Easy replacement – the set includes the necessary mounting screws, installation is a matter of minutes.
• Compact and lightweight design – precisely designed for the space in the Bambu Lab H2 extruder unit.

Usage

The set is suitable as:

• spare part in case of wear or damage to the original rollers or sensor,
• prevention for intensively used printers (farms, production printing),
• solution for filament feeding problems, slippage, irregular extrusion, or frequent filament detection errors.

Recommended for users who print in multi-color, with multiple materials, or use AMS, where reliable filament switching is key.

Compatibility

The Bambu Lab Dual Extruder Idlers and Filament Sensor (FAE024-V1) set is intended for Bambu Lab H2 series printers:

• Bambu Lab H2D
• Bambu Lab H2D Laser
• Bambu Lab H2D Pro
• Bambu Lab H2C
• Bambu Lab H2C Laser

Note: This is not a universal component for other Bambu Lab models (X1, P1, etc.). Before ordering, verify that you have an H2D / H2C series printer.

Package Content

• 1× Dual Extruder Idlers and Filament Sensor (complete module)
• 2× screw BT2‑5
• 2× screw MG2.5‑19.5

Everything is delivered in a compact package ready for direct assembly.

Technical Parameters

Installation and Maintenance

• Before replacement, turn off the printer and let the hotend cool down.
• Follow the official Bambu Lab manual (maintenance section – replacement of Dual Extruder Idlers and Filament Sensor).
• Check the cleanliness of the filament path and gears, remove any material residue.
• After replacement, perform a filament feeding test and a test print to verify smooth extrusion and correct sensor function.

A properly functioning idler + filament sensor is essential for reliable, long-term, and unattended operation of Bambu Lab H2 series printers, especially in combination with the AMS automatic feeding system.
