100% factory fit, fully compatible with Bambu Lab A1 / A1 Mini 3D printers. Equipped with original connectors for easy plug-and-play installation.
Precision Filament Motion Detection: Featuring a high-sensitivity Hall sensor, this filament feed board precisely detects subtle filament movement in the extruder. It reliably recognizes filament shortage, breakage and feeding errors to prevent nozzle clogging, avoid print failures, and enhance printing stability and efficiency.
Optimized for multi-color printing. This PCB monitors filament feeding and retraction, and communicates with AMS Lite for seamless material switching. It also detects feed blockages and sends feedback to the printer to prevent printing errors.
Quick & Easy Installation: Simply remove the print head back cover, take apart the extruder mainboard and buffer, then replace the original Hall sensor board. A complete installation guide is available on the official Bambu Lab Wiki.
Comes with an FPC flexible cable and FR4 reinforced structure. 1.2–1.5mm thickened design enhances overall durability and structural strength.
