1 Pack 3D Printer Accessories for Bambu Lab A1 Mini / A1 Feed Hall Board, Filament Sensor Replacement Kit, for Monitoring Hotend Extruder Consumables & Prevents Printing Faults

["Main Functions: The Filament Sensor Replacement Kit can monitor the status of consumables inside the extruder in real time, effectively avoiding printing failures and improving printing efficiency. It can also detect abnormal issues such as filament breakage and damage in real time.","Compatibility: This Hall sensor assembly is only compatible with A1 and A1 Mini 3D printers, and is not suitable for X1, X1 Carbon, X1C, X1E, P1P, P1S, and other series models.","Multi-filament Linkage Operation: In multi-filament printing scenarios, the integrated PCB circuit board can accurately capture the status of filament feeding and discharging, synchronize communication with the AMS Lite system, and achieve automatic filament switching. It can also monitor filament jamming issues in real time and quickly provide fault signals to the device.","Reinforced and Durable Material: Equipped with FPC flexible cables and combined with FR4 reinforced substrate, the board thickness is 1.2~1.5mm, featuring high structural strength, wear resistance, and damage resistance, ensuring a longer service life.","Easy to Install: The disassembly and assembly process is simple. Simply remove the back cover of the print head, dismantle the extrusion board and buffer components, and take off the original Hall sensor board, then you can proceed with the replacement and installation directly."]
