• This comprehensive kit combines two essential components: the Filament Sensor (Hall Board) and the AMS Lite Filament Hub. Together they restore reliable filament detection and smooth multi‑material feeding. Replace both parts at once to eliminate intermittent errors and ensure long‑term printing stability.
• The AMS Lite Filament Hub merges four filament paths into one stable output, while the Hall sensor detects feeding resistance. This kit replaces both key parts of the detection module, ensuring your printer accurately monitors filament flow and switches materials flawlessly for multi‑color prints.
