Filament Break Detection: Precisely monitors the filament status using a photoelectric switch, enabling real-time breakage alerts and pausing the print. Clogging and Tangling Detection: During the printing process, the encoder works dynamically with the photoelectric switch to intelligently identify nozzle clogs or spool tangles, promptly triggering a pause. Compact and : Extremely small and space-saving, compatible with a wide range of 3D printer models. Reliable Performance: Dual detection ensures print quality, reduces material waste, and improves success rates. This module combines and practicality, making it an ideal choice for enhancing 3D printing efficiency and quality.
