Smart Filament Sensor Kit for Ender 3 V3 SE/KE, Smooth Feed Path, Quick Installation Design

Filament Detector Kit for Ender3 V3 SE and Ender3 V3 KE Product overview A compact filament sensor and guider designed for Ender3 V3 SE and Ender3 V3 KE printers. The unit detects filament presence and provides a smooth feed path to reduce feeding friction, helping avoid print interruptions caused by filament runout or poor filament guidance. Key benefits Reliable filament detection: Blue LED indicates normal filament feedin. The LED turns off when filament runs out, giving a clear visual signal of filament status. Smoother filament feed: Builtin filament guider is made of metamaterial with a smooth surface to reduce friction and support steady filament movement. Simple installation: Straightforward structure for quick assembly and installation, allowing fast setup on compatible printers. Compact and lightweight: Small footprint and low weight make it easy to add without affecting printer balance or workspace. Main features Function: Filament detection with visual LED indicator and integrated filament guide Material: Plastic plus electronic components Compatibility: Only compatible with Ender3 V3 SE and Ender3 V3 KE printers Package dimensions: 21.5 x 14.0 x 5.5 cm Product weight: 180 g Package contents: Filament Detector Kit x1 Practical use scenarios Long prints: Monitor filament during multihour or overnight prints so you can spot runout quickly and prevent wasted print time. Filament changes: Use the detector when switching spools to confirm the filament is feeding correctly before resuming a print. Troubleshooting feed issues: Install the guider and sensor to diagnose and reduce filament slipping or snagging in the feed path. Notes on installation and operation Designed for quick assembly with the original printer structure in mind. Follow printerspecific mounting and wiring steps for correct operation. The blue LED provides a clear indicator of filament presence; no additional tools are required to see feed status. This kit provides a practical filament sensing and guiding solution for users of Ender3 V3 SE and Ender3 V3 KE printers who want a simple way to monitor filament feed and reduce interruptions.
