Smart Filament Runout Sensor With Break Detection Module For 3D Printers, Compatible With Ender 3 V2, Ender 3 Pro, Ender 6, CR-10S Pro, CR-10 V2 V3, Ender 3 Max, 32Bit Board Ready, Auto Pause And Reliable Filament Monitoring

Smart Filament Runout Sensor with Break Detection
✔️ 32-bit board ready, single-pack sensor, Ender 3 v2/Pro, auto pause

This smart runout sensor monitors filament presence and detects breaks on 3D printers with 32-bit boards, automatically pausing prints when filament runs out or breaks. Compatible with Ender 3 family, Ender 6, CR-10S Pro, CR-10 V2/V3, and Ender 3 Max; kit includes the detector, extended cable, and installation bracket. Ender 3 V2/Ender 3/Ender 3 Pro require firmware flashing for proper filament detection.

✅ Independent modularized design with frosted outer cover for a clean look
✅ Filament breakage detector uses a micro switch for smooth feeding
✅ Blue LED indicates normal feed; turns off when filament runs out
✅ Compatible with 32-bit boards (firmware 4.2.2/4.2.7) and Ender 3 series; Ender 6 and CR-10S PRO use pre-mounted holes
✅ Package includes 1 filament detector sensor, 1 extended cable, 1 installation bracket for Ender 3 series

💡 What is a filament runout sensor and why is it handy for 3D printers?

A filament runout sensor helps prevent print failures by detecting missing filament and pausing the print automatically. - Filament presence detection helps avoid wasted prints - Handy for long prints and varied filaments - Works with Ender 3, Ender 6, CR-10 series when firmware includes filament detection - Improves reliability and saves material and time
