Creality SP Ender-3 V3 KE / SE Filament Detector

An optical filament runout and breakage sensor designed for the Ender-3 V3 KE and SE series. It monitors filament presence and pauses or stops the printer when a spool runs out or the filament breaks, helping to prevent failed prints. The module fits inline with the filament path and connects directly to the printer’s control board.
