SFS V1.0 smart 3D filament detection sensor

Avoid failed prints using this quality 3D filament run-out sensor on your 3D printer. In only seven millimeter it will detect a filament run-out and pause your 3D printer to avoid disaster, so you have time to insert a new filament spool. This also allows you to use the last bit on a filament spool without worry, to reduce your waste. The sensor is compatible with the SKR mini E3, SKR E3 DIP, SKR V1.3, MKS GEN L, MKS GEN V1.4, but can work with any main board and firmware that supports a detection sensor.
