This smart filament sensor designed by BigTreeTech will detect a filament run-out with just seven millimeters left. It will pause your print so you have time to insert a new spool. This sensor is great to reduce waste, because it will allow you to use last bit of filament left on your spool. The sensor is compatible with 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.
