About this item

The BIGTREETECH BTT SFS V1.0 is an advanced smart filament sensor designed to enhance 3D printing reliability by detecting filament issues such as runout, jamming, slipping, or breakage in real-time. Unlike basic runout sensors that only detect filament presence, the SFS V1.0 monitors the filament's actual movement and feeding status through an internal mechanical sensor coupled with signal processing technology. When the filament feeding is obstructed due to a jam, breakage, or blockage, the sensor immediately signals the printer to pause the print job, preventing failed prints, wasted filament, and possible nozzle damage. This smart sensor works effectively with various filament types, including flexible filaments that can be challenging for traditional sensors to detect accurately. Designed for easy integration, the BTT SFS V1.0 connects via a standard 3-pin interface and is compatible with popular 3D printer control boards like the SKR V1.4, SKR Mini E3, and others running firmware such as Marlin or Klipper. Its compact and sturdy design allows mounting near the extruder or filament path, ensuring reliable detection without interfering with the printing process. The BTT SFS V1.0 improves print success rates, reduces downtime, and adds peace of mind for both beginners and advanced users.
