BIGTREETECH BTT SFS V1.0 Smart Filament Sensor – Advanced Runout & Clog Detection Module
The BTT SFS V1.0 is a smart filament sensor designed to protect your 3D prints by detecting filament runout, breakage, clogs, blockages, and motion abnormalities. Using high-precision photoelectric and motion detection, it triggers a pause within just 7mm of filament movement issues, giving you time to intervene before a failed print.
This intelligent sensor goes beyond basic runout detection. It monitors filament flow in real time, helping identify hotend jams, nozzle clogs, partial blockages, tangles, and over-constrained filament paths that cause under-extrusion. Perfect for long prints and unattended operation.
Key Features:
- Dual detection: filament presence + motion/encoder for accurate clog and runout sensing
- Fast response — detects issues within 7mm of filament travel
- Supports both Marlin and Klipper firmware
- Easy integration with BIGTREETECH motherboards (SKR series, Manta, etc.) and touchscreens
- Compact design with low friction for smooth filament feeding (1.75mm filament)
- Reliable photoelectric sensor technology
- Configurable detection distance and sensitivity
