BTT SFS V1.0 Smart Filament Sensor Detection Stuck Blocking Filament Module

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
