Product introduction:BIGTREETECH SFS V2.0 smart filament sensor is upgraded of BTT SFS V1.0, BTT SFS V2.0 is adopts high precise adopts photoelectric sensor whose theoretical detection length can reach up to 2.88mm, much shorter than 7mm of SFS V1.0. more accurate detection, detecting nozzle clogging, filament runout, filament tying, and extruder malfunctions, filament run s out or is broken, upgraded Bi-Directional Feeding, Status Light. It is the ideal choice for the 3D printer lamp to run/break detection module on the market.

Calibration method :

1. The theoretical detection length of 2.88mm is the amount of filament that will be extruded between each pulse of the signal. This means that if no filament movement signal is detected after 2.88mm of filament travel command, a filament error will be triggered.  

2. Setting the detection distance to exactly 2.88mm may likely cause false triggers or errors. You can treat this parameter as the sensitivity of the sensor, the higher the number, the less sensitive the sensor will be.  

3. The detection length needs to be adjusted depending on the mounting location of your SFS V2.0. The further away from the extruder, the higher the number will need to be. We recommend a starting point of 3mm. If you keep getting false triggers, increase the detection length by 1mm increments until the problem is resolved.
