Currently there is no way to detect filament feed problems.
Solution
Filament runout sensors are commonplace, and new optoelectronic versions are more versatile & capable than simple switch-based sensors.
Considering how expensive the feed failures have been with Ultem and other high tech polymers this is an essential workflow upgrade.

Detecting More than Just Runout
Upon detecting nozzle clogging, filament runout, filament tying, and extruder malfunctions, SFS V2.0 will promptly issue error alerts on the screen and automatically pauses printing. This prevents unnecessary resource wastage.
Real-Time Status Indication：Easily know the filament status at a glance
Normal Printing:The blue light flashes during smooth printing when the printer and filaments are functioning properly.
Filament Runs out or is Broken:steady red light prompts the user to rapidly respond to a filament shortage or breakage.
Others：Nozzle Clogging/Extruder Trouble/FilamentTyingA steady or extinguished blue light.
Bi-Directional Feeding
Its unconstrained filament direction eliminates concerns over orientation,enabling quick,easy installation and flexible positioning to maximize space.
Highly Precise Photoelectric Sensor
Theoretical Detection Length：2.88mm
Lighter and Smaller：Enhances installation ease and space use without overburdening direct-drive extruders，preserving printing speed and accuracy.
SFS V2.0 weighs 36g,40% less than V1.0 and 35.95% smaller.The 36g excludes the Bowden tube connectors.
Wide Compatibility：Supports any motherboard with available I/O ports(Endstop,Filament detection,BLTouch,Induction sensor,etc)
Unique and Cool：Merges cool aesthetics，with utility,enhancing your 3D printing experience.
