Creality CFS Lite Buffer Assembly for SPARKX i7 Automatic Filament System, Official Buffer, Integrated Photoelectric Sensor Tangle Detection Module, Original 3D Printer Part

Durable and Reliable: This is an authentic Creality spare part, designed specifically for the SPARKX CFS Lite automatic filament management system. Engineered for continuous operation with minimal wear, supporting extended print sessions Compact & Perfect Fit for CFS Lite System: With overall dimensions of just 77×21×32mm Smart Tangle Detection – Protects Every Print: Built‑in photoelectric sensor + spring + black structural block form a precision filament tangle detection module. This prevents “air printing” or failed prints Smooth Feeding – No More Jams or Grinding: The spring not only triggers the sensor but also provides physical buffering. When high resistance is detected, the buffer still holds enough filament for the extruder to consume briefly, avoiding layer inconsistency or printing defects caused by sudden feeding stops Dual Protection – Anti‑Tangle & Anti‑Grinding: When filament gets tangled or knotted on the spool, the buffer quickly detects abnormal feeding resistance and triggers a system alarm. In case of “grinding” (the feed gear wears a groove in the filament, causing idle spinning), the system also sends a prompt
