Creality CFS lite buffer assembly

The Creality CFS lite buffer assembly is the filament buffer unit of the CFS lite multi-filament box for the SparkX i7 3D printer. The assembly is installed close to the filament outlet of the CFS lite and supports smooth filament transport between the feeding unit and the SparkX i7 toolhead. Inside the buffer are a photoelectric sensor and a compression spring connected to a black structural block. This combination forms the so-called filament entanglement detection module, which automatically detects filament tangles during printing or filament loading.

Features:

• Photoelectric sensor and compression spring together form the filament entanglement detection module
• Automatically detects increased feed resistance due to filament tangles on the spool
• Black structural block triggers the photoelectric sensor and sends an alarm signal in case of excessive resistance
• Stops printing in time before further print errors occur due to filament tangles
• Sits close to the filament outlet of the CFS lite and works in conjunction with the feeding unit
• Original replacement part from Creality, exclusively compatible with the CFS lite and SparkX i7 system

Application Examples:

• Replacement after failing to detect filament tangles leading to subsequent print interruptions
• Repair in case of recurring tangle alarms triggered without an actual problem
• Maintenance after mechanical damage to the buffer spring mechanism
• Stock as a spare part in print workshops and print farms with multiple CFS lite units
• Recommissioning after service interventions in the filament outlet area of the CFS lite
