Description/Features: The quintuple assembly is used to switch filaments during multi-color or multi-filament printing. One end of the quintuple assembly connects to 4 different tubes (up to 4 filaments), while the other end connects to the top of the extruder for feeding. Function of 4-in-1 PTFE Connector (applicable to X1/P1/A1 series +): 1. Main function: This connector is a key component for multi-material printing (MMU, Multi-Material Unit), used to connect the Automatic Material Switching System and the printer hot end to enable automatic switching of 4 different colors or materials. 2. Specific function: Merges 4 PTFE tubes into 1, allowing 4 materials to enter the hot end through a single path. 3. Applicable models: X1/X1C (required); P1P/P1S (required); A1/A1 mini (Lite required). 4. Common issues: - Material switching failure? Check if the connector is loose or if the PTFE tube is worn. - Material jam or blockage? Ensure the connector is properly aligned with the hot end to prevent bending. 5. Other devices: Not tested; please confirm your device supports multi-color material change functionality.
