Specifically engineered for Creality K1C, K1 SE, K1, and K1 Max. This upgraded DXC extruder offers a seamless fit without requiring any firmware rooting. The brand-new dual-drive structure doubles the contact area, providing massive grip to prevent slippage. This synchronized system effectively eliminates vertical lines (VFA) on your prints, ensuring stable and continuous feeding even during high-speed tasks. The Adaptive Rocking Arm automatically adjusts pressure based on filament hardness, while the built-in Smart Detection system monitors feeding in real-time. This combo prevents filament waste and mess during runouts or multi-material switches.
