Description
The i7 Extrusion Assembly is the core component responsible for filament feeding, retraction, and material control within the printer's toolhead layout. It functions as a complete, drop-in replacement housing that unifies Creality’s high-torque dual-gear drive trains, localized filament tracking sensors, and structural mounting points.
Engineered to support high-acceleration CoreXY movements and high-speed printing workflows, this assembly provides consistent, slip-free feeding for standard, flexible, and composite filaments alike. It serves as an essential direct replacement if your original extruder housing experiences internal gear wear, electronic sensor failure, or structural damage from long-term, continuous production runs.
Features
Dual-Gear Direct Drive System: Utilizes precision-machined, hardened dual-drive gears that grip filament tightly from both sides, minimizing slippage and enabling high-volumetric extrusion rates.
Integrated Sensor Matrix: Pre-fitted with localized internal sensors, including an automated filament runout tracking module that communicates seamlessly with the printer's motherboard.
Multi-Color Switching Optimization: Designed to interface perfectly with the CFS Lite multi-material manager, accommodating rapid, frequent loading and unloading cycles without grinding the filament.
True Drop-In Replacement: Complete with pre-routed wiring harnesses and factory-keyed quick-connect pin terminals, eliminating the need for soldering or wire splicing during installation.
Lightweight, Rigid Housing: Constructed from a high-impact, heat-resistant composite material that minimizes extra weight on the X-axis gantry to reduce ghosting and ringing at high print speeds.
