Description
The i7 Extruder Gear Assembly is the mechanical heart of the filament feeding system. Positioned inside the main direct-drive toolhead, this dual-gear assembly directly grips the filament to push it into the hotend or pull it back during retractions.
Over months of high-speed printing—especially when running abrasive filaments like carbon fiber, glass fiber, or glow-in-the-dark blends—standard extruder gears can dull, collect plastic debris, or wear down. This can lead to issues like filament slippage, under-extrusion, or ghost tracking. Swapping in this factory-fresh gear core completely restores the printhead's original mechanical bite and precise volumetric feeding.
Features
Hardened Dual-Drive Grip: Precision-machined from a hardened steel alloy to resist wear from abrasive composite filaments while providing dual-sided traction on the filament strand.
Sharp, Non-Slip Tooth Profile: Features custom-cut teeth designed to bite cleanly into standard $$1.75\text{ mm$$ materials without grinding or deforming flexible filaments like TPU.
Integrated Needle Bearings: Equipped with pre-lubricated internal needle bearings that ensure smooth, concentric rotation under high tension, reducing friction on the stepper motor.
Essential for Multi-Color Setups: Restores the consistent loading and high-speed retraction performance required for frequent material swaps when using the CFS Lite switcher.
Complete Core Assembly: Comes pre-assembled with both primary and secondary driven gears, a central alignment shaft, and a high-tension spring hinge arm for quick installation.
