Anycubic SP Kobra 3 Max/Combo Extruder Components

• The Anycubic Kobra 3 Max Extruder Components Assembly: is the dual-gear direct drive mechanism responsible for feeding, retracting, and precisely metering filament into the hotend during high-speed printing (up to 600 mm/s).This module houses the hardened steel drive gear system, stepper motor integration interface, tension lever spring mechanism, and the integrated mechanical filament cutter mechanism used during multi-color filament purges with the ACE Pro system.
• Dual-Gear Direct Drive System: Utilizes hardened steel drive gears with high reduction gearing to deliver high torque, preventing filament slipping and grinding under rapid acceleration.
• Integrated Mechanical Filament Cutter: Built-in cutter lever mechanism cuts the filament tail cleanly above the heat break during automatic color changes and retract sequences.
• High Volumetric Flow Performance: Optimized gear geometry ensures smooth pushing force across flexible (TPU) and rigid high-temp filaments (ABS/PET-CF) without buckling inside the feed path.
• Adjustable Tension Mechanism: Features an adjustable tension screw to fine-tune gear grip force according to the hardness and flex of the material being extruded.

Specifications

Technical Specifications

• Compatible Models: Kobra 3 Max
• Drive Type: Dual-Gear Direct Drive
• Filament Compatibility: 1.75 mm (PLA, PETG, ABS, TPU, ASA, PET-CF, PA-CF)
• Gear Material: High-hardness hardened tool steel.

Maintenance & Care Tips

• Inspect Drive Gear Teeth Periodically: Filament dust or plastic shavings can build up between the dual gear teeth over time. Clean the gear teeth using a small wire brush or compressed air to prevent feeding slippage.
• Set Correct Idler Tension: Avoid over-tightening the tension screw on soft materials like TPU to prevent deforming the filament into an oval shape, which causes clogs inside the lower PTFE throat tube.
• Verify Cutter Blade Alignment: After mounting a replacement S010349 assembly, manually actuate the cutter lever to confirm the internal spring returns the blade fully so it doesn't obstruct incoming filament.
