Anycubic SP Kobra 3 max/combo Quick Release Hotend with 0.4mm Nozzle

• The Anycubic Kobra 3 Series / Kobra 3 Max Quick Release Hotend with 0.4mm Nozzle is the official OEM quick-swap thermal melting unit engineered for the Kobra 3, Kobra 3 Combo, and Kobra 3 Max 3D printers. Designed to support fast printing speeds (up to 600 mm/s) and multi-color tool changes with the ACE Pro system, this unit combines an all-metal thermal break, ceramic heating core, and a quick-release locking mechanism into a lightweight assembly.
• Lever-Lock Quick-Release System: Utilizes a dual-spring lever locking mechanism that allows users to swap hotends or nozzle sizes in seconds without tools, heat-tightening, or disassembling the toolhead.
• 300°C High-Temperature Rating: Equipped with an aerospace-grade ceramic composite throat tube and all-metal hotend block rated up to 300°C, accommodating PLA, PETG, TPU, and engineering-grade filaments like ABS and ASA.
• High-Flow Thermal Response: Incorporates a high-power wrap-around ceramic heating block for rapid thermal recovery during high-speed printing (up to 600 mm/s) and fast preheating routines.
• Standard 0.4 mm Brass Nozzle: Integrated factory 0.4 mm nozzle size optimized for standard layer heights (0.12mm – 0.28 mm) and default Anycubic Slicer profiles.
• Pre-Assembled Assembly: Comes complete with pre-installed thermistor, heater wiring harness, quick-connect terminal plug, and a silicone insulating boot.

Maintenance & Care Tips

• Wait for Cool-Down: Always allow the nozzle temperature to drop below 40°C before engaging the lever lock to replace the unit to avoid burns.
• Keep the Silicone Sock Attached: Always keep the custom black silicone insulator installed over the heating block. Operating without the boot lets cooling airflow from the part fans destabilize temperature readings, causing thermal runaway errors.
• Run PID Auto-Tuning: After swapping to a new module, perform an Auto PID Calibration from the touchscreen menu to calibrate temperature response for tight temperature control.
