Anycubic Kobra 2 Neo Review

The Anycubic Kobra 2 Neo is equipped with a proprietary PTFE-lined hotend. Let’s delve into its performance characteristics:

  1. Heating Speed and Clogging:

    • The stock hotend heats up slowly and is susceptible to clogs.
    • Its flow rate is approximately the normal volcano flow rate (around 20 mm^3/s with a 0.4mm nozzle).
    • Unfortunately, due to its proprietary design, it cannot be upgraded with a CHT or CHT clone nozzle.
  2. Kobra 2 Neo Specifications:

    • Printing Size: The Kobra 2 Neo offers a standard printing size of 220mm x 220mm x 250mm.
    • Print Speed:
      • Recommended: 150mm/s
      • Maximum: 250mm/s
      • It can complete a Benchy model in less than 30 minutes.
  3. Advantages:

    • High-Speed Printing: With a remarkable maximum print speed of 250mm/s, it balances precision and performance.
    • Suitable for beginners and those seeking a cost-effective solution.
  4. Minor Quibbles:

    • The PEI bed surface is aggressive, ensuring prints stick well, but the underside of the print may be a little rough.
    • The print cooling fan can be quite loud when running at full speed.
  5. User Experiences:

    • Some users have upgraded their Kobra Neo with Klipper and Linear Rails, resulting in impressive speed and quality improvements. However, fast prints may occasionally exhibit a crunchy texture or filament feeding issues.

Low-Cost Maintenance Tips for Anycubic Kobra 2 Neo Hotend

Proper maintenance of your Anycubic Kobra 2 Neo hotend is essential for consistent and high-quality 3D printing. Here are some low-cost maintenance tips to keep your printer in top shape:

  1. Clean and Tighten Your Nozzle:

    • The nozzle is a critical component that extrudes molten filament. Regularly check for clogs caused by temperature fluctuations or poorly-made filaments.
    • To clean the nozzle:
      • Unplug the power source.
      • Use a brass wire brush or needle to remove residue.
      • Alternatively, perform a “cold pull” by inserting a needle into the nozzle under preheating conditions.
      • Wipe the nozzle with a cloth.
    • Ensure the nozzle is properly tightened to prevent plastic oozing and print quality issues.
  2. Remove Rust and Lubricate Moving Parts:

    • Lubricate guide rails, rods, lead screws, and extruder gears to reduce friction, wear, and noise during operation.
    • Steps:
      • Apply grease to a cotton cloth.
      • Wipe moving components back and forth to remove dust and rust.
      • Squeeze grease directly onto linear rails and rods.
      • Control all axes to evenly coat them with oil (avoid excessive grease).
  3. Check Belts and Pulleys:

    • Belts and pulleys are vital for motion on the X and Y axes.
    • Use Allen keys and screwdrivers to adjust tension.
    • Properly tensioned belts ensure accurate prints and prevent damage.
  4. Monitor Hotend Temperature and Filament Flow:

    • Regularly check the nozzle temperature and adjust it to the optimum for the filament material.
    • If the nozzle is blocked by debris or filament, unclog it using appropriate tools (be cautious of high temperatures).
  5. Replace the Hot End When Necessary:

    • A worn-out or malfunctioning hot end can lead to issues like clogs and poor layer adhesion.
    • Follow the manufacturer’s instructions to replace the hot end effectively.
