How to Install Capricorn Bowden Tube on Ender-3 V3

To correctly install the KE Bowden Tube in your Ender-3 V3, follow these steps:

1. Remove the Old Tube:

   • First, depress the retaining ring on the cold end coupler (where the tube connects to the extruder).
   • Push the Bowden tube further into the coupler to disengage the internal sprung clip.
   • This should allow you to remove the old Bowden tube.

2. Prepare the New Capricorn Bowden Tube:

   • If you’re using a Capricorn Bowden Tube, make sure it’s the correct length for your printer.
   • To install the tube in spring-loaded fittings, push down on the collar and insert the end of the tube.
   • For C-clip fittings, insert the tube and then pull the collar out (you can use needle-nose pliers or a screwdriver).
   • Insert the C-clip to keep the tube in place .

3. Install the New Tube:

   • Align the Capricorn Bowden Tube with the extruder and hotend.
   • Secure it in place according to the type of coupling you have (spring-loaded or C-clip) .

Remember to double-check

Troubleshooting KE Bowden Tube Issues on Creality Ender-3 V3 3D Printer

If you’re experiencing issues with the KE Bowden Tube on your Creality Ender-3 V3 3D Printer, here are some steps you can take to troubleshoot:

1. Depress the Retaining Ring:

   • First, locate the cold end coupler where the Bowden tube is connected.
   • Depress the retaining ring (usually a small circular clip) that holds the Bowden tube in place.

2. Push the Bowden Tube Further In:

   • While holding down the retaining ring, gently push the Bowden tube further into the coupler.
   • This action should disengage the internal sprung clip and allow you to remove the Bowden tube.

3. Quality of Pneumatic Couplings:

   • Keep in mind that the quality of pneumatic couplings matters.
   • Good-quality couplings should allow for multiple insertion and removal cycles.
   • However, some couplings used by Creality printers have a reputation for early failure.

Remember to follow the manufacturer’s guidelines and safety precautions while troubleshooting. If the issue persists, consider seeking additional support or consulting the comprehensive troubleshooting guide provided by Creality

Optimizing Bowden Tube Performance

Optimizing the Bowden Tube performance in your Creality Ender-3 V3 can significantly enhance your 3D printing experience. Let’s explore some advanced techniques to achieve better results:

1. Direct Drive Extruder Conversion:

   • Consider upgrading to a direct drive extruder. This modification improves filament feeding, reduces clogging, and enables the use of flexible filaments. The E3D Hemera Direct Drive Kit is a popular choice for Ender 3 models.
   • Direct drive systems reduce the distance between the extruder motor and the hot end, resulting in better responsiveness and more accurate filament control.

2. Bowden Tube Security:

   • The Bowden tube connects the extruder to the hot end. Ensuring its stability is crucial.
   • Temporary Fix: Use a zip tie or thin strips to secure the Bowden tube and prevent it from popping out of the extruder.
   • For a more permanent solution, consider upgrading to a high-quality Capricorn PTFE Bowden Tubing Kit.

3. Check Inner Diameter:

   • The stock Bowden tube’s inner diameter may impact filament flow. Some users find that the Ender 3’s tube is narrower, which can be advantageous for flexible materials.
   • Upgrading to a Capricorn or similar high-quality tube with a slightly smaller inner diameter (e.g., 1.9 mm) can improve performance.

4. Firmware and Settings:

   • Ensure your printer’s firmware is up-to-date. Firmware upgrades often include bug fixes and new features.
   • Adjust settings like retraction, linear advance, and E-jerk to optimize filament flow and reduce stringing.
   • Experiment with different values to find the optimal configuration for your specific setup.

In conclusion, the Creality Ender-3 V3 KE Bowden Tube is a key component that significantly impacts the performance of your 3D printer. By following the maintenance tips outlined in this article and considering advanced techniques like direct drive extruder conversion and Bowden tube security upgrades, you can ensure optimal filament flow and smoother printing processes. Remember, proper care and attention to the Bowden tube can make a world of difference in achieving high-quality prints with your Ender-3 V3 KE.

Stay informed, stay proactive, and unleash the full potential of your 3D printing endeavors.
