  5. Direct Filament Feed:

    • Some users have reported improved reliability by bypassing the Bowden tube altogether. By feeding filament directly to the extruder, they’ve experienced fewer failures. You might want to explore this option as well .

Creality K1 Max Bowden Tube Features

The Creality K1 Max 3D printer features a reverse Bowden tube that guides the filament from the runout sensor near the spool holder, up the side of the frame, and across the top to the extruder. Unlike traditional Bowden tubes, which transfer force through relative pressure differential, this guide tube serves as a filament pathway without pressure differences. Here are some details related to the Bowden tube on the Creality K1 Max:

  1. Bowden Tube Removal: Some users have reported improved reliability by removing the Bowden tube and directly feeding filament to the extruder. This modification has led to fewer failures and easier filament changes. If you’re experiencing issues like under extrusion, clogs, or extruder jamming, you might consider trying this approach.

  2. 90-Degree Bend: To prevent the Bowden tube from rubbing under the lid and ensure smoother cable chain movement, a 90-degree bend can be added. This bend is designed to be loose enough to avoid causing under extrusion problems.

  3. Acrobatic Bowden Tube Guide: Another creative solution is the K1 / K1 Max Acrobatic Bowden Tube Guide, which allows filament routing even when the spool is moved to the left side of the K1 Max. This guide is designed with an acrobatic shape and can be used with or without the original spool placement at the back.

Troubleshooting Creality K1 Printer Bowden Tube Issues

Troubleshooting Creality K1 printer issues related to the Bowden Tube can be crucial for achieving optimal print quality. Here are some common problems and potential solutions:

  1. Underextrusion:

    • Quick Fix: Remove the Bowden Tube from the drag chain. This video demonstrates the process: .
    • Additional Considerations: Ensure that the tube is not kinked or warped, as this can cause resistance for the extruder. If you suspect a bad PTFE tube, consider replacing it.
  2. Filament Jamming:

    • Causes:
      • Material entanglement in the filament spool area.
      • Blockage in the extruder front casing.
      • Clog in the PTFE tube inside the extruder.
      • Nozzle blockage.
      • Accumulation of material debris in the extruder gears.
    • Solutions:
      • Inspect connections between the nozzle adapter board and the hotend sideboard.
      • Reconnect wires securely.
      • Regularly clean the nozzle and PTFE tube.
      • Check for any obstructions in the extruder gears.
  3. Bowden Tube Removal:

    • Some users have reported improved reliability by removing the Bowden Tube and feeding filament directly to the extruder.
    • Benefits:
      • Easier filament changes.
      • Reduced resistance for the extruder.
    • Note: Be cautious and test before committing to cutting out the tube.

Advantages of Removing Creality K1 Max Bowden Tube

The Creality K1 Max Bowden Tube offers several advantages over the standard tube. Let’s explore these benefits:

  1. Improved Filament Flow and Reliability: Some users have reported that removing the Bowden Tube and directly feeding filament to the extruder significantly improved reliability. After making this modification, they experienced fewer failures related to under-extrusion, clogs, or extruder jamming. The absence of the tube seems to reduce resistance for the extruder, resulting in smoother filament flow.

  2. Easier Filament Changes: Without the Bowden Tube, filament changes become dramatically easier. By running the retract routine, unlocking the extruder, and sliding off the filament, users can swiftly switch materials or colors. This convenience is especially beneficial for those who frequently change filaments.

  3. Potential Issues with Stock PTFE Tubes: Some users suspect that the stock PTFE tube (which is part of the Bowden system) may contribute to problems. Tight bends and warping in the tube could increase resistance for the extruder. Removing the tube eliminates this potential issue.

  4. Clarification on Terminology: It’s essential to note that the component in question is not technically a “Bowden tube.” A true Bowden tube transfers force through relative pressure differential, but in the case of the K1 Max, there is no such pressure difference between the tube and filament. Instead, it serves as a guide tube. So, while some refer to it as a Bowden tube, it’s more accurately described as a guide tube.

In summary, removing the Bowden Tube from the Creality K1 Max can lead to smoother filament handling, easier maintenance, and potentially better overall performance. However, individual experiences may vary, and users should consider their specific needs and preferences when deciding whether to make this modification.
