Update — Mar 30

We’ve made several improvements to help with flexible filament printing and overall setup:

1. TPU-Optimized Spool Holder Added
A new spool holder model (with G-code files) is now available, designed specifically for TPU and other flexible filaments.
Due to their feeding characteristics, using the standard spool holder may affect performance. For better results, we recommend switching to this spool holder when printing flexible materials.

2. Installation Guides Updated
Instruction images and videos have been updated to reflect the new spool holder setup, making the installation process clearer.

3. Improved Instructions
We’ve corrected some text and added missing details, including guidance for disconnecting the CANVAS cable.

Tip:
If you experience feeding issues or instability when printing TPU, try using the new spool holder along with this adapter for more consistent results.

Update — Mar 9
We have added a video guide to help explain the model and installation process.
Please watch the video below for a quick overview and step-by-step setup.

Since TPU filament has specific requirements for retraction and feeding, it is not recommended to use the standard spool holder directly. We will upload an additional spool holder model optimized for TPU shortly—stay tuned!

A practical adapter for the Centauri Carbon 2 Combo that improves handling of TPU and other flexible filaments, ensuring more reliable prints. It helps reduce jams and enhances print consistency, making flexible material printing accessible for both beginners and experienced users.

Additional Information & Instructions
1. Compatible Printer: Designed for the Centauri Carbon 2 Combo
2. Printing Material (for the adapter itself): PLA
3. Compatibility Notice: This adapter is not compatible with the top cover and cannot be used while the top cover is installed.
4. Tube Configuration
• The long PTFE tube (approx. 48mm length specification as provided, 4 mm inner diameter) should be inserted into Canvas Channel 1 (upper inlet).
• The short PTFE tube (approx. 25mm length specification as provided, 4 mm inner diameter) should be installed at the bottom of the adapter.
Please ensure both tubes are firmly seated to prevent filament feeding issues.

Recommended Use Case
This adapter is specifically designed for printing flexible filaments such as TPU.
It improves filament guidance and feeding stability, reducing the risk of buckling and jams during printing.

How to Use
1. Single-Color Printing
• Disconnect the CANVAS cable.
• Feed the filament through the PTFE tube located at the bottom of the adapter.
2. Multi-Color Printing
• Feed the filament through the PTFE tube below Canvas Channel 1, following the standard multi-color printing workflow.
• The setup remains the same as regular multi-color printing.

Removal Instructions
When removing the adapter:
1. Use flush cutters (side cutting pliers) to carefully remove the support structure if necessary.
2. Insert the tool into the U-shaped slot below Channel 1 to gently loosen the connection point between the adapter and the CANVAS lower latch.
3. Remove the adapter from the top of the T-joint.
4. Reinstall and restore the CANVAS module to its original configuration.
