P2S - X2D PTFE Tensioner

PTFE Tensioner for P2S - X2D (CP2T)

The Tensioner eliminates guesswork when setting the Smart-Link PTFE length for P2S. It also removes the yellow choke point and allows the use of a single PTFE tube instead of two.

Can also be useful to tune PTFE length on X2S

This tensioner enables quick adjustment of the PTFE length without the need for cutting or unnecessarily wasting material.

Features

• Adjust PTFE length in seconds!
• Prevents improper tension between the toolhead guides and Smart-Link.*
• Delivers smooth, jam-free feeding by eliminating the yellow bracket restriction.

Compatibility

Compatible with Bambu Lab P2S Only

Requirement

• Screws: Refer to the screws listed in the BOM. Use them as a reference, or substitute if you don’t have compatible ones on hand.
• PTFE: Approximately 38–40 inches (1000 mm) of new PTFE. It may be cut or left as-is, depending on your preference.

Installation Instructions

1. Remove the yellow PTFE bracket.
   Refer to the guide: How to Remove the PTFE Bracket.
2. Remove Both PTFE tube from the buffer to the toolhead and completely from the unit.
3. Prepare the new PTFE tube.
   The length may vary based on personal preference.
4. Prepare the tensioner.
   Fully thread in the self-tapping screw, then back it off slightly to allow smoother movement and better control when tightening the tube.
5. Assemble the tensioner.
   Insert the lock into the tensioner body, then tighten the self-tapping screw until the lock is secured in place and cannot move.
6. Install the tensioner.
   Insert it into the printer, ensuring the PTFE tube is inserted at the same time.
7. Secure the mount.
   Once the tensioner is in position, pull the tube back slightly if needed, then insert and tighten the second screw to secure the mount to the printer.

8. Adjust the tube length.
   Pull the tube to your desired length toward the buffer, cut it and connect.

    

    

Adjustment Instructions

1. Position the toolhead at the front-right corner, at its maximum travel.
2. In the quick action shorts, you’ll see that the tube is pulled to the desired position.
3. Lock the tube in place by moving it slightly to feel resistance, then tighten the tension screw until snug.
4. Do not overtighten, as this may kink the PTFE tube and cause feeding issues.
5. Once locked in the desired position, perform a manual resistance test by feeding filament through the tube.
6. If the filament feeds smoothly and the tube is not crushed, you’re ready to print.

Maintenance – First Couple Miles Re-check

After the first few miles, re-check tension fastener.

• As the PTFE settles and slightly embosses, the locking groove may loosen, simply check and re-tighten if necessary.

Enjoy stress-free printing, no more snagged saran wrap or broken toolhead guides.
