Install the 2.20 Hotend on your Bambu Lab P1P / P1S & X1 / X1C / X1E

More control, maximum stability, and zero drama with flexible filaments.

1. Introduction

This isn’t just a new nozzle. It’s the Filaflex 2.20 System: a larger internal diameter designed to prevent flexible filaments from compressing and losing drive. In this guide, we will transform your Bambu Lab P1S/P1P or X1/X1C/X1E to print flexibles with industrial stability while maintaining 100% compatibility with standard 1.75mm rigid filaments.

🟢 INFO: Useful technical background.

🔵 PRO TIP: Expert technical advice.

🔴 SAFETY: Mandatory stop to avoid accidents.

3. Step by Step Hardware Installation

Follow this detailed sequence to integrate the Filaflex 2.20 system into your Bambu Lab P1P/P1S & X1/X1C/X1E. Each step is designed to ensure precision and ease of assembly. We will begin by accessing the toolhead, followed by the specific adjustments that unlock industrial-grade flexible printing. Take your time, follow the icons, and transform your machine into a high-performance flexible powerhouse.
Step 1: Unload & Power Down

Action 1: Unload the filament from the menu.

 Image

Action 2: Manually lower the print bed to create enough space to work comfortably.

 Image

Action 3: Turn off the power switch at the back and unplug the power cord.

 Image
Step 2: Access

Open the front door and move the toolhead to the side to gain better access.

 Image

🔴 SAFETY: Ensure the hotend is completely cold before proceeding.
Step 3: Magnetic Cover & Fan

The front cover is magnetic; pull it gently to remove it.

 Image

🔴 SAFETY: The part cooling fan is attached to this cover. Carefully disconnect the plug without pulling on the wires.
Step 4: Disconnect Sensors

Disconnect the two main hotend connectors: the temperature sensor (thermistor) and the ceramic heater.

 Image

🔵 Pro Tip: Take your time to identify the small tabs on the connectors to avoid forcing them.
Step 5: Remove Original Hotend

Using the Allen key, loosen the two screws holding the hotend in place and remove the unit.

 Image

🔵 PRO TIP: Keep these screws in a safe place; you will need them to install the new 2.20 hotend later.
Step 6: The Tension Screw Window

Locate the screw: Look through the side of the toolhead to find the extruder tensioner screw.

 Image

Mark the center: Use a permanent marker to pinpoint the screw's center on the plastic housing.

 Image

Draw the triangle: Measure 5mm above and 5mm below the center point to draw an equilateral triangle.

 Image

Cut: Use the cutting pliers to follow your marks and remove the plastic piece, exposing the screw for easy access.

 Image

🟢 INFO: This screw controls how hard the gears grip the filament. Standard settings are often too tight for ultra-flexible materials.

🔴 SAFETY: Modifying the plastic housing may affect the official warranty. Proceed at your own responsibility.
Step 7: Extruder Tension & Channel Enlargement

Adjust Tension: Loosen the tensioner screw 3 full turns counter-clockwise.

 Image

🟢 INFO: This adjustment prevents the gears from crushing the filament, which is the main cause of jams with flexibles.

🔵 PRO TIP: This new tension setting is 100% compatible with 1.75mm rigid filaments; you don't need to revert it later.

Enlarge the Channel: Assemble the drill bit into the printed handle provided in the kit.

 Image

Insert & Rotate: Insert the tool vertically from the bottom of the extruder (where the nozzle was).

 Image

Precision Turn: Rotate gently without too much force.Repeat this operation. turn twice or 3 times, then reverse slightly to clear any debris and repeat until you reach and touch the gears.

 Image

The Limit: Stop immediately when you feel the tool touch the extruder gears (metallic feeling).

 Image

🟢 INFO: This modification provides the necessary clearance for 2.20mm filament while maintaining precision for 1.75mm materials.
Step 8: Move Fan to New 2.20 Hotend

Open your new Recreus 2.20 Hotend.

 Image

Remove the fan screws from the original hotend and transfer the fan to the new 2.20 unit in the exact same position.

 Image

🟢 INFO: Your Recreus hotend is already pre-wired with the thermistor and heater cartridge for a true Plug & Play experience.
Step 9: Reassemble

Install the new Recreus 2.20 hotend using the original screws you saved in Step 5.

 Image

Reconnect the thermistor and heater cartridge sensors into their original positions on the board.

 Image

Reconnect the front cover fan plug.

 Image

Snap the magnetic front cover back into place.

 Image
Step 10: PTFE Tube

Insert a short length of PTFE tube into the top entry of the extruder.

 Image

Feed the flexible filament through the tube until it reaches the gears.

 Image
Step 11: Load & Purge (Manual Process)

🟢 INFO: For ultra-flexible materials, we recommend a manual loading process for better control.

Manually push the filament into the extruder until you feel resistance.

 Image

Using the printer's control menu, set the nozzle temperature to 250°C.

 Image

Press the "Extrude" button (down arrow) on the screen to begin the purge.

 Image Image

🔵 PRO TIP: If the purged material flows in a steady, continuous thread, your installation is 90% successful!.
