Bambu Lab AMS HT Quick Start Guide

Getting Started

Before using this product, please read this guide carefully.

Safety Warning: Do not power on the device before completing the installation.

The AMS HT is a smart system that requires regular maintenance to ensure optimal performance and lifespan.

Recommended Usage:

• It is recommended to use official Bambu Lab filaments. Extensive compatibility, safety, and stability tests have been conducted based on the characteristics of AMS HT to ensure the best printing results.
• To avoid filament jams, do not use AMS HT to feed flexible materials with a hardness below 95A (e.g., TPU) or damp PVA.
• AMS HT supports filament spool widths of 50mm-68mm and diameters of 197mm-202mm. Plastic filament spools are recommended. If using paper spools, it is advised to use spool adapters to reduce the risk of slippage and debris residue.
• To use the drying function of AMS HT, you must use the provided power cable for power supply.
• When drying filament, AMS HT expels moisture from the inside through external circulation. When external circulation is active, the air inlet and outlet will open. Ensure these are not obstructed by other objects to achieve optimal drying results.

• Power Cable

Connecting AMS HT to H2 Series Printers

1. Place the top glass and AMS HT on top of the printer.
2. Insert one end of the PTFE tube into the AMS HT outlet and the other end into any of the printer's inlets. Push the PTFE tube forward approximately 10 cm until it cannot be pushed further. (Observe through the window next to the buffer on the front of the printer; if the PTFE tube is visible, it is inserted correctly.)
3. Insert the power cable into the AMS HT power cable interface.
4. Connect the two ends of the 6-pin connection cable to any 6-pin interface on the printer and the AMS HT, respectively.

* The upper and lower inlets correspond to different hot ends. If the AMS HT is connected to the upper inlet, the right hot end will be used for printing. If the AMS HT is connected to the lower inlet, the left hot end will be used for printing.

Connecting AMS HT to X1 and P1 Series Printers

1. Place the top glass and AMS HT on top of the printer.
2. Secure the buffer to the printer using 2 M3*21.5 screws.
3. Insert one end of the 550 mm PTFE tube into the AMS HT outlet and the other end into the left side of the buffer.
4. Insert one end of the 370 mm PTFE tube into the printer's inlet and the other end into the right side of the buffer.
5. Connect one end of the 6-pin connection cable to any 6-pin interface on the AMS HT, and the other end to the left side of the buffer.
6. Connect the power cable to the AMS HT power cable interface.
7. Connect the L-shaped end of the 4-pin connection cable to the printer and the other end to the bottom of the buffer.

Placing the Desiccant

1. Peel off the sticker on the drive support shaft and carefully remove it to avoid dislodging the bearings on both sides.
2. Remove the desiccant from its packaging and place it in the space below the drive support shaft.
3. Reinstall the drive support shaft, pressing both ends to ensure it is securely in place.

Loading Filament into AMS HT

After powering on, place the filament into AMS HT and insert the filament into the inlet. AMS HT will automatically pre-load the filament upon detection. Once the white light next to the inlet illuminates, you can start printing.

Using TPU in AMS HT

1. If you need to use TPU with a hardness below 95A in AMS HT, you must use the TPU outlet on the back of the top cover. Insert the PTFE tube into the TPU outlet and push it approximately 2 cm into the AMS HT.
2. Place the TPU filament into AMS HT, ensuring the filament rotates in the direction shown in the diagram. Manually push the filament through the PTFE tube to the outside until it is fully inserted into the extruder and cannot be pushed further.

* When not using TPU, ensure the TPU outlet is tightly closed to prevent filament from becoming damp.

Using the Drying Function on H2 and X1 Series Printers

Close the lid. Tap the humidity icon ? to enter the drying interface. Select the filament to be dried, set the drying temperature and duration, and then tap 'Start' to initiate the drying program.

* Visit wiki.bambulab.com/zh/drying for more detailed instructions on the drying function.

Using the Drying Function on P1 Series Printers

1. Close the lid. On the screen, select 'AMS Drying'.
2. Select AMS HT. Once selected, the filament will rotate to indicate the process.
3. Choose the filament type, set the drying temperature and time, and then select 'Start Drying'.

Regular Maintenance

Bambu Lab AMS HT is an intelligent system that requires regular maintenance to ensure optimal performance and lifespan.

• PTFE Tube: Over time, the PTFE tube may wear down as filament passes through, potentially causing feeding issues or blockages. Regularly check for signs of damage and replace as needed to ensure smooth filament feeding.
• Pneumatic Connectors: If the PTFE tube connection is loose or filament cannot pass through the pneumatic connector, try reinstalling or replacing the pneumatic connector to resolve the issue.
• Inlet/Outlet Components: Regularly clean residual filament from the inlet and outlet components to reduce resistance during filament feeding and retraction.
• Drying Component: Keep the drying component clean, including the fan and heat sink, to ensure efficient filament drying and prevent dust accumulation from affecting drying performance.
• Active Support Shaft Component: If the active support shaft component is not installed securely or is significantly damaged, it may lead to poor gear meshing. If this occurs, follow the tutorial to reinstall or replace it.
• Desiccant: The desiccant helps keep the inside of AMS HT dry and protects the filament from moisture. It is recommended to check its condition regularly and replace it promptly when it is no longer effective.
