Read before use

Important Safety Information:

• For best results, Bambu filaments are recommended as they have been rigorously tested for compatibility, safety, and stability with the AMS HT.
• To prevent filament from getting stuck, do not print flexible filaments such as TPU with a hardness level below 95A or damp PVA with the filament inlet of the AMS HT.
• The AMS HT supports a spool width between 50 mm to 68 mm and a diameter between 197 mm to 202 mm. Plastic spools are recommended for use in the AMS HT. If filaments with cardboard spools are used, it is recommended to pair them with a spool adapter to reduce roll slipping and debris.
• To use the drying function of the AMS HT, connect the provided power cord to it.
• During the filament drying process, the AMS HT removes moisture through external air circulation via the air inlets. Ensure the air intake and vent are not blocked to maintain optimum drying efficiency.

Component Introduction

The AMS HT features several key components:

• Screen: Displays real-time humidity, temperature, and remaining drying duration.
• Locking Tab: Secures the lid.
• Driven Support Shaft: Holds the filament spool.
• Air Intake: Allows external air circulation for drying.
• Filament Outlet: Where filament exits the AMS HT.
• TPU Filament Outlet: A dedicated outlet for TPU filament.
• Air Vent: Facilitates air circulation.
• PTFE Tube Release Button: For releasing the PTFE tube.
• Bambu Bus Port 6-pin: For connecting to the printer.
• Status Indicator: Shows the operational status.
• Filament Inlet: Where filament is loaded into the AMS HT.
• Filament Release Button: For releasing filament.
• Power Port: For connecting the power cord.

Note: The AMS HT can detect if the top lid is closed. If it is not closed when starting drying, the printer screen will display a message.

Included Accessories

The following accessories are included with the AMS HT:

• Bambu Bus Cable 6-pin
• Desiccant
• PTFE Tube
• Power Cord

Connect the AMS HT to Printers

Connecting to H2 Series Printers:

1. Place the top glass cover and AMS HT on top of the printer.
2. Insert one end of the PTFE tube into the AMS HT's filament outlet and the other end into any PTFE tube coupler of the printer. Push the tube forward for about 10 cm until it stops. Verify correct insertion by checking if the PTFE tube is visible through the window next to the buffer at the front of the printer.
3. Connect the power cord to the power port of the AMS HT.
4. Connect the Bambu Bus Cable 6-pin to the printer and either 6-pin port of the AMS HT. The upper and lower PTFE tube couplers correspond to different hotends. Connecting to the upper coupler allows the right hotend to print with the AMS HT, while connecting to the lower coupler allows the left hotend to print with the AMS HT.

Connecting to X1 and P1 Series Printers:

1. Place the top glass cover and AMS HT on top of the printer.
2. Use 2 M3*21.5 screws to fix the filament buffer to the printer.
3. Insert one end of the 550 mm PTFE tube into the filament outlet of the AMS HT and the other end into the left side of the filament buffer.
4. Insert one end of the 370 mm PTFE tube into the PTFE tube coupler of the printer and the other end to the right side of the filament buffer.
5. Connect the Bambu Bus cable 6-pin to either 6-pin port of the AMS HT and the other end to the left of the filament buffer.
6. Connect the power cord to the power port of the AMS HT.
7. Connect the L-shape end of the Bambu Bus cable 4-pin to the printer and the other end to the bottom of the filament buffer.

Place the Desiccant

1. Remove the tape from the driven support shaft. Carefully slide out the shaft, ensuring the bearings on both sides remain secure.
2. Take out the desiccant from its outer plastic packaging and place it in the empty space beneath the driven support shaft.
3. Install the driven support shaft by pressing firmly on both ends to click it into place.

How to Load Filament

Power on the printer and place a spool inside the AMS HT. Insert the filament into the AMS HT. The AMS HT will pre-load it after detection. When the status indicator next to the filament inlet is on, the AMS HT is ready to print.

How to Use TPU Filament

1. If using TPU filament with a hardness level below 95A, feed it through the TPU filament outlet on the back of the top lid. Insert a PTFE tube into the TPU filament outlet and push the tube inside for about 2 cm.
2. Place a spool of TPU filament inside the AMS HT, ensuring it rotates in the indicated direction. Manually guide the filament through the PTFE tube and continue feeding it until it reaches the extruder and cannot move forward.

Note: When not using TPU, keep the TPU filament outlet closed to prevent moisture exposure.

AMS HT Drying Function

On H2 and X1 Series Printers:

1. Close the top lid and tap the humidity icon (66%) to access the drying function screen.
2. Select the filament type, set the desired drying temperature and duration, and then tap Start to initiate the process.

On P1 Series Printers:

1. Close the top lid. Select "AMS Dry" on the screen.
2. Select the AMS HT. The filament inside will rotate once to indicate the selection.
3. Select the filament type, set the drying temperature and duration, and then select Start Drying.

Regular Maintenance

The Bambu Lab AMS HT requires regular maintenance for optimal performance and longevity.

• PTFE Tube: Periodically inspect the PTFE tube for wear and tear, signs of damage, or clogs. Replace as needed to maintain smooth filament feeding.
• Pneumatic Connector: If the PTFE tube becomes loose or filament struggles to pass through the pneumatic connector, reseat or replace the connector to restore proper filament flow.
• Feeder Unit: Regularly clear residual filament dust from the feeder unit to prevent excessive resistance during filament loading or unloading.
• Heating Unit: Keep the heating unit clean, including the fan and heat sink, to ensure effective filament drying and prevent performance-impairing buildup.
• Active Support Shaft Assembly: If the assembly is misaligned or damaged, it can cause improper gear meshing. Follow provided guides from the Wiki to reinstall or replace the assembly.
• Desiccant: Desiccant packs maintain a dry environment and prevent filament from absorbing moisture. Periodically check and replace the desiccant if its effectiveness is diminished.
