We recommend that you watch the video first before unboxing to ensure the operations are correct.
Slight differences may be found between your printer and the one shown in the unboxing video in terms of protective films, foams, and cardboard.
The screen is covered with one or two protective films to prevent contamination during production and transportation. For two protective films, there will be a tear on the first film for you to tear it off. If there is only one protective film, there will be no tear. Either of these two situations is normal for a new printer.
If your printer screen has two protective films, you can tear off the first one. If there is only one film, you can decide whether to keep it or not. However, we recommend that you keep the one film to avoid scratches during use.
¶ Important Reminder:
The Y-axis of the A1 mini utilizes full-metal guide wheels, ensuring that users do not need to frequently adjust the motion components of the A1 mini. However, regular lubrication and cleaning are required to reduce wear and noise, maintain printer accuracy and lifespan, and effectively prevent rusting of the guide rails.
Each printer receives a certain level of lubrication before leaving the factory. However, only a small amount of lubricating oil is applied to the printer to avoid excessive oil that may drip onto the casing during transportation, causing noticeable stains and affecting the appearance.
Therefore, we strongly recommend applying an appropriate amount of lubricating oil to the Y-axis guide rails of your printer upon unboxing, ensuring that the entire rail is lubricated.
The lubricating oil is included in the accessory box. Please refer to the accompanying video for instructions on how to apply the lubricant:

¶ Steps to unbox and take out the A1 mini, AMS lite, and their accessories
The protective foam may vary from the machine shown in the unboxing video. Please refer to the machine you have received for accurate information. For example, some machines may have protective foam installed beneath the heatbed, which needs to be removed during the unboxing process. Early boxes include Bambu Filament Swatches when unboxing, while the latest packaging does not include Bambu Filament Swatches in the box.
The screen surface is covered with one or two layers of protective film, the purpose of which is to prevent contamination during production and transportation. Regardless of the state you receive, it is a normal new printer.
Some printers are manufactured with two layers of protective film (the first layer has a tear-off position), while others have only one layer (if you don't see a tear-off position, it means there is only one layer). Both situations will be shipped simultaneously, and you should refer to the actual machine you receive.
If your printer screen has two film layers, you can peel off the outer layer. If there is only one layer, you can decide whether to peel off this layer or not, you can peel it or not. However, we recommend that you keep the last one so that you can avoid scratches when using the screen.
¶ 1. Remove the protective cardboard from the top
Some accessories may be embedded in the foam, so please check them carefully. Please take out the components one by one and avoid removing the plastic packaging bags from the box all at once.

¶ Steps to unlock the Z-axis limiter and tool head.
¶ 1. Remove the 4 screws to unlock the Z-axis limiter that is used to protect the printer during transportation.
 |
 |
¶ 2. Cut the zip-tie wrapped around the tool head.
 |
 |
¶ 3. Move the tool head slightly to the left and then remove the foam padding.
¶ Tighten the heatbed screws.
Tighten the three screws circled in green to lock the heatbed. We suggest you move the heatbed slightly to a convenient position to use an Allen key.
These three screws are intentionally loosened during the factory assembly process to avoid damage to components during transportation. Therefore, at this step, you need to tighten them.

¶ Install the purge wiper
Slide in the Purge Wiper unit into the slot at the end of the X-Axis from the back to the front. Install the 1*M3-12 screw (for purge wiper) from the accessory box to fix the Purge Wiper in place.
 |

 |
 |
Note: After installing the purge wiper, it should be parallel to and not collide with the left edge of the heatbed, as shown in the picture below:
¶ Steps to install the spool holder
¶ 1. Install the spool holder base plate with the 2*M3-8 screws (for spool holder) from the accessory box. Please pay attention to the installation orientation.
If you want to print with AMS lite, this step would be optional.

 |
¶ 2. Slide the spool holder into place from the top to the bottom.
Ensure that the orientation of the spool holder matches the direction of the slot.
 |
 |
¶ Remove the protective films on the camera and screen

The screen is covered with one or two protective films to prevent contamination during production and transportation. For two protective films, there will be a tear on the first film for you to tear it off. If there is only one protective film, there will be no tear. Either of these two situations is normal for a new printer. |
¶ Steps to assemble the AMS lite
¶ 1. Put the AMS lite body on the stand (cable towards the back side of the AMS).
 |
 |
¶ 2. Secure the AMS lite with the 4*BT3-8 screws (for AMS stand) from the accessory box
 |
 |
¶ 3. Slide the rotary spool holders all the way in. Be careful to match colors to avoid damaging any parts (as shown in the diagram, yellow matches with yellow, green matches with green).
 |
 |
The yellow rotary spool holders have a hexagonal clip inside, making aligning with the locking position relatively easier. The green rotary spool holders have a rectangular shape, so it is recommended to align them with the hole before insertion roughly, then move them parallelly with slight adjustments to ensure alignment with the locking position.
 |
 |
¶ 4. Place the AMS lite on the right side of the A1 mini printer after successfully installing the rotary spool holders.
¶ 5. Install PTFE tubes
As the pictures show, insert the 580 mm PTFE tubes into feeder coupler connectors 1 and 2. Insert the other end of the PTFE tube from port 1 into the left-rear side of the filament hub, and insert the other end of the PTFE tube from port 2 into the left-front side of the filament hub. (Viewed from the front to the back)

¶ Install the cable organizer
Install the organizer as shown in the diagram. Clip the black cable into the smaller hole and secure the PTFE tubes into the other four larger holes. Please note that the cable organizer should be positioned close to the end of the tool head instead of the AMS lite.
 |
 |
 |
 |
The recommended distance between A1 mini and AMS lite is 50 mm, as shown in the diagram.
 |
 |
¶ Power on the printer and the AMS lite
Plug the AMS lite 4-pin connector into the port on the A1 mini. (either one)； Ensure that the 4-pin cable is inserted correctly and aligned with the direction of the protection clip.
