Please remove the buffer from the back of the printer (if applicable) and install the AMS Hub, as shown in the image below. Once the AMS Hub has been installed, proceed to connect the PTFE tube from the Hub to the PTFE coupler.
Please ensure that the PTFE tube runs under the spool holder and not over, as shown in the image below.
The spring within the Hub should not be stuck/compressed. Please ensure that it moves freely within the Hub.
Connect the Hub to the printer with the Bambu Bus 4-Pin Cable (note the orientation):
Connect the most frequently used AMS to the AMS Hub and turn on the printer, and then proceed to connect the remaining AMS to the other 6Pin port of the previous AMS.
Having the correct PTFE Tube length is important. We suggest having it as short as possible without over-bending it to reduce AMS feed resistance and load/unload time:
Now that the installation is complete, please check your printer to see if the Hub and the additional AMS units were correctly installed, please see the image below as an example of a successful setup.

Each AMS is assigned an ID, which is displayed on the screen. The logic for assigning AMS ID is to easily identify the connection between them, e.g., AMS1 is directly connected to the AMS Hub, AMS2 is connected to AMS1, and so on.
Do note that you will need to connect them individually to be able to assign the ID in order. Please ensure you keep the printer on while doing this.
However, if you connect multiple AMS units in advance and then connect to the AMS Hub at the end, or you connect all AMS to the hub before powering on the printer, it will randomly assign IDs to these AMS.
The AMS has a “mapping” function (refer to multi-color printing operation guide), so the ID of AMS will not affect the new printing, but the built-in model will be affected. Please refer to Tip 2.
The AMS ID will be saved and not cleared even if the machine is turned off. You can reset the AMS ID as shown below:
Currently, printing the built-in models only supports printing start from slot 1 of AMS1, with no support for mapping to other slots. You will need to place the filaments into the AMS slots from left to right according to the prompt on the print launch page:
