Two posts up from your post is this solution.

How to change the order of AMS units

So I found out the process of how to do this. Connect the AMS you want to be first to the printer hub directly, then connect AMS 2 to the AMS 1. After that go to the filament screen on your printer and tap the little settings icon, it is next to the guide button. Then click reset AMS connections and done. restart your printer and the order will be what you set it to be.

Also in this thread is a wiki to explain how to properly install your AMS.

This is a P1S. There is no “Reset AMS connections” button. This is from BS:

@Barryg41 Except all those pretty images are for the X1C not the P1S. I don’t have a P1S to check but the console images Wiki provides only has a “Reset Printer” with no explanation of multiple AMS units. Does that reset turn the printer into a log or does it only reset the AMS units?

Connect AMS to P1 series

@beatle Is the AMS button show on your console as shown in the first picture of the link above? Press that and see if there’s new options not shown in Wiki. That’s my best guess here.

On the P1x (firmware 1.05.02.00) the reset Id is available via display menu:

You can find it in the settings where you can control the temperatures, fans, light and now AMS.

Great, thank you! I don’t think I ever noticed a little down arrow on the second screen. I reset the AMS and reconnected the units in the order in which I want them to appear and it worked.

This should really be added to the instructions in the wiki.

Man I’m so sorry. I completely glossed over the P1 mention in your post.

Thanks to @print.in.3d ! It looks like you got your problem fixed.
Thanks to @Ken-N-Texas for letting me know also.

No worries, I’m not free to point a finger since I glossed over that arrow in the second menu. I am just glad the solution is there. I hope today’s posts help someone as I had searched but not found the answer.

I found it on the wiki page for Tips AMS ID assignment. Unplug all AMS’s hit the settings in filament on the touch screen and reset AMS info and then plug your first one that you want to be A1 and so forth. PS you shouldn’t have to redo the filament that’s in each AMS. I didn’t so who knows

I had same Issue with my three AMS. The last added became A the first B and last C.
In Bambu WiKi I found that you need to reset the AMS ID’s on the panel of the printer. All must be connected while resetting.

1. After the reset turn off the printer.
2. Connect the AMS1 only and turn on the printer
3. Let the printer begin to register the AMS1 (A)
4. Add the second AMS while printer is on and it will be registred as B
5. Continue to add the next into AMS B and so on.
   Now you have your AMS’s in the order you want.

Thanks Ken, your process solved my problem. In my version of firmware (May 2025) the description above the reset button tells you to do things differently which doesn’t work. Anyone having the same issue you should follow Ken-N-Texas’ procedure above
