I have 4 different colors in my AMS. If I run out of black in slot #1 when printing an item, can I get it to continue printing with the white in slot #2. Even though the colors are different in each slot, the filament is the exact brand. I don’t care if my i or print comes out multi-colored.

No.
For Autorefill two slots have to Have the exact same Filament configured. (Type and color)
What you can do: put a spool of same Material-type into the empty Slot after runout. Color IS irrelevant.

Yes - The auto refill function will work if you manually input your “replacement” spool as the same type and colour in the AMS before you send the print. There are people who setup every spool in their AMS as “black PLA” for example so that the auto refill function will work even though the filament colours are different.

yeah it would be nice to at least be able to using the app to tell it to switch to different filament if you get the notification that it has run out. What I do is just go over to printer, and move one of the other filaments to its spot to finish print.

Hi all, Thanks for the replies. Do you think the AMS will freak if I put different Bambu Spools and change the color. I ask this as the Bambu Spools have the RFID tags so if I manually change the color, when it starts will it see that the spool is different and when it runs out won’t automatically switch over and keep printing?
Ah ha! So that’s why my print wouldn’t flip over. Thanks for the easy and clever work around. While colour is irrelevant to me, I didn’t realize it mattered to the machine even though they were all the same Bambu filament basic PLA.

yeah kind of sucks… not sure why but perhaps next update could allow to use same filament type and brand only different colour. Think it is not too hard to do …

Just a reminder for anyone reading about auto switching filament spools - Bambu’s taping method of securing filament to spools is still causing issues with pulling tape and adhesive into the AMS mechanisms and tubing.
Might want to watch an end of spool event closely with a spool that’s taped to know what’s up before relying on it to work unattended.
To be fair, Bambu’s position is they have addressed this and no need to worry, but people are still reporting issues.

We purchased our printer and a few spools just a couple of weeks ago. Loving the printer but the tape at the end of the spools is a PITA. I’m hoping this is just old stock and will quickly resolve?

I’m hoping the same. I’ve had 3 jams/AMS failures so far with tape jammed in the AMS filament feed hole. This last time I opened a support ticket and they sent me a free roll of filament as replacement. I will continue doing that at every occurrence. I’ve started getting rolls with the filament bent into a little locking L…but I’ve heard of jam problems with that method as well, I shall wait and see.
I’m new to the AMS and have two spools getting close to their ends. What is the proper way of handling the exchange of spools? Is the filament supposed to release from the spool and go into the printer and the printer will stop when there is no more filament?
Or is the end stuck to the spool and the printer will encounter a situation where it can’t pull more filament into the printer and stop?
Do I wait for an automatic stop? Do I pause it for best results?
What will happen and what am I supposed to do is basically what I’m asking 
It’s supposed to freely release from the spool from the tug of the AMS feeder and then do one of two things
Feed until the toolhead detects it has run out and stop and ask you to put a new spool in that slot of the AMS
or
Feed until the toolhead detects it has run out and automatically switch to another slot with the same filament in
It’s fairly hands off, no need to pause, just follow what it asks you to do
If it looks like it’s not going to release from the spool, I open the AMS and snip the filament free

The filament is supposed to pull free from the tape and leave the tape stuck to the hub. What happens in reality is that doesn’t always work and filament pulls the tape off the hub and into the AMS feed mechanism.
All I can tell you is what I do - keep an eye on filament remaining and be there to cut the filament free from the hub before the AMS ingests the tape.
What should happen is the AMS sees one filament run out and swap to another spool for essentially uninterrupted printing. Instead, if the tape pulls off the hub the AMS can jam as tape gets pulled into the mechanism.
I don’t pause to cut the filament free. I do it on the fly. Pauses add interruptions to the print and can leave defects if they happen on outside walls. After cutting free the printer will keep using filament in the tubing until the extruder notices and then the AMS should do whatever you have it set to - resume with another spool or continue on with a new spool you load while the printer is finishing off the previous filament.
And why Bambu still hasn’t fixed this is beyond me. It breaks a bulleted feature of the AMS they love to promote, it ruins prints, it wastes filament. The tape method is an abomination and has tripped up lots and lots of people and will continue to do so as long as taped filament remains in inventory.

Print this and all your anxiety will go away. I am currently using it and it works great.

I have a question about the ams. My fist slot broke during a long print and I had to abort it. My print is only two colors, but I’m worried that I have to re do the entire job if I change where the color that was in the first slot get moved to slot 3. I went under object and under the tab fila,. I changed it to 3 and then I just left one empty. will this work?
You should be able to move the spool to a different slot without any any issue. Just make sure that the printer (If you have an X1C) matches the slot correctly or (if you have a P series) that Bambu Studio matchs the slots/colours correctly when you send the print.
Has anyone had an error code 3030?
I’ve had it happen a few times where a spool has jammed through one reason or another. AMS lid too tight… tangled filaments, random spool my son dropped…
Is it posible to get the AMS to swap from say… slot 3 to slot 4 if slot 3 jams?
The auto change filament when empty is great, but my print last night stopped at 1am due to tangled filament and should have been finished this morning ready for the next lot to start. If I could set it to auto swap to slot 4 of the same filament as it does when the reel runs out that would be perfect.
