Still looking forward to this.
When prototyping small parts this would be very handy to print, check, print fast and efficient.
I am not able to track the firmwareās progress.
It would be better to track it in the āBambu Lab Softwareā category.
Also, why does it turn the hotend off every time it does anything?
Off, On, Waitā¦ Off, On, Waitā¦Off, On, Waitā¦
A question regarding this feature - will this allow also to use the full bed size with AMS filament, so no exclusion zone in case of a single color print?
If I understand this correctly, to use the full print need to fold the ācollapsable stopperā and use an external filament.
With this feature does mean thereās only need to fold the collapsable stopper and use AMS as usual?
are you sure youāre on the right thread?
Yes, I think I am. Let me explain.
Bambu has an exclusion zone on the bottom left of the bed preventing using the full 256x256 bed size. This is due to the Stopper there thatās used to push the filament cutter to cut. Bambu offers a solution to fold the stopper and fix it (and some studio settings changes), but they also state that because of that AMS canāt be used, because AMS needs to cut the filament. So they force you to feed the spool externally, which is a bit of a pain.
When printing a single color print the only need for cutting filament is when filament is unloaded at the end of the print.
This is where it connects to this thread. With the feature mentioned here, the filament will not be cut at end of print, so can use the fix but continue using AMS.
Actually, since posting on this thread Iāve already done that, and printed a 243x245 using this method (removing the relevant g-code from above that unload the filament and avoids cutting the filament) which is larger than can normally fit on the bed as default.
Hope this clarifies things now.

Ahhā¦ All clear now. Tbh. I AM especially looking forward to this feature for the time savings it brings in fast protoyping of mostly small prints (lots of time to be saved hereā¦ no unloading, no loading, no purge, etc.).
For the āno unloadingā commenting out some of the lines does the trick.
Isnāt there some g-code thatās responsible for the purge?
I found relevant g-code in How to stop purging when only one colour is being used - #10 by pauldawkins
Together the two g-code changes, saved as a separate printer profile seem to provide this feature easy to access.
Yeah. Thereās ways to make it work with g codes and printer profiles.
Weāre here hoping to get this a bit more streamlined 
This will be a nice option. Especially when printing stuff after each other.
I just found this thread because I had the same thought. Please add this Option Bambulab.

Yeah, we really need this. I cannot believe this option has not been there since the launch and still is not to be seenā¦
Adding my voice to the chorus for this feature. When iterating a part design, the filament load procedure adds a significant amount of time to my work.
I would also like to see this as a selectable feature when printing. I know it can be done by editing the start and end gcode, but I would like to see a more user friendly implementation, which is a lot more inline with Bambu Labās typical experience
Yes, it should indeed be an option to keep the last used spool loaded.
You can try modifying that section of G code.
() around a line of G code will ignore that command or put a semicolon ; at the end of that line of code and it will treat it as a comment.
I need this option as well. This a waste of filament between each print if you are using one type/color and expect to continue use into the next print.
I agree this is a feature worth having. The worst it will do is add time when I do switch filaments. The device will just have to store in its memory that a filament is loaded just like it already does for a filament fed from outside the AMS
