We all know the error messages of the AMS by now… Filament cannot be retracted… you red LED is flashing or has a steady light… and we have all tried to simply push a piece of broken filament on or back. And we all failed because something somewhere blocked the way. Who hasn’t been forced to open the AMS? Pulling off the hose, loosening the two screws, being careful not to tear off the cables… and all because of a small piece of filament somewhere in the system. Do not get me wrong. The AMS is a piece of cake compared to the MMU from Prusa and does a good job. But the troubleshooting is a tragedy on the part of Bambu. It can’t be that you have to take the part apart every time because something is in the way somewhere and prevents a filament from being pushed through. Is it not possible to program the path (e.g. in the maintenance menu of the printer) for the corresponding sensor in the event of an error message? To manually control the corresponding stroke in the AMS and the motor that feeds the filament, so that you can push a piece of filament to push the broken piece in any direction? The constant disassembly is also not conducive to the durability of the connections and at some point nothing works here because threads are worn out or something breaks off…
Maybe there is another way than the one given by Bambu for troubleshooting in the wiki? Maybe I just haven’t found it yet?
I mean here there is potential for improvement that can make life easier for all users…
Me! 
And i have lots of luck!
I have not yet needed to open the AMS (except to install the Hydra insert). Early on I did print one of the PTFE tube guides that snap onto the extruder - this makes it less likely filament will bind at the extruder. I also make sure there are no sharp bends in the AMS tubes.
I have not had to either, and I am around 20 spools through it. I have had jams, but I have been able to pull them out the back.
If you keep breaking filament, then there is a problem with your filament storage, age or brand. Should not be that brittle that you are leaving pieces behind.
Well I unmounted it tens of times but that was just to find a way to print TPU. Appart that, I had some filament that was breaking inside, I just dont use those filamanet anymore (all Geeetech PLA & PLA pro tend to break in my case), now zero issue since I have stopped to use Geeetech PLA.
One thing that would help with the AMS is to have an access panel on the bottom to easily get to the stuck filament.
Yes completly agree, it could also serve to tighten the tension spring of the output AMS extruder as for now I think it is the reason some filament break inside, too much tension
… that would be aufjeden case on the part of Bambu a consideration worth… that would be a good approach
Of course, it can have various causes the filament breaks… including storage or the manufacturer. It affects everyone at some point, whether he can do something about it or not. The point here is that there are ways to eliminate a fault in the AMS more easily and quickly… Disassembly cannot be the way! Bambu would like to collect ideas from users to improve their products? Well please, here is the opportunity to express his ideas…

Agree 100%. If the filament has broken, just feed the filament through until the broken part is extruded and keep rolling. My 8 year old flashforge creator pro let me do that. Or, another option, just disconnect the back tube that I can get to and force feed it out to there so I can remove it.
I don’t use my printer super often, but those times I do, when I have to deal with broken filament, I just want to quit using it altogether.
Same here, I agree it would be so easy to just push filament through when it’s broken instead of unmounting all of it…
I’ve not had to open my AMS in over 900 hours of print time but do support the idea of being able to manually run the motors to help clear out broken filament. Something to the effect of disconnect the tube from the back of the AMS then put it in manual. Insert filament into the affected path feeder then press and hold forward till the pieces come out the back. And have a reverse button in case it’s so stuck the above does not work. No sense getting even more filament stuck in there.
I did have to disassemble the extruder due to a TPU jam so it’s not been 100% perfect.
