I put my first A1 Mini Combo into operation today and everything is going really well. Even continuing to print after the filament roll was empty worked well.
Unfortunately, the filament spool falls off the top two holders. A full roll of Bambu Basic PLA fell to the floor. Fortunately, it didn’t break and I was able to simply hang it back up, but of course this shouldn’t necessarily happen more often.
Are there any tips on how to prevent this? Perhaps a pressure that I can put on the spool holders to hold the spools in place?
Can you provide a pic of your setup? I also have an AMS lite and Bambu spools fit perfectly. Can you also compare the spool holders that drop the spools to the ones that don’t? See if you can notice and difference in tension or maybe a missing spring or something?
Make sure you push the spools very firmly until they click into place. If they do not “click” then do as @Leonilian said and check to see if that holder is missing a piece. My Bambu spools fit perfectly, other brands may need adapters to work.
This actually just happened to me. Brand new Bambu Labs spool of filament and it fell off the AMS. Although I was suspicious of this spool because when I was initiating a new print, the printer told me that the filament was already stuck, and I noticed that the spool was wound very tightly and the filament strand was coming from somewhere deeper into the roll as opposed to on top. After it fell, I noticed there was a crimp in the strand of filament, almost as if as it was being fed into the AMS, it the strand rotated itself or something. Kinda hard to describe.
