Oh interesting, my AMS has worked flawlessly. This is interesting because I've tried many multimaterial solutions, and other than a Voron with multiple hot ends, none of them worked well at all until the Bambu AMS. It was really wasteful at first, but that was the only negative thing I could say about it. Maybe Bambu Labs has more QC problems than I thought. My experiences were all so simply and directly positive (across 4 of their printers now), I kind of expected that to just be the norm.
