yeah the ams is not a solution for multimaterial prints. there’s so much that can go wrong with mixing filaments in the same nozzle. i’m really happy with my snapmaker though, it can do the material switch as well if you mount two spools with the same material. the only thing i’m missing is being able to tell it “switch to this head” if there is no matching spool mounted, and getting it to notice new spools being loaded during a print.
