Not OP, but I chose not to go Bambu because of the closed ecosystem. I like that they’re enabling custom firmware now, but they presented as very closed and proprietary, including network printing going through their cloud. While I’m not printing anything sensitive, I could see that being a concern for some, especially if you’re designing your own prints. I get that they’re the turnkey solution that “just works” out of the box, but so do my Qidi X-Plus 3 printers, and I can SSH into them if I want.
I would love to do multicolor or multimaterial printing, but there’s no alternative to the AMS right now. I also feel like the “right way” to do this is how the Prusa XL does it, which is multiple extruders. This cuts down significantly on the amount of waste, though the quality of the AMS approach still seems to be better for now. Granted, I haven’t actually needed to print multiple colors or materials yet, so it’s not really a big deal.
