In reply to DrBoost :
Yep, it's pretty rare the multicolor is helpful for productive things (although nice for making gifts without having to change spools). I like the AMS system with Bambu to keep multiple filament types ready. I even printed the same item by object this morning in 2 different filaments, both black, to decide which I would prefer before making the batch.
I will say, for GRM I far prefer Prusa or homebrew. Bambu is great for off the shelf just working but I have major issues with the software and connectivity needs.

Doesn't a multi-color head also allow you to use a soluble support filament?
I've tried solubles. They work so-so. The real deal is that some filaments won't bond together, like PETG and PLA. They simply won't stick to each other. So if you're printing PLA use PETG as the supports with a zero interface. Perfect surface finish, and the parts come right off.
With the Bambu, each switch from Filament 1->2 takes several minutes. If you have a part with an angled or curved surface you need to support it will drive a E36 M3load of filament changes and make the build take forever. (IDEX or similar designs eliminate this issue)
I really liked PLA w/ PETG support at first, but quickly decided that A) if the supported area is flat, you can tune PLA->PLA supports really damn well. B) if its angled or curved its too time consuming to be worth it, so I just use PLA->PLA most of the time anyway.
The true commercial grade solubles aren't bad, but I haven't messed with consumer grade stuff. The solubles interest me because they enable hollow parts.
