Printing multiple materials with an AMS-like system will usually cause print failures. Remnants of the materials will stick in the single print head and mix with the incompatible materials. And manually switching isn't feasible if you're trying to do something like print supports--are you going to swap filament rolls by hand every layer?

I've printed _many_ parts with multi-material using AMS: PLA, PETG, different support materials. Never had a single failure. It's wasteful, but never had issues.

No, first because I would use support material just for the interface and if it's curved, then no. Even with X1C's AMS, any IDEX, H2D print time would be hilariously ballooned. I'n saying that dual-nozzle design didn't make it possible, it made it more convenient.

That is curious. I've only tried multimaterial work with an AMS Lite on an A1, but it critically compromised layer bonding due to residue, and it was a reproducible problem.

I have a whole rc plane printed out of PLA-LW and PETG for interface, model used a lot of supports. Still in one piece. My only print issues with x1c:

- I forget which plate was used for petg and which one for pla and mix them up

- Revo nozzles had clogs, solved by switching to diamondback

- Can't pull the very end of the 3rd party spools and either gives me "motor overloaded" or void layers.

I've printed both PETG and PLA just fine (using PETG as a support interface) in the AMS. The key is to turn off the prime tower, and increase the flushing volume between those materials. (I do now have an H2D, and it's definitely an upgrade over having to do that)
