Just ordered an Elegoo Centauri Carbon. They are planning an AMS for it, but it will not come with it. I plan to get the Chameleon working with it, if I can, I see no reason, at this time, why not. It already has a filament cutter and a place for the "poop".
It might be July before it ships, I'll keep you posted then, unless someone else has already done it.
I think it may be worth waiting for their AMS to be revealed, because it will most likely be budget friendly, be fully supported (and hopefully reliable), and will maybe have filament drying capabilities. Then again, if you like DIY projects, this is a fun thing to build, so you may choose this. If you do end up building one, you may want to look into using directly connected klipper macros using the USB port, happy hare, and a CNC Shield with klipper flashed.
There are a ton of custom MMU possibilities, like the 3MS, TradRack, and Pico MMU. I think for the price point and the MMU capabilities, the CC is a great machine for installing a custom MMU on. I am actually more interested in the regular Centauri (non-carbon) since it's only ~$240 (final price), and after building a chameleon for, could give you a cheap P1P combo (sort of). I do wonder if the BoxTurtle would work for it, since it would fit on top like an AMS, and it already has 4 filament holders/rewinders built in.
