Seen a bunch of preliminary videos on this recently in the youtube sphere.
Similar to the H2C in that it swaps nozzles. Unlike the H2C, instead of magnetic placement it uses a 12 nozzle carousel, and an eighth turn lock to lock the nozzle (and heatbreak/sink) into the carriage from underneath. This is not just screwing a nozzle in, like the H2C it is the entire hotend.
The 6 spool AMS style cabinet has active heating/drying and looks pretty slick.
While there have been no info yet on color swaps, they have a 2 stage system where the next color to load is already staged at the back of the printer. So unlike Bambu's, you don't have to wait for the filament to fully retract and then fully get pushed into the hotend. The filament retracts past the buffer and the staged filament is immediately pushed into the hotend once the first filament clears the junction.
