I wanted to come back to this thread and provide a short update. All I can say is if you just want to buy a 3D printer and start printing excellent prints, I can't imagine it being any easier than this P1S with the AMS. Maybe it's what I am coming from, but literally unbox it, push the end of the filament into the loading port for each AMS slot and it just loads and works. So far I can't say enough good things about this. Their slicer is fairly simple and if you are using their filaments it's pretty much load the print, tell it what color(s), and print. Couldn't be happier with this purchase so far. We'll see how it holds up over time.
