I just watched the above video and noticed that the 6 colour Pikachu print likely only needs 4 colours:

• Solid Colours
  • White
  • Black
  • Red
  • Yellow
• Composite Colours
  • Pink: White + Red
  • Brown: Yellow + Black, with a dash of Red

Considering that the U1 has been the most funded kickstarter I've seen, as well as the vast majority of current AMS-style printers having 4 spools, I'm getting the impression that a 4-input hotend that can blend colours well and transition fast has more... "community relevance currency?" than an 8-input hotend that allows one to forgo buying the entire rainbow's worth of filament. The most notable drawback is that I doubt an off-the-shelf nozzle exists.

I am wondering if not having something daily-driveable is causing side effects of hesitation in my other projects. You know, "Ah, I designed this cool thing in CAD but it's stuck in the virtual realm until I decide on a manufacturing solution". The U1 is affordable at an estimated £999, but that can bankroll a lot of Coaxial8or prototypes. Honestly, the real reason I'm skipping the Snapmaker is because of its build size and that the #SlimeSaver [gd0105] concept exists.
