I just got the announcement for the Palette+ and its availability for use with Robo R2. Does anyone have any experience with the Palette? or Palette+ ? Or other multi-color options? I am new to this and I've had my printer about 1 month (as of November 11, 2017), and I've been making tons of stuff. I have heard about the ability to add a 2nd extruder to the R2 and I was planning to get in on that once it became available. Then today, I saw the announcement from Robo about the Palette+, and now I want THAT !!!
