Admin edit: On page 4 of this thread, @KenO has posted instructions on how to get the Palette working on the R2 printer. Mosaic Manufacturing announced their new multi color/material palette earlier this week. The Palette 2 and the Palette 2 pro. Supposedly the Pro version will print up to 20% faster than the Palette 2 model. They also released a Canvas hub (that to my knowledge we don't need with the robo line of printers). The Canvas hub allows the printer and palette to ping each other constantly resulting (allegedly) in better communication between the two devices and more efficient printing. This looks like a really sharp device and looks like they have taken things up several notches here. It's currently available for pre-order. Palette 2 for $499 and Palette 2 Pro for $699. https://www.mosaicmfg.com/products Detail review/explanation here: I'm very seriously considering picking up one of these while its on preorder. Shipping expected in October.
