At this time, Palette 2 isn't compatible with MatterControl and will not connect directly to this software. Palette 2 will still work with printers that are connected to MatterControl by manually loading the print files to your printer and Palette 2's SD cards. We will consider building this compatibility in the future.
If you have a Raspberry Pi with OctoPrint, we'll be releasing the CANVAS Hub plugins. We don't have a plugin for MatterControl at this time.
