Chroma is the desktop companion software for all Palettes (1.0, +, 2, 2 (S) (Pro)). It accepts GCode files from Simplify3D, Cura, Kisslicer, and Slic3r. Chroma parses multi-tool GCode files to calculate how much of each filament is needed on each layer. After processing the GCode file, Chroma produces two files: (1) a SEEM file for Palette which provides instructions on filament length production, and (2) a modified GCode file which includes color transitioning and a series of commands for pinging (which are checkpoints throughout the print).
CANVAS is the cloud platform. It accepts STL files in order to produce a SEEM file for Palette and a modified GCode file for your printer. CANVAS can save projects (prints) to be modified or printed again later.
