Layered Color Method

---

Marlin firmware supports the M600 GCODE command for filament swapping, which with a little planning can be used to achieve multicolor prints on a single extruder 3D printer.

By creating designs that separate colors by layer height, you can stack any number of colors upon the previous layers. It takes a little forethought, but the results can be rewarding. This method works great for custom signs, clocks, plaques - any two dimensional art that could use a little color.
