Adding M600 to change filament to Gcode

[Roxy]

I have an Alunar M508. can I use the same gcode commands to do a color change?

Unknown! But multiple filament extruders are getting some traction now. We need to add a pallet command so you can define how much filament from each of the sources is going to be feed into your extruder. For starters, that will let you mix colors. If you load primary colors as filaments, in theory you can get what ever you want as an output color. (Of course it won't be that good. But it will be a lot better than doing an M600 and changing filament to get a different color)
