MMU Loader Test

Before a MMU print, I want to be sure that the filament will load correctly, that the first layer is doing fine and the temperatur for the filament change is also ok. 

I want to try this with this print (first print just running now ;-)).

I set the wiping options to wipe in the model, but this haven't worked out, as the whole model was then just printed in one color. Maybe somebody knows why?

I've uploaded the OpenSCAD Files for customizing, the MF3 Files for the settings, GCode and the STL files, so there should be everything needed there.

Maybe the separate fields are a bit big for testing, but this should be easily customizable.

If there is a better way of doing so, please give me a feedback, as I'm doing my first steps with MMU, I'll take every feedback there is :-)
