Manneken Peace - 22/03/2016

In remembrance of the terrorist attacks of 22/03/2016 in Brussels, the capital of my country.

Inspired by the drawing from '(c) kos' (http://goo.gl/3k814r). The silhouette in the picture is Manneken Pis (https://en.wikipedia.org/wiki/Manneken_Pis)

This is also my first multi color print, based on the easy color printing method from Jozef Prusa (http://goo.gl/cgqwPY).

I first sliced the STL file with slic3r and saved the GCode file (layer height 0.2mm). Then I added a M600 command just before G1 Z1.000 and one just before G1 Z1.600. Start with the Red filament for the first layers, then change the filament to yellow when the printer stops at the first M600 command. Change to black the second time the printer stops a the M600 command.

I had to enable the M600 support in the Marlin firmware by uncommenting the "#define FILAMENTCHANGEENABLE" line in Configuration_adv.h. I used Marlin v1.1.0-RC3. The code just barely works. (Jozef Prusa has totaly rewritten the M600 command support in his firmware, so I need to take a look at it).
