Pauses are build into the Gcode for swapping without AMS. Will make it available for AMS when my AMS gets here.

Swap Instructions:
Start with Black
At layer #9 (0.8mm) swap to Blue
At layer #10 (0.88mm) swap to Red
At layer #12 (1.04mm) swap to Yellow
At layer #13 (1.12mm) swap to White for the rest.
