Well,
I'm not exactly wanting to do "DUAL" extruder prints at this time.....

Just EITHER the left OR the right.....with black filament on the Right and White filament on the left.

So I was thinking I could print any given item in EITHER black OR white depending on which nozzle I tell the build to use.

I have a feeling this is VERY easy to do and works well......I just need confirmation
