So decided to try and fine tune my retraction and extrusion multiplier a bit more before I print the spare extruder. Tried to use this file.

http://shop.felixprinters.com/downlo...oad=_40x10.STL

Displays fine in the 3d view of MatterControl, but when I slice it all I can manage to get is the 2 perimeter loops that make sure you have a good flow before you start the object and then part of the top curve (60 layers though). Nothing else shows up. I tried grabbing a bunch of other single wall or 0.5mm cubes from thingiverse and they're even worse. Nothing shows up in the slice view at all and it only shows 2 layers.

Any thoughts on what I'm missing?
