I'm trying to print the Elvis skull, but at .5 size... When I change the Z ratio, it doesn't seem to appropriately change the flowrate or carved layers, so the print head ends up contacting the extruded plastic. If I print something at x1.50 (including the z) the extrusion is wavy because it's dropping too far. If I leave the z at x1, I end up with a really tall skinny skull. Is there a way to get Skenforge to scale the STL before carving (or make it so the z isn't a problem)?
