Just bought Simplify 3D after Maker Faire Detroit and so far I'm loving it. One issue that I can't seem to work around is any time I change my layer height to 0.1mm the infill because crazy and the models loose features.
Attached are a working and non working gcode file, one with 0.25 layer height and one with 0.10 layer height. If you look at both of them the problem should be clear. In one you have a screw, the other turns out like some weird spring thing. I also attached my broken printer settings
0.1mm layer height ignores features

Re: 0.1mm layer height ignores features
One thing to look for when printing at .1 mm layer height is the auto extrusion width.
With this software they have made printing at the correct size a priority. Because of that if a feature is smaller than the extrusion width it will be ignored.
If you are using 1.75 mm filament and you print at .25mm layer height the auto extrusion will be .39 mm. So any feature that is larger than .39 mm will print. When you drop to .1mm layer height the auto extrusion width will change to .96 so you will loose any features that are smaller than .96mm .
The work around for this is to turn down the extrusion multiplier to a lower setting. Like .5 . then print a test cube with 1 shell no top and no fill.
Measure what the thickness of the wall of the part you just printed is. Uncheck auto extrusion width and type in your new number. You can play with this procedure to get exactly what thickness you need.
