kevin, is there a better first layer hight than the .35mm?

We'll have to open the question up to others that have experimented with it. The Slic3r INI files from MakerFarm had the first layer height at 0.35mm, and I just stuck with it. When I migrated to Cura/Cura Engine, I ended up configuring it to match the first layer settings I had been using in Slic3r. Simplify3D doesn't have a setting for an explicit first layer height, but it does have a percent adjustment you can apply to the first layer. I've left S3D at the default first layer height setting at 90% of my normal 0.20mm layer height.

I would imagine that within reason, slicers should be able to provide consistent first layer results across a range of first layer height/width settings by adjusting the extrusion flow and line spacing accordingly.
