ok, you wont have the issue with support if you understand how it all works. the support system in s3d is based on a grid. it looks like a piece of graph paper. the size of the squares are set by the "support pillar resolution". 2mm is a good size for an average print. what happens is when a support grid square becomes covered a certain percentage then that square is activated and a pillar is produced. if you have a fine detail part with an overhang that sticks out but doesnt cover enough of the grid to activate that square then that is when you have an issue with unsupported overhangs. you can correct this by lowering the resolution and turn on a setting called "extra inflation distance". 1mm seems to be a good middle of the road setting with this. inflation distance takes the generated support and expands it outward basically covering those areas that overhang but arent large enough to activate the pillar. hope this makes it understandable.
