Just curious what software everyone is using... I've tried the latest version of Slicer (OS X) but it seems to have some bugs causing some meshes to be damaged during processing. With RepG I cannot seem to get dual-extrusion models to line up the way I want. Makerbot Desktop seems to work okay but just wondering if anything else is out there. I know of Simplify 3D but the price is a hard pill to swallow seeing the alternatives are all free... is it really that good?
