I've moved on from Simplify3D. After years of using it (and paying for updates) I've reached the point where they just move too slow for me. Much as I like the interface (I still think it's the best slicer UI available on Mac), just can't justify continuing with them when they don't support several of the printers I run, they lack features (cmon - *still* no tree supports or surface additions?), and there's no way to extend it (after all these years, still no plugins?). Its a real disappointment this software has so much unfulfilled promise.
