Repetier Software | The software driving your 3d printer. Interesting, this is software that combines all the steps of printing in one interface and is said to be significantly faster than pronterface. There is also a Mac version, so it might be worth a try. It also comes with its own firmware, so I naturally need to find out first whether the Robo3D can work with it (but since it is based on open source printers in principle, this could very well work - and their FAQ already states that they want to use Repetier-Host directly, so the chances are good).
