Project 3D Printer RepRap

Grumpy_Mike:
the software that generates the instructions from the 3D model only really works on a PC

@Grumpy_Mike, two questions out of this ...
Does "the software that generates..." mean such things as slic3r that convert 3D models into GCode or have you a wider meaning?

Does "PC" mean anything that is not a Mac, or does it just mean Windows devices?

I am asking in case I am deceiving myself about what's available - I'm using Ubuntu Linux, and the Mac OS is not a whole lot different from that (apart from the on-screen appearance).
