Generating machine code
For beginners you should try out the new Software "Slic3r".
At the moment (Version 0.5) this has a few bugs and fails on broken STL files.
We are using it for all our parts now and are really satisfied with the results.
Download for Linux, Mac, Windows: http://slic3r.org/
Previously we recommend SFACT for generating G-Code.
This is a Skeinforge fork with more sane default settings.
