Well, I hope we can get something working for this machine or whatever 3D printer comes after it.
Yeah, the code is very rough around the edges. FLTK should compile just fine from their archives: http://www.fltk.org . It comes with Xcode and VisualStudio setups (no command line required). Maybe I missed posting some code? Also, there is a fixed path to a 3ds file in the reader, which must be changed to whatever you have on your machine.
You can also send me build issues and error messages directly, and I will try to guide you through a build: mm(AT)matthiasm.com
