Hello everyone!
I'm in the same boat as Anton, though hopefully he or someone has gotten further than myself. There are no instructions and I don't know if I can run this script on OS X, but I'm giving it a try. Compiling is no problem, but upon running the script, I'm definitely in a bind. As you can see, I'm not good at this, but I'm at a loss with the limited scope I have.
Please help. I'm abysmally tired of makerware's remedial ways. Were I to be printing the same x3g file day in, day out ..there'd be no problem. However, we're making constant adjustments and new designs, and are in need of a smoother pipeline (CURA!!!) for this 3D printing endeavor to be profitable, which will allow us the resources and inspiration to branch out to reprap and/or UM. This is not to say that we're not enthused. If anyone running OSX(or otherwise) has any insight to offer, I'll be glad to share the progress.
