Using Open Source and CNC?

blueZ3 asks: "I am thinking about purchasing a CNC (Computer Numerically Controlled) milling machine to build small parts to support my hobbies. I'm looking at a machine from Tormach or CNC Masters. These are small, hobby-class CNC mills. Even though I've picked low-cost machines that look interesting, they all require software that adds significantly to the cost of the machine. I've worked with proprietary CAD software before (TurboCAD, AutoCAD) so drawing parts isn't a big deal. But I'd like to avoid spending huge amounts of money on software, when I'm already breaking the bank for the mill. Does anyone out there have experience using Open Source software for CAD that has a relatively 'normal' GUI/interface? Is there a 'mature' CAM conversion software for same? Does anyone want to comment on the intersection of Open Source and CNC?"

OK, I just realized that I totally misread your question. I don't remember there being any open source software in the GPL sense, but I think there was some that would give you the source with purchase. That said, if you can't find any, you can always build your own.

I don't know of any specifically. But the only part you'd really need to make would be something to turn 3D models (which you could always make in Blender or some such) into the G-Code file to feed the machine.

Just buy the software

I don't understand why you would pay thousands (or tens of thousands) of dollars on a machine, but you won't pay a measly $400 for the software? That just doesn't make any sense. If you are going to invest that much, why worry about the cost of software?

How about worrying about your freedom?
