jtbarclay said that the same software that generates g-code for the MakerBot can generate g-code for subtractive machining by changing a configuration setting somewhere.
I think the cupcake g-code shouldn't be hard to make, but I haven't tried. As to formats, that depends, I have two pieces of Vectric Software Cut2D and Cut3D.
I use Turbo Cad on my Mac to make dxf files for (in 2D) for Cut2D I think vector files may be supported too. For Cut3D you can use 3D models. I'd have to check on the formats, but a couple kinds of 3D mesh formats are supported.
Check out Vectric..com they have great overviews on each package.
I've also used CamBam which has a very handy Sketchup plugin. I have a trial of CamBam, it has a funky user interface, but works pretty well, it's handy if Sketchup is how you design.
Other tools that are handy are in the control software themselves. I.e. the machine control and g-code interpreter software. I use EMC2 (Linux opensource) and it has a raster to g-code plugin. It produces a STL file basically a 3D mesh, it's nice to take a picture and carve it.
Also Mach3 which is windows CNC control software has a ton of "wrappers" that people have written, some free, some for $. I guy in a forum I use wrote one for dovetails and box joints. Mach3 can be run in a "no machine" mode for free, so I have that setup and have played with the dovetail wrapper. It's made the g-code for some dovetails, and can be exported, I just haven't cut it yet.
If you, or anybody interested is around tonight, (Weds the 11th) I'll be at the meeting and have VM's with all these tools on my laptop. I can show them to you and if anyone wants g-code created, I'd be happy to help out.
