Yeah, got mine today. Looks like they gave in a little and included shells. It doesn't matter if we paid anything. What if I said I was giving away a truck equal to an Xterra if you registered at my website and then gave you a crappy truck that you couldn't drive anywhere. Can't export 3D DXF files. If I can't convert it to G-Code it's of little use to me. I'm new to CNC so maybe there's something I can do with an STL file, but I've never heard of it. I guess after I retire I'll have to write my own open source 3-D modeler that exports directly to G-Code. Doesn't seem like it should be that hard;)
