And besides us, there are plenty of artist machinists you could talk with about fabbing one off shapes, they're just on different lists related to emc2, small milling machines, etc. JG ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user -- http://www.coe.neu.edu/~efoss/ http://evanfoss.googlepages.com/ ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

The G code macros it will make are about cutting simple circle or rectangle shapes, then outputting a series of moves that will cut a global depth of cut setting and repeat while necessary. I did not see anything generating spline curves yet. I cannot find any import export function yet. So far, Blender --python scripts to create G codes -- GCAM setup details added to G codes -- machining job shop is the most reasonable flow I have found to make real parts with. It might be possible to go from blender -- STL --??-- IGES, but I've not found how yet. GCAM checked G codes are farther along than an IGES file, so your charges at the machine shop would be less with them. Whether GCAM would show in 3D a set of G codes that follow a spline curved surface from Blender is an interesting question to answer... ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Hey John, I spoke to a local vocational high school's drafting department who couldn't wait to get their hands on this project. I gave them the measurements of my backrest and they are running with this. It gives their students a chance to work on a real project, to help the disabled and to use the more advanced features of their software. I couldn't beat the pice since it's free! Plus this frees me up to work on the code for my temp control chip. Thanks for digging into this and if you continue to explore this I'd be interested to know what you find out.
