Workflow
--------
- analyze geometry, e.g., by viewing ben-bottom-inside-500um
- define CAD model in cw.py
- generate in HeeksCAD with "import cw"
- define Zig-Zag operation
- generate Python script and run it (takes a while)
- save NC file
- convert G-code to gnuplot, with cncmap/g2gp
- mount piece and determine geometry with millp
(from http://svn.openmoko.org/developers/werner/cncmap)
- define conversion in "doit" script (to do: put in repository)
- ./doit >job
- send job with cncmap/spool
