I really like openscad, and the uphill struggle with Freecad has just begun to get easier. I had no idea that Freecad could make g code until Todd just told me 🙂

I have struggled with the CAM portion that does the DXF to G-code, however. It does not seem well supported- email inquiries go unanswered. My two-cents.
