Re: Optimizing cutting paths - The proof

Thanks John!

I've downloaded the DXF file, and I found that Vector CAD/CAM, TurboCad,
IntelliCAD and ACE don't like the file format!

I WAS able to load it into Flashcut (and generate a Gcode file), and
see/print it in my BobCad demo. Hopefully I can find a work around to
get it into Vector!

I took Flashcut's generated Gcode and imported it into Vector CAD/CAM,
but the large circles (rim) and some of the small arcs are off. I'm
going to try to figure out what is off in the arcs.

I might just walk through the Gcode and/or the DXF file and try to see
what's going on... I'd like to be able to understand what the problem is
(and fix it!).

FlashCut's Gcode must be a slightly different flavor then the iso (?)
vanilla flavor I'm accustomed to working with. Seems like the Arc's are
not relative I & J? I haven't found a control for that in FlashCut.
