In case you haven't found anything yet, I wrote a quick Perl export plugin for Inkscape a while back that exports G-Code. It was 75% complete when I stopped working on it. It converts SVG paths to G-Code, but needs a lot of improvement and possibly bug fixing. I remember there was an issue without output scaling that I never fixed.
Some of the settings are in the perl file. The feed and Z heights are in there, since I didn't ever need to change them. You may want to include them in the Inkscape parameters box. The plugin should appear in the effects menu as "NC Output".
I've attached a zip file of it. Check the output before running it since there may be bugs. I have not actually tested the output on my machine, since I just wrote it to test a CNC backplot program I wrote.
Put the contents of the nc_output directory in the zip file into your ~/.inkscape/extensions/ folder. |
