This is a inkscape plugin, generating Gcode files from Vector Paths in Inkscape.
The code originally came from Lokster and I only changed to suit my needs.
I changed the behaviour so that the calibration up front is optional.
I also changed a scaling factor, because the old one seemed to produce too small results for me.

Head over to Lokster's Webpage for a tutorial on how to use the Inkscape plugin.

Move the files contained in this directory in to .config/inkscape/extensions

Move the files contained in this directory in to %Inkscape Directory%\share\extensions
Where %Inkscape Directory% is where you installed Inkscape, e.g. "C:\Program Files\Inkscape"

The extension will then appear under Extensions-->Lokster's Tools
