Marlin G-Code Output for Inkscape

Notice

Now works with Inkscape >= 1.0! There is also version for older Inkscape, check releases.

I tested it with version Inkscape 0.92 with document units set to mm and it seems to work, no other configuration is tested

Please feel free to fork and improve this extension for your own needs!

This is an Inkscape extension that allows you to save your Inkscape drawings as G-Code files suitable for plotting with any Marlin based plotter.

Users who use this extension to generate G-Code for a their machine do so at their own risk.
