This is an independently created file, uploaded to the Eggbot code repository– I don’t think that anyone currently involved with the Eggbot project has tested this.
It should be straightforward to copy the relevant parts of the Eggbot extensions for Inkscape into separate files that you can call independently. Alternately, you might want to look at driving the EBB directly from its command set, or using RoboPaint– the latest version has experimental support for the Eggbot and an open API.
