I created a document on how I use Inkscape and the included extension Gcodetools to generate gcode to operate my RugBot. This and some of my other posts may be useful for anyone needing to use syncronized tangent moves of the A-axis. Depending on what version of Inkscape you try to use it can be a real pain to try to get Gcodetools to work, but they tutorial explains some of the work arounds. If the pdf is to blurry to use I can try to zip it at a higher resolution if needed. Moderators should feel free to move this to a different topic.
I am currently between having shop space so I don't have a working system at the time. And as always, thanks to all the great help and support from all the users of this forum.
