Thanks to Will Adams who mostly lurks here but posts a lot on another forum!
From the site;
"This panel arose from a need to reduce the number of steps involved in generating g-code for machines that I create to reproduce drawings made on my computer using various techniques. All of the drawings get the finishing touches in Adobe Illustrator, but unfortunately, there was no way to export g-code from Illustrator. I always had to go through the added step of opening a program called Inkscape with the sole purpose of generating the g-code which my machines understand.
This solution not only solves my problem, but could help many other people as well. I hope that you find this tool as useful as I do."
The CAM software is the gcode interpreter. AI generates a SVG file which in turn is made into a gcode file.
It is no different than Inkscape generating a gcode file from a SVG file.
Not quite - CAM software in this case is the plugin or macro doing the conversion. CAM software converts a design into the machine instructions (g-code). This g-code generator does not appear to have any sort of tool offset ability, so it’s likely only useful for sending a bit exactly along the path specified, not generating pockets, or doing inside / outside cuts.
