Maks Surguy, who is a javascript wizard and plotter enthusiast, created a new website to share SVGs for plotting. They generally scale well, and there are a lot of great contributions already.
I can post files from sandify up there. To get gcode out of these svgs, you can open it in estlcam, but many of these are so complicated, that might be a pain. I know there is an inkscape plugin for axidraw. Maybe that can be used to create gcode.
I want to have svg import into sandify, but svgs can be so complicated, I’m not sure how to support it.
