That reminds me I've been meaning to offer a contribution to your farming robot!
For ease of interoperability, I'd like to build a one way automation that occasionally exports your OnShape design into your GitHub. That makes it easy for users to throw parts into a CAM editor or slicer, without having any on-shape experience.
Have you thought about the automation, and would you like to discuss your concerns, needs, and like-to-haves?
