Over at the Easel beta tester's mailing list we started talking about running a shapeoko on odd hardware, and I mentioned that I run mine on Raspberry Pi. The developers (Chris B) chimed in to ask if Easel worked on Raspian. Well, after a bit of back and forth, I came up with this workflow to use Easel on Raspberry Pi.
A quick spoiler: Easel does not yet have a local sender that works on Linux, so we'll be using a separate piece of software for sending the GCode to the Shapeoko.
