Shapeoko: Add a Hardware E-Stop

Weirdest thing. The machine is quite amazing. The software is pretty well thought out. The build is easy. The workflow is smooth. But where’s the E-stop?

But anyway, here’s a good start; a hardware E-stop designed and implemented by tech teacher Jamie Cuyler.

What you need:

The E-stop switch we used was found on Amazon and was wired Normally Closed (N.C.) and we followed the directions that came with the switch. We found a diagram here that matched what we did:
