[GrizHFMinimill] Re: Question about my "smart" power feed project

This sounds interesting and you're so far along your way that I doubt you'd be willing to take a turn. I'm wondering if some simpler solution using a limit switch with a movable stop might satisfy your needs. A real home return is incredibly valuable so I'm sure you've got grander ideas in store for your project than just the "stop here" feature.
