Auto level for the Folger 2020 Prusa i3

I follow a number of FB groups and forums about 3D printing in general and the Folger 2020 i3 in particular and questions about auto level keep coming up.  The 2020 i3 doesn’t ship with autolevel, but when I ordered mine I thought auto level sounded like something I’d like and Folger sold an inductive sensor for just under $4 so I tossed one in with my order.

Wait, a new project already?

Yeah, I know.  I haven’t even finished blogging about the build of the 3D printer.  I do want to add more about that, but it’s proving very difficult to do more than 24 hours after I did it.  I may be doing some re-wiring on it to clean things up soon and that will make it easier to remember the gotchas I ran into.  The 3D printer has been working great for me – a few minor issues now and then but is overall really working better than I had expected.  So the past week I’ve had it busy working on parts for my next project.  I estimate I still have around 35 hours of printing (give or take 10 hours) before I can move onto the next stage of this project but here’s the start of my attempt at building a CNC machine.

An idea so perfect…

How I never thought of this I’ll never figure out.

Yeah, the amp I made sure came out clean:

But I win zero points for style when compared to this:
