Thinking about trying to get auto-bed-leveling happening on my bot and read a Google Groups thread (about using FSRs for auto bed leveling on delta printers) in which @Whosa_whatsis threw out the idea of just turning the spring/thumbnut bed attachment into a simple switch (circuit closed when the bed is pressed against the underside of the thumbnut, circuit open when the nozzle compresses the spring) to replace the Z end stop.

This seems like a brilliantly simple idea. Has anyone explored this yet? Especially on a Cartesian bot with a moving bed?

@nop_head used to do this with a spring loaded circle on the corner of his bed. It was for Z height adjustment though it seems like the concept is similar enough.

Wow…fucking 2007. I’m getting old.

Cool. Unless I can scare up someone that says, “I tried it and it didn’t work,” then I’m gonna be that guy (or maybe the guy that says, “yea, it works!” of course). First I have to convert my bed from four mounting points to three however (which will of course be a nice thing to have done anyway).
