Homing: Was working, then "just stopped"

[AK_Eric]

I never did, looks like it was maybe a bad Arduino. I have another thread here on which Arduino / firmware to use:

If I replace my Arduino, which version of grbl to use?

I’ve had an issue with a clone board. It was an ATMega, but IIRC it had slightly less memory than advertised, and GRBL needs almost all of it. I only get genuine Arduino’s now, preferably an SMD, but if I need one today, I’ll take an IC.

Haven’t gotten around to it yet though, since in general homing switches aren’t needed.
