I have an original x-carve, and the z-probe has worked fine for a long time. I think I was running grbl 0.9, but don’t know for sure. The arduino died, so I replaced it and flashed, of course I used the latest.
Now the z-probe doesn’t work at all, the machine inspector machine shows it always as “in contact” no matter what I do, I’ve checked for proper connection and shorts. Again, this worked on the old arduino with the older grbl.
I see a lot of references to grbl 1.0c having changed something, and that pin A5 (where my probe is connected) only being available in grbl 0.9, but the 1.1 grbl pinout still shows A5 for probing.
I suspect that I’ll have to change the grbl config and rebuild/flash it, but I have been looking for quite awhile now and can’t find any clear or definitive answers as to what has to change.
I see people that say they have it working with the arduino, but no answers.
I’d like to upgrade to an x-controller for the extra motor driver alone, and that would solve this issue too, but given that I haven’t used it in the last couple of years, it seems silly to throw $320 at it just to fix the z-probe.
