Error:Z-probe failed
Hello, I think there's a problem when Z-probe is defined on same pin than min Z end-stop.
I have Z-probe failed error from time to time when nozzle hit bed without any clue on what happened and I can't achieve Bed Height map creation. The Z motors wires are far from endstop wires, I doubt it can be caused by EMF.
Hardware used : RAMPS 1.4 on Mega2560, cartesian printer, optical endstop with electronic pullup (10k to Vcc), pullup diabled on both Z-probe and end stop in Configuration.h.
Firmware : 0.92.3
I guess the endstop code occur just before Z-probe one and conduct to a missed step so stepsRemainingAtZHit remains negative. Perhaps endstop detection could be disabled when unsing Z-probe commands.
Feel free to ask me any other details.
Regards,
Nicolas.

in Configuration.h #define Z_PROBE_PULLUP is set to 0 by default, which is disabled. I switched it to 1 and my state now toggles correctly with M119.
