Auto cal problem

[Threephourths]

So I just got my Duet Wifi hooked up and when I auto cal it hovers above the bed, checks a few points and then gives me this error: Z probe already triggered at start of probing move.

Any ideas?

Which probe are you using? The firmware is registering the probe as triggered when it should not be.

Might be mis-confgured as falling signal M558 I1 when it should be rising signal m558 I0 (or no I switch at all).
