Endstop Problem, Duet 3 Mini 5+

[moonman]

Hi, So when i have all 3 or 2 endstops plugged in they will not trigger, if i just plug in one it will trigger but it triggers 2 inputs. That is what i think is going on. i have add screen shot of the endstop plugin with only 1 endstop plugged in and it is plugged into io3 .
this is under USB power only.
using makerbot Endstops.
I believe have the endstops wired correctly.

The first picture is of the end stop not triggered and the 2nd picture is when i trigger it.

Fixed, i had ground and signal wires mixed up.
