Mach refusing to detect an E-stop input

[cropwell]

Hello! Well I didn't rewire any in but I've just done so as an experiment and they trip the stop function no problem. So that got me thinking, I'll try wiring 24v straight across the E-stop and bypassing ground and that works fine so I've got that wired as such now to trip the E-stop.

It is a good job those BoBs are cheap.
