Ok well this shows it's using Limit C for both probe and limit which is pin13. But like Gerry says because you tried it on another input that works then you have wiring fault. (provided you changed the Probe to same number as limit you tried)

To be honest I'm not 100% sure that link is the same controller you have because it says uses a second breakout board and i don't see one in your box unless it's hidden.? I see a ribbon cable disappearing away underneath the base plate where's that going.?
