E stop only works when active high is set, which is wrong!

Yea, the estop has nc marked on it. If I adjust to the mach3 settings to low active it just says e stop requested even though the led for estop only lights up when the estop is pressed. I haven't got a clue what's going on.

Thats what it should do.? The LED should only come on when E-stop is pushed in. It's informing you that an E-stop occured.
When you release the E-stop button the LED goes OFF and Mach will then allow Reset.

NC means the Circuit is closed before the E-stop is pushed. So when pushed the Input you used for E-stop is pulled Low or high and that's why you use Active Low or high mach knows when that input goes Low or high and E-stop is active. The LED comes on to inform you.
This does depend on your BOB Input some are Pulled High or Low with pull up/down resistors in which case you just change the active state to match.

Don't trust the markings test it.! . . . When released you should get continuity between terminals if it's NC. When pushed there should be none.
