Mach3 Setting up home and limit switches

[CrazeUK]

Hey Guys.
So i decided i couldnt sleep, so spent the night trying to sort out the home and limit switches.

If i understood this right:
THere will be 4 Separate inputs to the driver board.
1. X Home (Currently not connected / Off in mach 3)
2. Y Home (Currently not connected / Off in mach 3)
3. Z Home (Currently not connected / Off in mach 3)
4. X, Y, Z in series, with an emergency Stop added in series later. All set to CLosed, until tripped. (Connected / Pin 15 mach 3 - Tested with multimeter to open circuit.)

I have found that Mach3 emerngency stops every few seconds when i have Active Set to low for pin 15.

Also in the Port 1 Pin Status lights i have the following:



When i push one of the limit switches, The marked one lights up (i presume this is telling me the pins dropped).

Any help?

Thanks
