It should be IN #8 and yes it should be wired to your E-Stop and possibly Limit (not Home) switches. can't remember if the Limit Switches are just part of the E-Stop circuit or if they have their own circuit. You can test this quickly by manually depressing a Limit Switch, like the one on Z axis 2/3 of the way up the column. if one of the other LED's light then they are separate (this is a good thing). I think they are typically wired in series and because it is a Normaly Closed circuit, if any of the switches gets activated (OPENED) then it breaks the circuit and causes an E-STOP signal.
Step 1. Be sure that Mach3 is looking for E-Stop on Pin 8. See the image I posted above to verify.
Step 2. Disconnect the Pendent. Does this solve the issue ?
Step 3. Disconnect the wire that is currently in I8. Jump I8 to ground. If the Emergency light goes out then you can be pretty sure that it is an E-Stop Switch or the wiring to and from it. I
Step 4. Reconnect the wire in I8 and then access the back of the E-Stop switch. Visually inspect for damage or loose wires. Be sure the E-Stop switch is in the RUN position and then use a jumper to Jump across the switch. There should just be two wires going to the switch and you want to "connect" Them. If the Emergency LED goes out then you know the switch is bad.
It is interesting that you circuit board is different from mine. Where does the smaller ribbon cable got to ? I assume the larger one goes to the Pendent.
