Mach3 Setting up home and limit switches

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:

Attachment 20564

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

Just an update,

I have now set the home switches up in Mach 3.
They seem to work fine. - Quite impressed with my self lol

I do however have a problem, the Limit switches keep triggering an emergency stop.
I have set the State ti both low and high and tried it.

Could it be faulty switches?

What type of limit switches are you using? How have you connected them, and what BOB are you using? Need a bit more info before we all start guessing!

Hey. Thanks for your response.

The current ones set up are micro switches most are the 2cm ones.. I presume because of the size of the machine it doesn't require much more.

I am tempted to replace all of them with new ones.

All (including home and limit) are set up as always closed.

I am pretty sure the wiring for the limit ones (in series) is all checked through and is in series (was a bit messy when I got it) I've have tested it with a multimeter, and the resistance drops to infinity when I hit one.

The board is a CNC4X45A. Like the one attached:

I fiddled around with the pin numbers, the home switches are 10-12. The eStop is 15.
All are set to Low active.

Thanks.
