As a different test, you might try temporarily removing the 110v AC from the NC side of your E-Stop PB.

Disconnected estop and limit switches, disabled estop input. ran jumper as suggested. Still falsely triggered limit. Though with a 2000 debounce I did get a longer delay. In ports and pins should z++, z-- & z home be enabled? It never responds if active low is selected.
OL I tried that last night and it didnt help. I even used that switch and switched to active low. Seems like it still triggered

Sounds like its your board that is creating the noise internally or picking it up anyway. If you can attach your xml I will have a look at it just in case there are any errors there but cant think how there could be but you never know :)
Maybe try some small capacitors from 11 to gnd.

Sorry empty file was sent, not really sure how to convert it. It is too large to post. What would the capacitors do? The board was inspected by an excellent electronics repair person who is a friend. No apparent errors and it has pased all electrical tests with no issues.

The capacitors may help to  filter any noise that is present.
To attach your xml copy it from the Mach3 folder to your desktop and then rename the copy as Fastest1.xml then the forum will accept it.

Any particular value? Is it possible the capacitor can damage the board?

And how would I use it? Would each input get a cap or just attach all grounds to 1 cap? Or some other way?
