Extremely confused - Nonworking limit switches

This is my second linuxcnc machine I am in the process of building (First one was a C axis lathe). This is a very simple 3 axis mill and I am running into some sort of issue with the limit switches that I cannot for the life of my figure out.

Here are the facts

1. Wiring is all the same as my first machine, using a mesa 7i96s (same as prev machine as well)
2. I set my input 0 as my X min limit (although have tried home/min, max, home/max) have also tried inverted and non-inverted
3. When I get to my X motor test/tune page, I go to my halmeter and I PROBE GPIO-000 AND input-00 BOTH of them correctly change states when I press the limit switch, indicating it seems to be working correctly.
4. HOWEVER, when I open the actual machine program (am using gmocappy) the limit switch no longer works / does not change state - neither gpio-000 nor input-00 change state. If it is inverted in pncconf it will show the switch as always active and thus I cant turn on the machine, and if it is non-inverted, the limit switch simply does nothing.

I am utterly confused, it is the same code as the other machine, I must be doing something stupid but I am not seeing what that is. I will upload my hal/ini, can someone please help? Like I said I have tried setting it as all sorts of limits and homing and whatnot, and have tried inverted / non-inverted.

I am so so confused....


edit: just as an FYI - the actual axis motors move correctly, so I don't think its something like the mesa is not being communicated with in the real instance of the software
edit2: could it have something to do with the fact that i am using the same computer for both machines? (I unplug one mesa board and plug in the other when i want to run the 2nd machine)
 

Sorry, there are no pins connected to the Mesa IOs.

Yes there is a pin, it is way up in his hal file

I'm sorry, I missed it

No worries, we all miss things and mess up.
Thank you for helping.

I think my original reply did not save - these did not work unfortunately

I remade from scratch a pncconf with axis gui. again in pncconf I am seeing the GPIO-000 pin and input-00 correctly change state when i press the limit switch. Similarly I see on the board the LED light of input-00 change state

However, when I run the actual axis instance, and use hal meter to view gpio.000 or input-00 neither change state anymore, HOWEVER, the led light on the board continues to change states correctly.

I am at an utter loss. It almost seems like the input side of mesa is not communicating when I am running the software, but I do not understand how that is possible. Do you have any other thoughts? I am at a complete loss

EDIT: I have an important clue I discovered: If I open my first machine's instance of linuxcnc, and go into hal config, then I am able to see my limit switch activate successfully. I believe this means there is some issue with having two of my mesa's on this computer even though I only have one plugged in at a time. Has anyone encountered this and know of a fix? I will purchase a new computer most likely regardless but I am still hoping to figure this out while I wait.

EDIT2: I am trying to change the ip address of this second mesa to 10.10.10.11 ( I have w4 and w5 set to eeprom). It says it changed successfully, but when I try to readhmid it says no board found, and I can no longer communicate with the board. So trying to fix this now... (when I do ping 10.10.10.11 it does ping successfully)

Edit3: I have successfully changed the IP address to 10.10.10.11 and connected it back to my computer and it STILL only works in pncconf but NOT when i run my linuxcnc!!!!!
