Dust thank you for that input and I am using a piece of Aluminum that is about 1/8" thick I don't think that is what is going on, but thank you for the thought. Let me know if there is any other questions or things that you can think of.
I have seen in numerous places that the pullups should be disabled for Optical Switches but I have tried enabling them and there is no change
Here is a link to the endstop we are using.
[www.amazon.com]
I have plugged this endstop into a UNO just to test it and it functions properly I also check the voltage while its plugged into the Ramps and there is a noticeable voltage drop it goes from .45v to 4.7ish volts when it is triggered or not but the firmware or board is not noticing the change. I even swapped the Ramps 1.4 with another one that I ordered to fix the issue and still the same outcome.
If you'd like to see more about wiring or the unit itself go here I posted this a few days ago...

I am starting to worry that the signal pin is fried on 2 ramps boards! even though I know that is pretty unlikely. If you go to the wiki for endstops there is a troubleshooting section and it states that if the voltage changes but the board isnt noticing it that it could be the wrong pin is selected in the firmware but I have no clue how to verify this. I'll post the link to the page, I wish I had more hair to pull out lol ;) :P
