IR Filament sensor values are inverted?

Filament sensor is in correctly, a are magnets and ball. And it seems to work exactly right...just it reads 1 WITHOUT filament and 0 WITH filament. Any ideas would me most appreciated.

I would check the assembly and the connections again.

Statt zu klagen, dass wir nicht alles haben, was wir wollen, sollten wir lieber dankbar sein, dass wir nicht alles bekommen, was wir verdienen.

Sure, but how would those change open/closed reporting state to the firmware?

Yep...Turns out when the sensor is way too low, it actually does this. I don't know why, but it did. I raised the sensor and moved it as far away from the arm as possible and it fixed it. THere's still tweaking to do on my end...Im going to modify the little arm that moves a bit in order to better fix. The new position of the sensor needed to be so high that the top cover didn't fit on right and the sensor still messes up on occasion. But at least I was able to get it to read 0 without filament and 1 with, instead of the other way around.
