Unresolved Z axis is elevated.

Whenever i click the home button, the printer homes elevated. Each time i click the home button it goes up evem more. I can see the z axis button on the right side is not being pressed. But the left side is. Any help to fix this? Also i lost my copy of the custom mattercontrol the came on the micro usb. Can anyone link me to the custom copy. Im using the vanilla mattercontrol.

 

The left side is still elevated. The right and middle side is normal. Its as if the left nut is higher than the right nut. So when the head goes on the left side the button is released causing it to think that it is touching the glass. But when it get to the middle the x arm is more heavy on the right side because of the printer head position. So the problem is is the nut on the right side being too low?

 

I fixed it. I just clicked Z- until the the nuts reached the bottom and clicked Z+ so they are back to normal.
