G29 doesnt correct level.

Hi.

I have read a few topics about this problem but none of them had a clear solution on fixing this.

So i try to print with my pruisa i3 marlin 1.1.0rc2 ramps1.4 but any print i try to start, the on the first layer on one side of the print the head is too close to the bed, and on the other side its too far.

It worked for like 3 or four prints, but it stopped working, i tried mesh bed leveling, but it resulted in nearly the same...

Try an older release of marlin. Also check if the bed is flat, not concave or warped. Also make sure the z axis has no backlash. You can find anti backlash parts on thingiverse.
