Layers issue

My prusa i3 which I wasn't using for months prints the same layer over and over even on my repetier says the hot end is on xx layer with 5,10 or even 100mm doesn't matter is scratching the glass, the auto leveling works, I can move the extruded up and down left and right but is getting on my nerves and I need a part printed for my Kossel

Found the problem ... calibration, I had to calibrate the all thing and now is back to work.
