Looks like your z-steps / scaling is off. What printer are you using?

Follow the reprap calibration guide to fix - the specific section you want is near the bottom of the page. It may require modification to your printer's firmware.

If this makes no sense or you need more info, please post here with your printer model.

Did you start by printing a 20mm calibration block to see if your X and Y axis were set correctly? It would also help you see if you were extruding the correct volume of plastic.

Looking at it I would say that you need to calibrate your firmware.
