XYZ Axis Problem with Mini Fabrikator by Turnigy

I recently received a Fabrikator Mini 3D printer and I have loved it; however, the last time I used it, the printer's extruder didn't go down far enough to print, thus causing the model to print out as a large plastic ball. I followed the user guide, so this issue doesn't make much sense. Does anybody know what might be causing the issue???
