Can't change Z axis in setup

In the setup of the beginning when it asks for thickness of wood I put in .125. So when I hit enter it says something in the job is set to go deeper but there is not! I set the 3 different axis correctly at the top of the screen but it continues to tell me I have something too deep.

                 Can somebody please help me,          Thank You
