Pen not centered

Pen not centered
My newly built Sphere O bot works but the pen is not centered in the middle of the egg. The pen is tilted about 10 degrees (60 steps) off center. I pressed the vertical arm flat to flat with the stepper motor. What do I need to do to get the pen straight vertical?

Well by moving the pen motor 60 steps seem to have corrected the problem. If this is not the correct way please let me know.

RE: Pen not centered
Could you upload a photo? I am not sure I am understanding this... :-\
Have you tried to rotate the servo┬┤s horn so the pen lays completely vertical?

These pictures show what I'm talking about. If I manually align the pen holder to vertical while the steppers are released the egg prints ok. If it is left tilted (as in the second picture the egg is printed off center. I have the "start with pen centered" checked in eggbot control, options.
