5. Click on Next.
> FmNT checks the fiducial location by offsetting the camera in all four
directions along the X and Y axis, and relocating the fiducial. This ensures that
the number of pixels moved within the video display window is properly
calibrated to the number of mils the X and Y motors must move to find the
same location in the dispensing area.
> When this process is complete, an X,Y value is displayed in the Instructions
area at the top of the Teach Window. The X and Y values should be relatively
equal. If you notice a large difference between these two values, you should
perform the calibration procedure again and re-teach a new fiducial.
6. Click on Done to accept the results.
> The Teach Window closes and you return to the Vision Parameters dialog box.

> As well as being helpful for defining fiducials, reticles can also be used during
programming to keep the needle close enough to the part for effective
dispensing, but far enough away to prevent part chipping. See Chip Offset in
Chapter 9 Advanced Programming for more information.
