We have typically steered away from detecting the traing edge of a hole when hole detecting. Due to possible material burs, oil and other things causing the hole detect input to bounce on the leading edge, we would detect the leading eadge instead.

We have added some additional validation to prevent that from happening. A new setting called Minimum Hole Size has been added. We have also added a setup to select which edge of the hole we are detecting. It has two settings, Leading Edge and Trailing Edge.

Whe we are trying to detect the Trailing Edge of the Hole, the Sensor input must be ON for at least the Minimum Hole Size before we will count a hole on the ON to Off transtion of the sensor. This prevents a minor blip in the sensor state from triggering a hole on the leading edge transiton of a hole.

It is assumed that the Minimum Hole Spacing setup will be larger than the Minimum Hole Size setup.
