When should I change a rotary tip?

When it stops cutting and starts rubbing. A loaded abrasive generates heat instead of removing material, and that heat goes into the part you are working on.

Where should it sit on the bench?

Close to the work. Extraction and cooling both fall off sharply with distance, and a unit parked at the back of the bench is mostly decorative.
