Adjust the V-Groove Backups and Overcuts to control specifically where the blade plunges in and retracts from the matboard or the fallout when cutting a V-Groove. 

The inside of the V-Groove cuts first in a clockwise direction. These are internal cuts, which cut into the V-Groove fallout.

The outside of the V-Groove cuts second in a counter-clockwise direction. These are external cuts, which cut into the matboard.

Make sure to select the desired Cartridge Tab, then select the V-Groove Configuration from the Current Bevel Type dropdown control before making adjustments.
