The V-Groove Exterior Overcut (red arrow) is where the cut continues into the corner before retracting the blade from the matboard on the outside cut of the V-Groove.

Exterior Cuts cut into the matboard, not the fallout of the V-Groove.

Select the desired Cartridge Tab and then the V-Groove bevel type from the Current Bevel Type dropdown control before making adjustments.

The V-Groove Exterior Overcut, which is part of the outside cut of the V-Groove, is displayed on the V-Groove Configuration Map and on the associated fieldas a red arrow.

Check against the Configuration Map of the V-Groove you are cutting to determine specifically which cuts are the Exterior Overcuts.

Exterior Cuts, such as rectangles, cut into the matboard, not the fallout of the 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.

The Exterior Overcut is part of the second pass.

This is viewed from the front of the mat. If the Exterior Overcut retracts the blade too late, it makes the exterior overcut too long on the outside cut of the V-Groove.

Decrease the Exterior Overcut.

The corners will now meet up properly.
