Corners
In swivel blade technology, the knife tip is always slightly behind the center of
the tool holder and the knife offset is the distance between the knife center and
the knife tip. Adjusting the amount of corner rounding in the firmware tells the
plotter to compensate for this distance. It ensures that the knife is cutting the
center line of the shape and that the corners will be precise angles. An inaccurate
corner rounding adjustment will cause poor cutting quality and difficult
weeding.
The enVision plotter firmware provides a corner rounding adjustment feature
(corners) to help you ensure accurate corner cutting. To determine what corners
adjustment to make, cut a 1/2" (12 mm) test square. Examine the corners
(possibly with a magnifying glass) and compare them to the diagrams below. If
you determine that a corners adjustment is necessary, you can make the
adjustment in GA or follow the procedure on the next page if you are not using
GRAPHIX ADVANTAGE rules. After you have made the adjustment, cut
another test square and check it again. Continue to adjust and test until you have
precise corners.
The corners adjustment in the example at the
left is too large. In this case, what should be
a square corner is not well formed because
the plotter cuts too far beyond the corner.
