selecting TEST 1 or 2, and then look at the corners of the inner triangle. If the corners are rounded,
the OFFSET setting is too low. Conversely, if the corners are too pointed, the OFFSET setting is too
high.

few traces of the cutter blade, either the FORCE setting is too low or the cutter blade's tip is not
sufficiently extended.
