Avoiding passes over already machined zones
Often, the machined piece will bend because of the thermo treatment and it can break when the cutter head is moved above it. In order to avoid such situations, the passes between cutting in points can be done above the unmachined zones of the sheet. When the function is turned off, the passes will be made following the shortest distance between the points. When the function is turned on, the passes are made in such a way, that the cutter head avoided passing above the already cut out contours.
