On an enclosed machine a cutout slug that tips once cut free can stand up
above the sheet and catch the enclosure door when the pallet changes. The
head already keeps off cut cutouts, so this is about clearing the door, not
the head.
Cutting Settings > Cutouts > "Slice slugs the support grid can't hold
level" (CuttingParameters.SliceTippingSlugs, off by default, saved per
machine thickness and written only when on) makes Plan Cutting cut each
such slug along the bed's contact lines (grid rows and columns, slat center
lines) before the cutout, so no piece keeps a contact and the pieces drop
between the supports. Each slice stops a kerf short of the cutout, so the
pieces stay attached until the cutout's own kerf frees them together. A
slug the bed holds level, or one on no contact, is left whole; a cutout
holding another part or another of its part's cuts is never sliced.
Slices are break cuts emitted right after the drawing's own break cuts,
pierced on themselves and led straight back to their start. The
released-contour proof now leaves out straight break cuts lying wholly
inside one of the part's closed holes, since the grid cells they free are
scrap; break cuts in material still take part. The plan fingerprint only
changes when the setting is on.
