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.

Tabs suit thin plate, but on anything thicker than 0.25 in the parts
are too hard to break out of the sheet, and the Cutting Parameters
dialog was one global set for every job. Its settings now live on the
nest's machine thickness: leads on the existing Outside/Inside Cuts
tabs, and lead-in angle rounding, tabs and pierce on a new Tabs &
Pierce tab (ThicknessConfig.Cutting). In Database mode every
workstation gets the same settings through the shared machine.
The dialog and the Place Lead-in panel say what they edit, and save
back to that thickness (MachineCuttingDefaults.WriteTo, converted to
the machine's units). A thickness with no Tabs & Pierce of its own, or
a nest the machine has no thickness for, keeps this PC's settings as
before. If the machine can't be saved (server offline, a conflict),
the edit is kept on this PC for that job and the user is told.
Machine Configuration can copy one thickness's Tabs & Pierce to
thinner or thicker ones, so the 0.25 in rule takes a few clicks.
An older desktop saving a shared machine would silently erase these
settings, since it doesn't know them. Machine configuration classes
now keep unknown fields, and the server refuses a machine save that
leaves out a field the stored machine has a value for, telling the
user to update OpenNest.
The Plan Cutting status line now reports tabs from SupportTabs; since
"Tab every part" was retired it always said off.
