b0997f6 moved every cut-off after the parts. Plate.Parts order is the
cut sequence, and the user sets each cut-off's place in it (Set
Sequence), so the post must follow it rather than reorder. Cut-offs
still post as uncompensated open lines with no lead-in.
Multi-sheet nests previously went into one program with a single header
size and one M50 at the end, so sheet 2 would cut into sheet 1's
skeleton. New Sheets settings:
- One program per sheet (default on): JOB.cnc -> JOB-1.cnc, JOB-2.cnc,
each a full program with its own size and pallet change (CL-series
batch rule, EM-423 7.4). Single-sheet nests keep the chosen name.
- Off: one program, with /L "L0" + pallet change between sheets;
mixed sheet sizes are rejected.
- Pallet change code (default M50, unconfirmed for multi-sheet CI Fiber
runs; documented as a release blocker).
All sheets are validated and rendered before any file is written.
IMultiFilePostProcessor lets the desktop app confirm overwrites of every
target file and list what was saved, and the console print each file.
A fixed override wrote the same text on every part, making parts
indistinguishable in the program. Each part's ( PART:... ) comment now
always uses its source file or drawing name. Saved configs that still
contain PartComment load normally; the key is ignored.
System.Text.Json rebuilds MaterialCodes with the default ordinal comparer,
so a saved config matched 'Mild Steel' but not 'mild steel' and silently
fell back to the default code. The setter now re-keys assigned maps
case-insensitively.
Posting a nest with a sheet cut-off threw because the CI Fiber writer
treated every contour as a compensated part contour and requires a
linear lead-in after G41/G42 (TF5200 13.2.4.1). Cut-offs are open
centreline cuts with no lead-in and no inside/outside, so they now post
without G41/G42 and run after every part on the sheet so the sheet is
not severed before the parts are cut (matching the CL post).

New post-processor plugin OpenNest.Posts.CincinnatiCIFiber for the CI
Fiber laser family (nLight CLX / Beckhoff TF5200 / Precitec ProCutter,
e.g. the CI Fiber 4020 8kW). Named by machine family, not table size.
Emits the machine program contract of the Cincinnati-supplied sample NC
(12992-4SS_NEST.nc): V.E.* header, restart jump, per-part V.E.R4 blocks,
per-contour N labels with V.E.R3, skippable /L macro lines (L0/L2+G41
interior, L4+G42 exterior, L6 cut-on, ZHSOFF cut-end), G162 incremental
arc I/J, trimmed 3-decimal spaceless coordinates, CRLF, M50/M30/%.
Contour classification (interior vs exterior) derives from the material
side of the closed cut path, not hardcoded winding. SubProgramCall holes
are flattened to sheet coordinates (rotation-safe). Arc lead-ins are
rejected per TF5200 13.2.4.1 (first motion block after G41/G42 selection
must be linear). Table envelope (default 160.25 x 81.25 in) validated.
Tests: structure golden on a square-with-hole nest, rotated-hole flatten,
coordinate format, arc-lead-in rejection, table validation, suppressed/
scribe skipping, plus a SkippableFact regression against the real sample
NC (109 parts, 2071 contours, L2=1962, L4=109, perimeter vertices match
within 0.001). Fixtures configure through OpenNest.Tests/test-config.json
and the regression skips when absent.
