3c0338f462 fix: wipe tower height crash triggered by H2C/A2L support (#14758)
The new "Prime-tower visits..." test from #14685 (H2C/A2L support) throws
"Coordinate outside allowed range" at random on CI, on both Windows arm64 and
Linux x86_64. It's an uninitialized read of WipeTowerData::height.

#10780 (H2D/H2S) added a second wipe tower path, generate_new(), that fills in
depth, bbx, brim_width and rib_offset but not height. The older generate() sets
height, and clear() never did, so on the generate_new path it stays garbage.

first_layer_wipe_tower_corners() passes height to get_wipe_tower_cone_base() as
R = tan(cone_angle/2) * height. The stray bytes are usually zero, so R is zero
and the slice is fine, which is why it passes most runs on every platform. When
they aren't zero the cone radius runs past ClipperLib's limit and the slice
throws. Nothing selects for it, so it just flakes around.

#14685's test is the first to exercise this path, so that's when it started
showing up.

Initializing height in clear() fixes it, same as the m_origin fix in #13712. The
BBL generate_new path has no stabilization cone, so height = 0 is right.

88262ee504 CLI: guard 4 null derefs when loading a 3mf without preset ids (#14580)
CLI: guard 4 null derefs when loading a 3mf with no preset ids

At OrcaSlicer.cpp:1700-1704 the post-load block reads printer_settings_id,
print_settings_id, filament_settings_id, and nozzle_diameter from the
config that the 3mf carries. If the 3mf is a BBL/BBS-flavored 3mf but
was produced by a non-GUI writer (e.g. CLI --export-3mf without a
loaded preset) any of those keys can be absent, and config.option<T>(...)
returns nullptr — the ->value / ->values deref then SIGSEGVs.

Wrap each optional lookup in an if-let. printer_model, printer_extruder_variant,
and print_extruder_variant already pass create_if_missing=true and are safe.

Repro (BEFORE this patch):
  orca-slicer --export-3mf out.3mf in.stl   # produces preset-less 3mf
  orca-slicer --info out.3mf                # SIGSEGV at :1700
  bt: __cxx11::basic_string::_M_assign
    -> Slic3r::CLI::run @ OrcaSlicer.cpp:1700

AFTER: --info out.3mf returns exit 0 with the mesh summary.

The same failure mode affected --inspect-mesh, --inspect-paint, and
every other action that has to walk the loaded model's config; --slice
would only survive because it always injects a printer via
--load-settings.

4eb9a85a49 Fix filament sync targeting wrong printer after switching printer presets (#12506) (#14587)
For non-BBL host printers (Moonraker/Klipper, Qidi, Snapmaker, Creality), switch_printer_agent() only re-selected the machine when the agent type changed. Switching between two printer presets that use the same agent left the selected machine and the agent's cached device_info pointing at the previously active preset's host, so filament sync kept hitting the old printer.

Re-select the machine when the agent type is unchanged but the target host differs, so the selected machine and device_info always follow the active printer preset.

5a53d2eb88 Fix use-after-free crash on exit during GLCanvas3D teardown (#14588)
Plater's pImpl (unique_ptr<priv> p) is destroyed before the wxWindow base
destructor runs DestroyChildren(), so child GLCanvas3D windows are torn down
after p is gone. GLCanvas3D::~GLCanvas3D() -> reset_volumes() then dereferences
the freed p through two paths:
  - Selection::clear() -> plater()->canvas3D() -> p->get_current_canvas3D()
  - _set_warning_notification() -> plater()->get_notification_manager()

Guard both with the existing wxGetApp().is_closing() flag; both are UI-only
side effects that are no-ops during shutdown, so normal-use behavior is
unchanged.

30aa7d9557 feat(gui): warn when the hotend rack inventory falls short of the sliced plate
Follow-up to the rack-aware pre-print checks: after the blocking checks
pass, warn (without disabling Send) when the plate needs more matching
hotends than the rack printer currently holds - suggesting rack setup,
a nozzle info refresh, or a re-slice to avoid filament waste - or when
the only matches rely on unreliable nozzle information.

Text-only warning rows; this message board has no refresh or
don't-show-again buttons.

2fecfc291f fix(gui): rack-aware pre-print nozzle checks in the send dialog
A print sliced for a nozzle that sits in the hotend rack (but is not
mounted) was blocked by the send dialog's mounted-nozzle diameter check,
even though the printer fetches the required nozzle itself (#14685).

Consolidate the three mounted-nozzle gates (_is_nozzle_data_valid,
is_nozzle_type_match, _is_same_nozzle_diameters) into a single
CheckErrorExtruderNozzleWithSlicing fed by s_get_slicing_extuder_nozzles,
which collects the plate's per-extruder nozzle requirements (hybrid
extruders contribute one entry per used sub-nozzle flow). The rack
extruder validates against its whole inventory (mounted + rack) with
guidance to calibrate the rack, refresh nozzle info, or re-slice, and
blocks when toolhead + rack are full (no free slot to stow a nozzle).
Other extruders keep the validity/flow/diameter checks against the
mounted nozzle.

Also add CheckErrorRackStatus, which holds Send while the printer is
still reading the rack hotend information, and judge material hardness
for the rack extruder per dispatch-mapped nozzle as a non-blocking
caution (mounted nozzles keep the blocking gate).

e98750e713 fix(engine): real-change-only toolchange ordinals and a single M1020 toolchange command
A dual-nozzle H2C print with support filament hangs at its first nozzle
switch. The emitted file shows the change-filament block's M620 O ordinal
jumping from O1 straight to O230, plus a duplicate "M1020 S<n>" toolchange
command right after every change block. Two causes, fixed together because
they interlock (the ordinal check keys off the same toolchange detection
that suppresses the duplicate):

- append_tcr incremented m_toolchange_count once per prime-tower visit
  (roughly once per layer), while the change-filament template only emits
  its M620 O{toolchange_count + 1} line on real filament changes. With 229
  change-less sparse tower layers below the first support layer, the first
  real change reported ordinal 230. The counter now advances only when the
  expanded change block really contains a toolchange command, and the
  placeholder exposes the upcoming change's ordinal (count + 1). The
  set_extruder path already counted per real change and is unchanged.

- toolchange_prefix() returned "M1020 S" for BBL printers, so the
  custom_gcode_changes_tool() dedup could never match the stock profiles'
  line-leading "T[next_filament_id] ..." commands and the writer's own
  toolchange was appended after every change block on dual-extruder
  machines. The prefix is now the plain "T" (the manual-filament-change tag
  branch stays first), and the M1020 form moved into GCodeWriter::toolchange()
  as an explicit branch that also carries the nozzle:
  "M1020 S<filament> H<nozzle>". The nozzle parameter is signed on purpose:
  the null-safe nozzle lookup legitimately yields -1, matching the stock
  templates' own H-1 convention.

The prefix change also lets the CoolingBuffer recognize the change blocks'
T commands as tool boundaries on BBL printers (its per-filament attribution
previously keyed off the duplicate M1020, or nothing at all on
single-extruder models); its existing out-of-range guard ignores
T1000-class machine commands.

Verification: full suites green (libslic3r 48998 assertions / 169 cases;
fff_print 692 / 65 including three new scenarios - writer emission per
printer kind, dedup + ordinal progression on sequential prints, and a
prime-tower regression scenario verified to fail against the old per-visit
counting). Byte gate: 18 of 20 fixtures bit-identical; the sequential repro
differs by exactly its 3 removed duplicate M1020 lines, deterministic
across two runs. Reslicing the field project that exposed the hang yields
M620 O1 followed by a gapless O2..O59 and zero duplicate M1020 lines.

3ebd68d959 feat(engine): per-nozzle-variant machine limits in the time estimator
The time estimator's speed/acceleration limits were indexed by time
mode only, reading slot 0 of the per-(extruder x volume-type) arrays
the multi-extruder profiles already carry (H2C 0.4: 8 entries, H2D
0.4: 10). Every move was therefore modelled with the first machine
slot's limits regardless of which nozzle variant was printing -
estimation fidelity only, since emitted feedrates/accelerations are
decided on the slicing side.

Now the estimator resolves the machine slot of the nozzle currently
mounted in the active extruder: the nozzle grouping context is handed
to the processor BEFORE the streaming replay (new member + setter -
deliberately separate from the post-stream result-field handover that
gates the richer change-time model, whose timing is unchanged), the
occupancy recorder is populated on every filament change (bookkeeping
decoupled from the gated time model; recorder writes have no time
effect), and get_machine_config_idx maps (volume type x extruder type
x extruder) to the slot via the printer's variant layout, newly
carried on the processor result. The feedrate/acceleration getters
gain a slot parameter indexing [slot*2 + mode]; jerk and the
print/travel/retract accelerations stay mode-only. Reloaded sliced
projects re-estimate with the result's saved grouping context;
imported bare g-code degrades to slot 0 - the historical read.

M201/M203 write the parsed value into EVERY slot's mode entry (a
firmware envelope change is global), which keeps per-slot reads in
lockstep with the mode-only reads they replace: the fleet emits
envelope lines before any motion, so estimates - hence the estimated
time header, M73 lines, and every other byte - are unchanged (20/20
pinned-slice byte gate bit-identical, incl. the sequential repro
sliced twice). Fidelity improves where envelope emission is off or a
migrating per-layer plan moves filaments across variants.

Tests: a stub-driven processor case proving the slot follows the
active nozzle through the exact production path (T..H.. commands,
fallback recorder bookkeeping, 4x time ratio on the slow variant),
that emitted M201/M203 reach every slot, and that a missing context
degrades to slot 0. Suites green (libslic3r 48998/169, fff_print
667/62).

582017235c feat(engine): resolve per-variant config columns for raw filament reads on the export path
When a per-layer nozzle grouping migrates a filament across nozzle
variants, the write-back turns two groups of config arrays from
filament-indexed into column-indexed: the per-variant filament options
(one column per variant a filament uses) and the merged extruder
retract overrides (resized to the column count by apply_override).
Export-path readers that still indexed them with the raw filament id
read a neighbor's column for every filament ordered after a migrating
one: toolchange/standby temperatures (M104/M109), retraction lengths
and feedrates, wipe distance, z-hop types, air-filtration keys, and -
through the Extruder's cached flow term - the extrusion E of every
move.

Now every such read resolves its column through the existing
layer-aware resolver (get_filament_config_index ->
Print::get_filament_config_indx), which returns the raw filament id
whenever no per-layer grouping result is published, so static prints
are byte-inert by construction. The Extruder itself has no layer
knowledge, so it gains an injected config column (set_config_index,
default = filament id) that the generator refreshes at the only two
resolution-changing events - layer change and writer toolchange - and
that re-syncs the cached e_per_mm3 flow term. Old-filament reads
resolve at the current layer, which is safe because the per-layer maps
are gap-filled carry-forward. Whole-array placeholder copies
(toolchange temperature overrides) are rebuilt in filament order,
mirroring the existing per-variant placeholder remap. The resolvers
move to the public section so non-friend helpers (ooze prevention) can
resolve too.

Documented, deliberately unchanged: the wipe tower's per-filament
parameter rows (no layer dimension; tower x per-layer grouping is a
follow-up), travel_slope's physical-extruder read, estimator pre-heat
bookkeeping temps, and index-0 header diagnostics.

Verification: new Extruder column-injection scenario (defaults, column
follow + flow-cache rescale, filament-indexed reads unaffected, reset
semantics) and a migrating write-back case proving the column shift for
filaments ordered after a migrator and the resolver tracking it (11 +
14 assertions); suites green (libslic3r 48998/169, fff_print 655/61);
20/20 pinned-slice byte gate bit-identical (incl. sequential repro x2
deterministic).

abbd420f2a feat(engine): write per-variant filament values back for selector regroups
When the per-layer filament selector (enable_filament_dynamic_map)
migrates a filament across nozzle variants (e.g. Standard -> High Flow),
the config write-back only stored the derived extruder map; every
per-variant filament value (retraction, nozzle temperature, flow,
flush...) kept the numbers resolved from the pre-slice static mapping.

Now both dynamic write-back sites (the by-layer branch and the
sequential stitch) branch on the result's dynamic support. Migrating
results run a mixed-filament expansion that regathers every
filament_options_with_variant key from the pristine per-variant
superset, giving a migrating filament one config slot per (extruder
type x nozzle volume type) it lands on - filament_self_index,
filament_extruder_variant, and all value arrays grow in lockstep - and
recompute the retract overrides with per-slot machine indices so a nil
slot falls back to its own variant's machine value. Non-migrating
dynamic results take the merged three-map write-back so re-applies
reproduce from the written maps. Unrouted filaments resolve from the
result's own default map, so slot resolution never depends on
filament_map round-tripping through the plate config.

Print::apply reproduces the identical expansion from the persisted
group result (shared dedupe helper, expansion function, and slot
indices on both sides): the expanded keys sit in the psWipeTower /
psGCodeExport invalidate lists, so without the reproduction every
re-apply after a selector slice would diff non-empty and permanently
invalidate. cal_non_support_filaments now resolves the extruder per
layer from the published result for dynamic groupings.

filament_map_2 keeps its apply-time static derivation; nothing on the
dynamic path reads it (the per-slot machine indices key the override
merge), and per-(extruder x volume-type) machine limits in the g-code
processor remain a documented follow-up.

Every change is gated behind is_dynamic_group_reorder() or a persisted
result with dynamic support; no profile sets the flag, so the static
fleet's instruction stream is unchanged (20/20 pinned-slice byte gate
identical, incl. the sequential repro sliced twice, deterministic).

Tests: expansion unit coverage (migrating slots, unrouted fallback via
the default map, mis-sized volume map ignored, nullable retract keys in
lockstep, slot machine index layout), an end-to-end stub-driven
write-back asserting expanded slots, per-layer config-index resolution,
the override merge incl. the nil-slot variant fallback, and re-apply
stability, plus a real selector slice staying valid across re-apply.
Suites green (libslic3r 48987/168, fff_print 633/60).

c8db06b1d4 feat(engine): stitch per-object selector plans for sequential prints
Sequential (by-object) prints were incoherent with the per-layer filament
selector (enable_filament_dynamic_map): the by-object branch published a
static grouping while each per-object ToolOrdering independently ran the
dynamic planner from an empty nozzle status and wrote its own map to the
config (one write per object, last object wins). The exported toolchange
sequences then disagreed with the published result that drives the
per-layer maps, placeholders, and selector emission.

Now the by-object branch, when the selector is enabled, plans each unique
object once — threading the physical nozzle occupancy and the previous
object's last filament into the next plan — stitches the per-object
per-layer nozzle maps into one print-wide result (gap-filled by the new
normalize_nozzle_map_per_layer so any layer index resolves a filament's
nozzle consistently), publishes it, and writes the derived extruder map
back once. The plans are cached on the Print and g-code export consumes
the cache: the ToolOrdering seed changes the plan input (dontcare
assignment, first-layer reorder), so a fresh export-time construction
could re-plan differently from the published stitch. The per-object
dynamic write-back is gated off for sequential prints.

Every change is gated behind is_dynamic_group_reorder(); no profile sets
the flag, so the static fleet's instruction stream is unchanged (20/20
pinned-slice byte gate identical, incl. the by-object repro sliced twice).

Tests: normalize unit coverage (carry-forward, back-fill, ragged input),
stitched-blocks selector detection, and an end-to-end by-object selector
slice (apply -> process -> export) asserting the published stitched
result, one cached plan per object, the config write-back, and a clean
export. Suites green (libslic3r 48958/165, fff_print 633/60).
