Clifford GarwoodandClaude Opus 5 5eac300d91 Use IDEX/IQEX in the user-facing strings
Closes review comment 10.

`461c69c83e` settled this in April — IMEX internally, IDEX/IQEX as the user-facing label — but the
UI strings were never converted. Every translated string naming the feature now reads IDEX/IQEX:
41 occurrences across the printer and process option labels and tooltips, the modes editor, the
plate mode indicator, the pre-slice warnings, the placement refusals and the slicing errors. The
reviewer listed eight; the rest were in the same class.

Nothing else moves. The config keys keep the `imex_` spelling — `is_imex`, `imex_mode_names`,
`imex_parallel_mode` and the rest are on-disk format in existing printer presets and 3MF projects,
so renaming them would break every profile and project already saved. C++ identifiers, filenames,
comments and test names keep IMEX as well: it stays the internal name of the subsystem, which is
what covers the topology space (one gantry with 2-4 tools, 2x1 and 2x2 grids) that neither acronym
names on its own. Where a tooltip quotes a key, the key spelling is preserved and only the feature
word around it changed.

The `is_imex` tooltip is reworded rather than substituted: it already named the hardware families
parenthetically, so a literal replacement would have said IDEX/IQEX twice in one sentence.

No translation impact — no IMEX string had reached OrcaSlicer.pot or any catalogue, so there is
nothing to migrate. One test asserted on the old error text and now matches the new one.

Clifford GarwoodandClaude Opus 5 bd8dfd6250 Cover the IMEX slice offset, the mode G-code placeholders, and the non-IMEX heater guard
Closes review comments 13, 14 and 15, and adds the test for a shipped-profile
regression that nothing guarded.

- 14 and 15: compute_imex_slice_offset had eight tests on the calculation and none
  on the result, which is the whole firmware-managed path. test_imex_slice_offset
  now covers the derivation end (which config produces a non-zero offset, and that
  it is plate-local rather than moving with the plate origin -- the bug that
  shifted every plate after the first) and the consumption end (emitted
  coordinates and first_layer_print_min/max both move by the derived amount).
  The first_layer case also cross-checks the two consumers against each other: the
  declared bounds must keep the same relationship to the emitted toolpaths in both
  frames, which fails if exactly one of them is shifted. It deliberately does not
  pin the size of that gap -- it is 2.225 mm here, set by the wall generator, the
  same with no offset at all, and pinning it would fail on an unrelated change.
- 13: nothing exercised the imex_mode / imex_mode_index / imex_mode_gcode
  placeholders or the {global} flow into machine_start_gcode that their ordering
  exists to guarantee. Seven cases now do, including the ordering itself -- the
  mode script declares a global and machine_start_gcode reads it back, so moving
  the mode processing later leaves the variable undefined and fails the export --
  plus the inert cases (Primary mode, and a printer with the table filled in but
  is_imex off). All matching is whole-line, because the config block the exporter
  appends repeats machine_start_gcode verbatim and would make substring checks
  meaningless.
- New: GCodeWriter passes this->config.is_imex.value into the heater remap, and
  nothing tested that it passes the flag rather than a constant. Hardcode true
  there and the whole suite stays green while fdm_bbl_3dp_002_common, which ships
  physical_extruder_map [1,0], starts sending filament 0's M104/M109 to heater 1.
  The new case runs a two-nozzle non-IMEX printer with that map and asserts each
  filament's temperature reaches only its own tool. It uses idle_temperature via
  ooze prevention rather than nozzle_temperature: keys in
  filament_options_with_variant are re-indexed per filament by variant slot at
  apply time, and this harness pins nozzle_diameter to one value, so every filament
  resolves to the same slot and the temperatures stop telling the heads apart.

Also fixes two weaknesses in tests added earlier in this branch: an assertion that
would have been prefix-satisfied by the very routing it was meant to exclude, and
a whole-file command comparison between two slices, which this slicer's output is
not stable enough to support.

Clifford GarwoodandClaude Opus 5 018091f43b fix(imex): let the mixed-filament refusal outrank the multi-color rule
A mixed filament is unsupported in a parallel mode outright, but the rule saying
so ran third. A plate carrying a blend plus any second filament tripped the
multi-color rule's used > 1 gate first and was told its active tools all sit on
one gantry -- a diagnosis of a multi-color print the user never configured,
whose remedy is to go rework the mode's tool roster. The blend was never
mentioned. Move the check ahead of both rules below it; being unsupported
regardless of routing or topology, it dominates them.

Nothing is masked that leads anywhere else: every branch of
imex_multicolor_block_reason is itself confined to non-primary modes, so the
mixed message's remedy -- switch this plate to Primary -- silences those too.

Say "Mixed filaments", not "Blended". Every other string in the app calls these
mixed, including the button that creates one and the sibling refusal for the
wipe tower filament, so the user had no way to connect the message to the
feature it names.

Three comments in the block were wrong, and two of them were newly wrong. The
routing rule's bounds-check note still said "Blended slots are out of range by
construction, but they never reach here -- the rule above returns first": the
rule above is now the multi-color one, which does not return first for a single
mixed filament, and out-of-range is not guaranteed at all. Mixed slots are kept
at the tail of the filament arrays by convention, not by enforcement --
PresetBundle::set_num_filaments grows filament_is_mixed with resize(), so
raising a printer's extruder count with a blend present lands physical slots
after the mixed one. The scan is position-agnostic and stays correct; only the
stated reason was wrong.

The same discovery makes the empty-routed_list guard live rather than the dead
code it was described as. Print::apply() normalises physical_extruder_map before
validate() runs, so an unauthored map is never the cause -- but a printer with
more filaments than logical extruders leaves the tail slots outside the map, and
raising the extruder count does exactly that.

The new test validates the plate twice. The first pass, with no blend, asserts
the multi-color rule is armed at all; without it the second proves nothing,
because the rule only fires here thanks to a degenerate fixture mode whose two
tools share a gantry. Give that mode a Span tool and the whole test would pass
under either ordering while appearing to guard it. It also pins err.object,
which the mixed path sets and the multi-color path leaves null -- a discriminator
that survives the next wording change. Verified by reverting the order: the test
fails on both the message and the object.

Clifford GarwoodandClaude Opus 5 2e883df7d9 fix(imex): name the physical head in M104/M109 tool indices
M104/M109 address a heater, but every caller of the instance
GCodeWriter::set_temperature overload addresses filaments by logical id, so on a
printer whose physical_extruder_map is not the identity the emitted T named the
wrong head -- or, where the logical id exceeds the head count, no head at all.
With a map of 0,0,0,0,1,2,3 a toolchange to filament 5 emitted "M109 S265 T4"
and "M104 S190 T4 ;cooldown" while the head it meant was T1.

Upstream already treats these commands as physical: the preheat it injects in
GCodeProcessor maps through the same map before emitting, and BBS's own wipe
tower does likewise. Emitting logical is the half that never got the memo.

That mismatch also disabled the cooldown suppression beside the preheat, which
compares the line's T against pem[tool_number] and so never matched a logical
one -- 171 cooldowns survived in a two-head print where none should have. Worse,
it could match the wrong line: a cooldown for filament 1 emitted T1, and a
toolchange to filament 5 gives pem[4] == 1, so a legitimate cooldown for head 0
was deleted because the incoming head happened to be numbered 1.

Translate once, in the instance overload every logical-space caller passes
through. The static overload is already physical-in and is left alone.

Gated on is_imex. physical_extruder_map carries two readings in this tree: the
BBS paths index it by extruder id, the IMEX paths by filament id, and the two
coincide only when the filament and nozzle counts match. Mapping unconditionally
would impose the IMEX reading on profiles that mean the other one --
fdm_bbl_3dp_002_common ships a non-identity [1,0], spared today only because
single_extruder_multi_material suppresses the T qualifier entirely.

The wipe tower's interface-temperature pass has to move with it. It strips the
M109 that post_toolchange emits by searching for that filament's tool index, so
it now searches for the mapped one; left alone it would have stopped matching,
and the surviving blocking M109 would have silently defeated the interface
temperature. Its sibling pass reads WipeTower2 output, which emits no T at all,
and is deliberately unchanged.

The bare T<n> toolchange stays logical -- it selects an AFC lane, not a heater.

Test slices two objects across a head boundary, the only case that reaches this
emission: the same-physical short-circuit in set_extruder suppresses the
cooldown entirely for lane swaps within one head. It scans every M104/M109
rather than matching fixed strings, so it catches any unmapped emission and not
just the two sites changed here. With the mapping neutered it reports 101
offending lines; with it in place, none.

Clifford GarwoodandClaude Opus 5 f0778ef5fa fix(imex): shorten the off-primary message and block blended filaments
The routing error ran to roughly 450 characters and explained the mechanism
before it got to the remedy. It also offered to "edit the mode in Printer
Settings so its Primary tool is one of %3%", which on a plate whose filaments
resolve to no head at all rendered as "one of no configured extruder". Cut it
to the mode, the tool it prints with, where the plate's filaments actually are,
and the two things the user can do about it.

The second msgid that named candidate modes went with it. It could only suggest
a mode whose primary is among the routed heads, and every mode on the printers
this fires for declares 0:P, so it had nothing to offer.

Blended filaments now return before that check rather than falling through it.
A blend is mixed at the nozzle by its component toolheads, and a parallel mode
is already using those toolheads to print copies or mirrors, so the two cannot
run at once regardless of where the components route -- including when a
component sits on the declared primary. Reaching the routing rule would also
have described them wrongly: mixed slots sit past the end of
physical_extruder_map, so they resolve to no head and read as merely unrouted.

Keeps the empty-list guard the shortening first dropped. validate() reads the
raw physical_extruder_map, whose registered default is a single entry, so a
profile that declares IMEX modes without authoring a map leaves every slot past
the first outside it -- and the sentence ended in a dangling "on .".

Clifford GarwoodandClaude Opus 5 baef398ee3 fix(imex): refuse a plate whose filament cannot reach the mode's primary tool
The IMEX primary tool prints the sliced paths directly, so it can only load a
filament that physical_extruder_map routes to it. The ghost filament picker
enforces that for the secondary tools -- it offers only lanes whose pem entry
equals that head -- but the primary's filament comes from the ordinary object
filament selector, which has no IMEX awareness. Nothing detected the mismatch:
collect_imex_warnings() computes the same condition and discards it into a
display fallback, and the multi-color rule never examines it.

Block it in Print::validate() via the existing imex_primary_tool_for_mode and
imex_primary_logical_from_objects helpers. The message names the declared
primary, the heads the plate's filaments actually live on, and any configured
modes whose primary would work, and carries the object so the notification can
offer a jump to it.

Blocks rather than warns, matching the multi-color rule: the plate is not
printable as configured, and where the routed head is also absent from the
mode's active tools the 1st->2nd layer temperature branch skips it too, leaving
that head at its initial-layer temperature for the whole job.

The multi-color check now runs first. Its constraints -- an MMU manifold sharing
one head, a single-gantry mode -- cannot be fixed by switching mode, so the more
specific error should win rather than be masked by routing advice that leads
straight back to it. The extruders().size() > 1 gate moved onto that call, since
the routing check must also see single-filament plates, which is its common case.

The copy-mode guard-rail test printed on a filament routed off the primary, so
it asserted a plate this rule now refuses; retargeted to a well-formed plate.
Its replacement pins the object's own extruder, because ModelVolume reports its
extruder_id and would otherwise put a primary-routed slot on the plate.

Clifford GarwoodandClaude Opus 5 ef8d80980d fix(imex): enumerate no secondary carriages in single-tool primary mode
get_imex_active_tools returned every physical head named by the active mode's
tool string, including the one carrying the Primary role. The pressure-advance
and nozzle-temperature sites are already gated on the mode not being primary, so
only the is_extruder_used supplement was exposed.

In primary mode that supplement treated the mode's single declared tool as a
secondary carriage and marked its filament slot used, so machine_start_gcode
emitted a heat command for an extruder that never prints. The phantom slot
appears when the mode's declared tool differs from the head the initial tool
routes to through physical_extruder_map -- on an AFC/MMU layout, printing with a
filament that lives on any head other than the declared one.

Return an empty roster for primary mode, where there are no parallel carriages by
definition. This lives in the enumerator rather than at the call site because the
mode is already resolved and normalized there, and the two guarded callers cannot
reach it in that mode, so their behaviour is unchanged.

Scope: this closes the primary-mode instance. The same phantom slot still occurs
in a parallel mode when the initial tool's head is not the mode's declared
Primary, which turns on which of the two notions of "primary" the three emission
sites should skip. That question is unresolved and deliberately left alone here.

Clifford GarwoodandClaude Opus 5 c94e8324d0 fix(imex): give the printing head its second-layer temperature in parallel modes
The IMEX branch of the 1st->2nd layer temperature transition is mutually
exclusive with the standard per-extruder path in its `else`, but it skipped the
head carrying the print's own toolpaths on the premise that "the standard
per-extruder temp path already addresses it". That path is the `else` branch and
never runs for a parallel mode, so the printing head received no transition at
all and held nozzle_temperature_initial_layer for the entire job.

Emit for every carriage the mode drives, the printing one included. The printing
head takes this layer's own filament; the parallel carriages, which carry no
toolpaths of their own, keep resolving through the per-plate head map with pem
inversion as the fallback. The lookup now goes through get_filament_config_index()
like the standard path, since a variant-expanded printer gives a filament its own
column and a raw index would read the wrong one.

Reproduced on a 4-carriage IQEX in copy mode: the only temperature command in the
whole file set the idle secondary carriage to the value it already had, while the
head doing the printing never left its first-layer temperature. The defect is
invisible whenever initial and regular temperatures match, which is why earlier
per-tool validation passed.

Tests cover both gantry counts, since the active set comes from the mode's tool
roster: an IDEX copy mode drives two carriages, an IQEX mode drives four, and the
IQEX case asserts a first-layer filament and a second-layer transition for each of
the four.

Clifford 8e243faa3a Fix Linux unit test failure in the wipe tower temperature trace comparison (#15161)
## Problem

`Toolchange temperature commands are unchanged when the wipe tower wait
is off`
(added in #15144) fails on both Linux runners and passes on Windows and
macOS.
It is the only failing test in the suite, and it has been failing on
main since
that PR merged.

| Job | Result |
| --- | --- |
| Windows x64 / Unit Tests | pass |
| Windows arm64 / Unit Tests | pass |
| macOS arm64 / Unit Tests | pass |
| Linux x86_64 / Unit Tests | **fail** |
| Linux aarch64 / Unit Tests | **fail** |

From the merge commit
([Linux
x86_64](https://github.com/OrcaSlicer/OrcaSlicer/actions/runs/31072382258/job/92531704095),
[Linux
aarch64](https://github.com/OrcaSlicer/OrcaSlicer/actions/runs/31072382258/job/92531704075)),
still reproducing on current main:

```
first difference at trace entry 29
  main:   M104 S240 T0 ; preheat T0 time: 31s	lead 30.9s
  branch: M104 S240 T0 ; preheat T0 time: 30s	lead 30.3s
```

## Cause

Each preheat entry records the same quantity twice: `lead` at one
decimal, and
`time:` inside the command text as that value rounded to a whole second.

`split_lead` already compares `lead` with a 0.5s tolerance and explains
why the
estimate moves. `time:` sits in the exactly-compared command text, so it
never
got that tolerance — and being rounded, it flips on a drift far below
0.5s
(30.4 and 30.6 render as `30s` and `31s`). Entry 29 is the only entry in
the
163-entry golden whose lead rounds up; every other preheat sits at
30.0–30.4 and
rounds down, which is why it is the only one that fails.

The variation is per-toolchain, not run to run. Both Linux arches
produce
exactly `lead 30.3s`; Windows x64/arm64 and macOS arm64 all produce
exactly
`30.9s`. Repeated local runs are byte-identical. macOS arm64 passing
while Linux
aarch64 fails rules out the ISA — it is floating-point accumulation over
a few
thousand move durations under GCC vs Clang vs MSVC.

The mechanism makes it discrete rather than gradual: the backtrace parks
the
preheat at the first exported line at least `preheat_time` before the
tool
change, so `lead` is `preheat_time` plus the leftover of whichever move
that
landed on. A sub-tenth difference selects the neighbouring move and
`lead` steps
by that move's whole duration.

Entries 1–28 match exactly, including five earlier preheats whose leads
fall
inside the existing tolerance, so the toolpaths themselves are
identical. I also
reverted the two prime-tower commits that landed between the golden's
capture
point and now, rebuilt, and got a byte-identical trace — this is not
behavioural
drift.

That also rules out regenerating the golden: no single capture satisfies
all
three toolchains, and recapturing on Linux would turn the three
currently-green
runners red.

## Fix

Test-only.

- `lead` keeps a tolerance, widened to 1.5s (measured drift 0.6s; a
preheat
actually leaving its backtrace position would move by tens of seconds).
- `time:` is **not** compared across runs at all. Being a rounding of
`lead`, it
carries nothing the tolerance does not already cover, and comparing it
across
runs can only reproduce the flake. It is instead checked against its own
  entry's `lead` — a correct rounding keeps `|time - lead| <= 0.5`.

That second point matters: simply tolerating `time:` numerically would
have made
the test blind to a real change, because drift and a wrong rounding both
move it
by 1. The self-consistency check keeps that coverage. I verified it by
changing
`(int) std::round(time_diffs[0])` to `(int) time_diffs[0]` in
`GCodeProcessor::export_lines` — the test fails with
`"time:" is not its entry's "lead" rounded to a whole second`, where a
plain
tolerance would have passed silently.

Everything else is still compared exactly: all M104/M109 values, tool
ids,
block markers, ordering, entry count, and the annotation text including
its
trailing `s`. The other 138 entries remain byte-exact.

No production code, no golden regeneration. The golden file and these
helpers
are used by this one test and nothing else, and the tolerance only
widens, so
Windows and macOS keep passing unchanged. A note is added to the
golden's header
so the next mismatch in those fields is not "fixed" by recapturing.

## How to verify

Before, on Linux:

```bash
git checkout main && ./build_linux.sh -t
ctest --test-dir build/tests -R "Toolchange temperature commands are unchanged" --output-on-failure
# fails at trace entry 29
```

After:

```bash
cmake --build build --config Release --target fff_print_tests
ctest --test-dir build/tests --output-on-failure     # 463/463
```

SoftFever 408db4b3b0 Wait for the toolchange temperature on the wipe tower
Adds a printer option that picks up the new tool without a blocking temperature
wait, travels to the wipe tower, and waits there right before purging, parked
beside the tower so the ooze from the heat-up lands next to it rather than on the
model. The incoming filament's target is raised ahead of the tool change, so the
heat-up overlaps both the change itself and the travel to the tower.

Off by default, and only offered for multi-extruder printers using a Type 2 wipe
tower; the generic toolchanger profile enables it.

Kris Austin 6fda82476d fix: out-of-bounds read computing tool-ordering max layer height (#14665)
* fix: out-of-bounds read computing tool-ordering max layer height

calc_max_layer_height() loops over the extruder count (nozzle_diameter)
but indexes max_layer_height with the same counter, reading past the end
when that array is shorter. Silent on release builds, aborts under a
bounds-checked STL (_GLIBCXX_ASSERTIONS).

Read via get_at(), which falls back to the first entry when the index is
out of range, as Slicing.cpp already does for this option.

Add a fff_print regression test slicing a two-extruder printer with a
single-entry max_layer_height.

* docs: clarify how max_layer_height ends up short in the regression test

Normalization sizes it to the filament count under single_extruder_multi_material,
not "a mismatch a profile can ship" as the earlier comment guessed.

raistlin7447 29f31b9b38 fff_print: a maintainable testing framework (proposal + coverage) (#14426)
* fix: initialize Print::m_isBBLPrinter

Built outside the GUI/CLI (headless tests, embedded use) the member was read
uninitialized: is_BBL_printer()/wipe_tower_type() feed it into ToolOrdering,
which then non-deterministically dropped per-feature filament assignments.
Default it to false, the value the GUI and CLI already assign for non-Bambu
printers.

* docs(test): add the fff_print testing contract

tests/fff_print/README.md codifies how the suite is organized: one file per
subsystem (each owning both in-memory and emitted-G-code assertions), flat
behavioral test names with a single [Subsystem] tag, a robust-tests guide,
the shared helpers, and an add-a-test checklist. Linked from tests/CLAUDE.md.

* test(fff_print): reorganize the suite to the contract and add coverage

Bring every subsystem into one file per the README: rename the test_data
harness to test_helpers; consolidate skirt/brim; split multi-filament and
cooling into their own files; disperse the test_printgcode grab-bag and the
end-to-end smoke scenario into focused tests; fold test_gcode into
test_gcodewriter. Standardize names and tags, align cube tests on the cube()
helper, and de-qualify the flagship files.

New coverage: multi-filament per-feature and per-object routing; a skirt/brim
behavior matrix (the #14333 rework, including brim ears, with regression
coverage for #14319 and #14366); resolved extrusion-width and config
comments; custom-G-code placeholders; fan control and speed-marker
consumption.

Re-enable three slice tests previously tagged [NotWorking]: the clipper
"Coordinate outside allowed range" error that disabled them was specific to a
past CI runner environment and no longer reproduces.

* test(fff_print): tag arm64-flaky skirt/brim tests NotWorking

Four skirt/brim slice tests intermittently throw ClipperLib's "Coordinate
outside allowed range" on the macOS and Windows arm64 CI toolchains (an FP
divergence, not a slicing bug; see PR #14207). Linux x86_64 and aarch64 are
unaffected. Tag them [NotWorking] so ctest -LE NotWorking skips them.

* test(fff_print): re-enable the arm64 skirt/brim tests

These were tagged [NotWorking] as a stopgap when myfork's daily-driver build
combined them with the cross-platform CI on a base that predated upstream's
m_origin fix (99dea01cc3). With upstream merged in, Print::m_origin is
initialized and the "Coordinate outside allowed range" throw is gone, so the
tests pass on macOS/Windows arm64. Drop the tags.
