fix(build): drop two unused lambda captures that break non-Release builds
Both handlers capture this and never use it. They sit inside
#if !BBL_RELEASE_TO_PUBLIC, which CMakeLists defines as $<CONFIG:Release>, so
the code compiles in Debug and RelWithDebInfo but not in Release. Clang warns
on an unused capture under -Wall, and since every warning became an error the
two captures fail any clang build that is not Release - an Xcode scheme on its
default Debug configuration, for instance. The CI matrix builds Release, where
the block does not exist, and GCC does not implement the warning at all, so
nothing in CI can see it.

## 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
```
Fix nozzle diameter guards for printers that don't report nozzle info (#13236)
PR #12814 changed DevNozzle::m_diameter default from 0.4f to 0.0f to
mean "unknown" when firmware doesn't push nozzle info, and guarded two
call sites in SelectMachine.cpp. PR #13330 introduced
DevExtderSystem::NozzleDiameterMatchesOrUnknown() and adopted it in
get_printer_preset / CalibUtils / CalibrationWizardPresetPage. A few
reachable sites were still left out and now report "mismatch" / fail
silently for every non-BBL printer (Klipper/Moonraker, RRF, Marlin,
etc.) that doesn't push BBL nozzle data.
The most visible symptom: the "Sync filament colors from AMS" button on
Moonraker printers with AMS/AFC silently does nothing, because
get_printer_preset() couldn't find a matching system preset (fixed in
#13330, but the lookup-string sites below kept the bug visible
elsewhere).
Apply NozzleDiameterMatchesOrUnknown at the two remaining comparison
sites:
src/slic3r/GUI/Plater.cpp
- file-load printer-mismatch dialog — don't prompt on every load
- on_select_preset sync_extruder_list gate — skip 0.0 extruders
For the three filament-lookup string-builder sites, fall back to the
currently-selected printer preset's nozzle diameter so the dropdown
isn't empty when firmware hasn't reported a diameter:
src/slic3r/GUI/AMSMaterialsSetting.cpp (Popup + on_select_filament)
src/slic3r/GUI/CaliHistoryDialog.cpp (get_all_filaments)
Also remove the dead SyncAmsInfoDialog::is_same_nozzle_diameters method
surfaced while auditing the affected sites — it was introduced
2024-12-30 in commit ad79ed6d93 ("ENH:add SyncAmsInfoDialog",
cherry-picked from Bambu's internal branch) but a caller was never
wired up on the OrcaSlicer side. Dead since introduction.
