build: clear 53 unused value warnings
49 of them are deliberate i18n markers. L(s) expands to s, so
L("Main Extruder"); is a string literal as a statement and its value is
discarded. The strings have to stay, because the real values come from
printers/*.json at runtime and xgettext cannot scan those. Each block is
now a static const char *const markers[], which uses the values rather
than discarding them. Extraction is unchanged: the xgettext invocation
from scripts/run_gettext.bat gives 76 msgids over the two marker files
before and after, with identical msgid and msgctxt sets.
The other 4 are statements with no effect. AMSItem.cpp:117 and :174
construct and drop a wxColour(255, 255, 255); AMS_TRAY_DEFAULT_COL is
that colour, and the line above already assigns it. UpgradePanel.cpp:865
reads a member and drops it.
wgtDeviceNozzleSelect.cpp:269 writes
if (item; auto ptr = m_nozzle_rack.lock()), which puts the null check in
the init-statement position where its value is discarded, so the check
never runs, and sGetNozzlePosId then dereferences item. Nothing reaches
that today, because the only sender of the event sets itself as the
event object and the dynamic_cast always succeeds. The check now runs.
- Allow mapping to EMPTY trays only from the multi-machine send page and keep
both panels pickable in the LEFT_AND_RIGHT view
- Guard the error-dialog cloud snapshot against stale callbacks and fall back
to the local illustration on timeout
- Parse the ipcam storage-check ack and axis/chamber pushes defensively
- Strip fan-control telemetry, initialize the upgrade error code, restore the
.json filter in the model-id scan
- Fix best-position popup tray lookup, gradient placement, and colour-list
ownership
- Cover switch binding sets and invalid-track transients in DevMapping tests
Nozzle rack data model and device-tab panel, multi-nozzle sync, per-nozzle filament blacklist, and print-dispatch nozzle mapping (DevNozzleMappingCtrl V0/V1).
