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.
build: drop dead private fields, close malformed comments (227 warnings)
Clears 227 of the clang-cl warnings tracked in #15374, taking a full
Windows build from 1,491 to 1,264. Five of the six changes are in
headers, which are re-diagnosed in every translation unit that includes
them, so the count is large for a 14-line diff.
Tabbook.hpp: delete two private fields, unread since the 2022 import.
m_parent also shadowed wxWindowBase::m_parent.
GUI_Utils.hpp: the wxEVT_SYS_COLOUR_CHANGED lambda body is empty on
Windows, so its `this` capture is unused there. (void) this; leaves the
handler bound, which is what stops the event propagating.
DevFirmware.h: mark m_owner [[maybe_unused]]. The class is never
instantiated, and the file tracks BambuStudio, so this is the smallest
divergence.
Eight DeviceTab/ files, AMSItem.cpp and SelectMachine.cpp: block
comments malformed so that they read as a nested /*.
No behavior change. -Wcomment goes to zero, and only the three intended
categories move.
The Filament Track Switch (H2-series accessory, product code O2L-FTS) feeds
every AMS to both extruders through a two-track switch. Port full support
across the device layer, project config, and GUI.
Device / config:
- Model the switch-aware AMS binding (the set of extruders an AMS can feed
and which input track A/B feeds it), switch readiness, the O2L-FTS firmware
module, and the fun2 capability bit for checking a slice against installed
hardware.
- Register has_filament_switcher and enable_filament_dynamic_map as project
config that persists with the project and restores from a saved 3mf, and
force both back to false on every project/printer/CLI load path. Live
device sync is the only thing that sets them true.
GUI:
- Sidebar sync activates the switch from live device state, attributes each
AMS to the extruder its input track feeds, shows a floating status icon
(ready / not-calibrated), and surfaces a one-time tip / not-calibrated
warning.
- Send dialog gains a non-blocking slice-vs-hardware mismatch warning and a
blocking error when a slice needs dynamic nozzle mapping but the switch is
missing or not set up.
- AMS load/unload guards, AMS-view routing glyph + un-calibrated banner +
hidden external-spool road, and mapping-popup external-spool lockout.
- Filament pickers collapse the per-extruder split into a single deduplicated
"AMS filaments" group with a smart-assign toggle when the switch is ready.
- Firmware-upgrade panel lists the O2L-FTS accessory and its version.
- Device-provided filament-change steps (ams.cfs) drive the change-step
display when firmware sends them, including the three switch steps.
- "Load current filament" asks which extruder to feed via a
FeedDirectionDialog when the switch is calibrated.
Inert without the accessory: every path is gated on the switch being
installed (MQTT aux bit 29, default off) or ready, both project flags default
false, and the per-extruder AMS attribution is byte-identical, so AMS state,
the send/load UI, and sliced g-code are unchanged for every printer that does
not report a Filament Track Switch.
