Enable use_forcast in reorder_filaments_for_minimum_flush_volume_base
to match the multi-extruder path behavior (line 1227).
The forecast solver (solve_extruder_order_with_forcast) considers the
next layer's filament set when choosing ordering for the current layer,
minimizing inter-layer transition flush cost.
Previously disabled (hardcoded false) in the single-nozzle/base path,
causing suboptimal inter-layer transitions. The multi-extruder path
already had this enabled.
Measured on 5cubes (5 filaments, 35 layers, H2C):
- Print time: -12 min (-10%)
- Waste filament: -5g (-28%)
- WT extrusion: -44%
Limited to ≤5 filaments per nozzle per layer (O(N!×M!) complexity).
Clamp ramming speed during extruder changes so the departing nozzle
has enough time to reach precool_target_temp before carousel rotation.
Only applies to extruder changes (not carousel nozzle changes).

ramming() L3449-3462
End gcode contains firmware-conditional M400 waits for air purification,
timelapse capture, and sound notification that are post-print operations.
These were incorrectly included in M73 total time, inflating the estimate.
The fix detects MACHINE_END_GCODE_START tag during the streaming parse
(process_tags) and sets m_skip_end_gcode_delays=true. process_M400 then
skips timed delays (S/P params) in the end gcode scope.
BBS achieves the same effect by dropping leftover in calculate_time
(is_final=true). We skip at the source instead, which is more surgical
and leaves calculate_time behavior unchanged for all printers.
Affects all BBL printers with MACHINE_END_GCODE_START tag.
Non-BBL printers are unaffected (no tag = no skip).
Cloud catalog records never carry [tool.orcaslicer.plugin.settings], so the
metadata merge wiped the locally-parsed settings and plugins silently ran on
their built-in defaults (ctx.params arrived empty).
The upstream _make_wipe_tower() tracked purge volumes per-extruder (2 slots),
which collapsed all H2C carousel filaments into one slot and caused massive
redundant AMS flushing (~40g instead of ~0.4g).
Changes:
- Print.cpp: Replace per-extruder nozzle_cur_filament_ids with BBS
NozzleStatusRecorder that tracks per group_id (carousel slot 0..6).
Use get_nozzle_for_filament() to resolve physical slot per layer.
Select filament_prime_volume_nc for nozzle changes, filament_prime_volume
for filament changes (BBS pattern).
- PrintConfig.hpp/cpp: Register filament_prime_volume (per-filament EC prime
volume, default 45mm³) matching BBS PrintConfig.
- Preset.cpp: Add filament_prime_volume to preset keys list.
Safe for non-carousel printers: group_id == extruder_id when each extruder
has one nozzle, so NozzleStatusRecorder behaves identically to the original
per-extruder tracking.

open_terminal_dialog is reached from the plugins dialog's webview
command, and TerminalDialog hosts a webview of its own — same class as
the plugin-window crash. Defer the window work via CallAfter, guard the
re-front Show() per #13657, and drop the redundant Raise() on creation.
wx 3.3.2 delivers webview script messages synchronously inside the native
callback on GTK and macOS, so script plugins run with the plugins-dialog
webview's signal/delegate frame on the stack. Creating and presenting the
orca.host.ui window from there crashed on Linux at Raise() --
gtk_window_present while GTK's deferred show was still in flight.
Defer the whole window creation to a CallAfter with a pre-bound registry
handle (post/close stay FIFO-safe, teardown races become a no-op), and
drop Raise() plus the show_modeless_dialog wrapper: Show() already
activates and fronts a new window on every platform.
Drop the orphaned PluginCallbackList (dead
after the PluginManager migration) and hop
run_on_*_callbacks onto the UI thread via
CallAfter, snapshotting under the mutex on the
worker first. Keeps wx subscribers off the
detached load/unload workers.
