The dry drag-out and the flat-ironing spiral could leave the margin band no
tower envelope accounts for (the ironing area is unbounded user input);
truncate them to WIPE_TOWER_MARGIN around the tower outline instead of
skipping the scrub.
Share one wait_for_temp_enabled gate between the tower and append_tcr2 so a
SEMM profile carrying the flag keeps its blocking ooze-prevention wait.
Park beside the tower on custom polygonal beds via point-in-polygon, clamp
the near-side park toward the bed edge before crossing to the far side, and
start non-blocking heating at the toolchange when ooze prevention emits
nothing so heat-up overlaps the travel.
With the gap wall on a multi-tool printer, quantize the ram band up to its
whole reserved rows (as the BBL tower does for the old-tool purge) and start
CP TOOLCHANGE WIPE at the left-edge boundary on a fresh row below it instead
of continuing from wherever the ram serpentine ended. The entry scrub then
runs at the wall gap on ram toolchanges too, and the wipe box is whole rows,
so it is filled completely like the no-ram case. SEMM and skip-points-off
behavior is unchanged.
The entry scrub now matches the BBL tower's toolchange_wipe_new sequence:
after the ironing drag the retracted nozzle runs a dry expanding-square
spiral centred on the wall-gap entry point before resuming the purge row.
The spiral runs whenever the gap wall is on (disable per filament via
filament_tower_ironing_area = 0); WipeTower2 no longer reads
prime_tower_flat_ironing.
Without ramming, each purge block reserved one wipe pitch more than its
rows occupy (ceil+1 rounding plus the ram-geometry start offset), and the
wipe began a full pitch inside the block, leaving a blank band of exactly
two pitches between adjacent blocks. Plan the block as whole wipe rows,
start the first row so the row lattice continues across the block
boundary, and fill the reserved box instead of stopping at the ordered
volume, mirroring how the BBL WipeTower keeps planned depth identical to
printed rows. Ram-printing toolchanges (SEMM with ramming enabled,
multitool ramming) are unchanged.
The planner reserved ramming rows gated only on enable_filament_ramming and
sized them with the SEMM 0.25s time step, while toolchange_Unload rams on
(semm && enable_filament_ramming) || filament_multitool_ramming with the
multitool time step. Disabling multitool ramming therefore left ~3 unprinted
rows per toolchange as blank bands in the tower. Without ramming the first
wipe line also needs reserved depth of its own (it no longer rides the last
ramming row), plus the y_step/2 offset the wipe start inherits from the
ramming start position - otherwise the tightened boxes truncate the ordered
purge at the box edge.
Port the BBL tower's entry line ironing: extrude the first 3 mm of the
purge, retract, drag the nozzle 1.5x back out through the wall gap at
F600, creep back at F240 and unretract, so the toolchange start blob
ends up in the gap instead of on the wall. Fires only when the purge
starts at the left-edge entry heading right (in-place toolchangers);
SEMM ram/cooling wipes start mid-box and the priming line has no wall,
so both keep their previous output.
prime_tower_skip_points was stubbed for Type2 towers: the wall call
hard-coded skip_points=false, the gap cutter received an empty vector,
and append_tcr2 never routed the entry travel. Now the toolchange entry
positions are precomputed from the finalized plan, the wall is cut open
at each entry, and the entry travel approaches around the tower bounding
box through the opening when it starts outside the tower. The geometry
helpers are re-synced with the BBL versions (add_extra_point guards,
per-point side selection). The cone wall keeps its separate path, where
the option stays inert.
Behavior change: non-BBL towers now honor the (default-on) checkbox with
gap walls and routed entries; with the option off the output is
unchanged, and the BBL tower path is untouched.
Like the BBL tower: the layer's sparse infill, wall, and brim go to the
first toolchange to a non-support/non-soluble filament, or are printed
with the incoming filament before any toolchange. The minimal-purge
clamp now also covers toolchanges that get no finish-layer saving.
Output is unchanged when no support/soluble filament is used.
The rib tower is now always square (prime_tower_width is ignored, as the
GUI already implies), carries the rib origin offset like the BBL tower so
the rib tips sit inside the configured position, clamps the rib length to
the tower diagonal, and extends the ribs for short towers.
When a per-layer nozzle grouping migrates a filament across nozzle
variants, the write-back turns two groups of config arrays from
filament-indexed into column-indexed: the per-variant filament options
(one column per variant a filament uses) and the merged extruder
retract overrides (resized to the column count by apply_override).
Export-path readers that still indexed them with the raw filament id
read a neighbor's column for every filament ordered after a migrating
one: toolchange/standby temperatures (M104/M109), retraction lengths
and feedrates, wipe distance, z-hop types, air-filtration keys, and -
through the Extruder's cached flow term - the extrusion E of every
move.
Now every such read resolves its column through the existing
layer-aware resolver (get_filament_config_index ->
Print::get_filament_config_indx), which returns the raw filament id
whenever no per-layer grouping result is published, so static prints
are byte-inert by construction. The Extruder itself has no layer
knowledge, so it gains an injected config column (set_config_index,
default = filament id) that the generator refreshes at the only two
resolution-changing events - layer change and writer toolchange - and
that re-syncs the cached e_per_mm3 flow term. Old-filament reads
resolve at the current layer, which is safe because the per-layer maps
are gap-filled carry-forward. Whole-array placeholder copies
(toolchange temperature overrides) are rebuilt in filament order,
mirroring the existing per-variant placeholder remap. The resolvers
move to the public section so non-friend helpers (ooze prevention) can
resolve too.
Documented, deliberately unchanged: the wipe tower's per-filament
parameter rows (no layer dimension; tower x per-layer grouping is a
follow-up), travel_slope's physical-extruder read, estimator pre-heat
bookkeeping temps, and index-0 header diagnostics.
Verification: new Extruder column-injection scenario (defaults, column
follow + flow-cache rescale, filament-indexed reads unaffected, reset
semantics) and a migrating write-back case proving the column shift for
filaments ordered after a migrator and the resolver tracking it (11 +
14 assertions); suites green (libslic3r 48998/169, fff_print 655/61);
20/20 pinned-slice byte gate bit-identical (incl. sequential repro x2
deterministic).
Wipe tower interface features and preheat fixes
Fresh PR branch rebuilt on upstream/main (squash of origin/BBL-studio-wipe-tower-merge) to avoid merge-history issues.
Sorry had to re-create the PR as I did some chaos in my repo with CLI. xD
Fixes issue https://github.com/OrcaSlicer/OrcaSlicer/issues/10971
Description:
Fix wipe tower filament selection and clean up tool ordering. Added wipe_tower_filament handling to WipeTower2 (store config, mark non-selected tools as “soluble,” and use it in toolchange selection) and ensured the configured wipe‑tower extruder is included in the extruder list for ordering. Removed duplicated/merged tool‑ordering code (extra insert_wipe_tower_extruder definition, duplicate declaration, and redundant reorder block) so the tool order logic runs only once.

# Description
Fix application freeze when Prime Tower brim is set to Auto
This PR fixes an issue where enabling Auto brim width for the Prime Tower caused the application to freeze and consume unbounded amounts of memory.
Root cause
0c5f6c9865/src/libslic3r/GCode/WipeTower2.cpp (L2036-L2039)
When Auto brim is selected, the brim width was not being computed and the raw configuration value (-1) was used directly.
This resulted in an effectively infinite loop during Prime Tower brim generation, leading to runaway memory allocation instead of a controlled failure or a crash.
Solution
The Auto brim width is now properly computed based on the Prime Tower height, matching the intended behavior and existing logic used in other slicer implementations.
* Enhance GCode handling for Z-axis movements
- Updated `travel_to_z` method to include a `force` parameter, allowing forced Z movements.
- Modified GCode generation logic to ensure Z position is restored after unknown last positions.
- Enforce z restoreation after tool changer
* Improve filament_multitool_ramming logic
* fix indent
and modify the path of travel to the wipe_tower after flushing
