The shared estimate reserved every tower with one volume-per-purge rule
and the stability floor. Both planners do more: WipeTower (Type1) wipes
each filament's own prime volume in whole lines, one block per
adhesiveness category sized by its worst layer, rams the leaving
filament at every nozzle change, and squares a rib tower from the
planned depth; WipeTower2 (Type2) spaces its lines by
wipe_tower_extra_spacing, not the Type1-only infill gap, and its extra
flow cancels out of the depth. Both extend the ribs rather than the body
below the stability minimum, size every layer including a thinner first
one, and lay the brim in whole loops, WipeTower reporting half a spacing
of line width on top.
All of that now lives in estimate_wipe_tower_footprint, fed the planner
(resolve_wipe_tower_type mirrors Print::wipe_tower_type and the CLI's
Bambu Lab detection) and the filament ids rather than a count. Print
passes its own tool set; the PartPlate adapter derives the plate's ids
from the passed config and treats an explicit count as a floor, so the
CLI's count-only callers size per filament too. The placement clamp also
reserves a Type2 cone's base bulge, which the body box does not cover.
The planner-mirroring helpers sit beside the planners in WipeTower and
WipeTower2 so the two stay in sync; the libslic3r cases pin them to
footprints measured from generated G-code.
Prime towers reserved depth from the prime volume alone, ignoring the flush
matrix: rib-wall towers in both the engine and the preview, and rectangle and
cone towers in the preview, which never carried the flush-aware estimate the
engine already used. The preview also read the print preset, which does not
carry the printer- and filament-scope keys the estimate needs and so silently
fell back to defaults. On multi-nozzle printers the flush matrix, which holds
one block per nozzle, was additionally read as a single block. The tower could
come out too small for the purge it has to hold.
The flush-based estimate also skipped the height-based minimum depth that the
prime-volume one applies, so low-flush prints could estimate a tower shallower
than the one that actually gets built.
Adds a printer option that picks up the new tool without a blocking temperature
wait, travels to the wipe tower, and waits there right before purging, parked
beside the tower so the ooze from the heat-up lands next to it rather than on the
model. The incoming filament's target is raised ahead of the tool change, so the
heat-up overlaps both the change itself and the travel to the tower.
Off by default, and only offered for multi-extruder printers using a Type 2 wipe
tower; the generic toolchanger profile enables it.
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.
The WipeTower2 code path never called construct_mesh(), leaving
wipe_tower_mesh_data as std::nullopt. GCode export then dereferenced
it unconditionally, triggering an assertion failure / crash.
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.
