On Linux every account shares /tmp, but slicing builds temp paths there under
fixed, app-owned names via temporary_dir() (model backups, STEP import,
part-skip). The first user to slice creates and owns those dirs, so the next
user cannot write under them and slicing crashes with "No such file or
directory".
Tag the app temp root with the user id at startup (<temp>/orcaslicer_<uid>)
so every temporary_dir() consumer is isolated at once. The id stays at the
top level of the world-writable system temp so each user's dir is created
directly there; a shared parent dir would be owned by whichever user made it
first. The root is pre-created because STEP import writes into it directly.
Windows keeps the plain temp dir since it is already per-user.
Fixes#10108. Same root cause as #5969.
* fix profile reference for Creality
* fix profile reference for Blocks
* fix profile reference for OrcaArena
* fix profile reference for re3D
* fix profile reference for Chuanying
* fix profile reference for Prusa
* fix profile reference for Wanhao France
* fix profile reference for MagicMaker
* fix profile reference for Afinia
Remove the ABS/ABS+/PLA/TPU/Value ABS/Value PLA filament presets that referenced the non-existent "Afinia H400 Pro" printer. The real printer is "Afinia H+1(HS)", already served by the @HS filament variants.
* fix profile reference for Comgrow
Remove the orphaned "0.20mm Standard @Comgrow T500 1.0" process preset and its process_list entry. Its only compatible printer "Comgrow T500 1.0 nozzle" never existed (the T500 model defines nozzle diameters 0.4/0.6/0.8 only).
* always run check_preset_references
The 409 conflict notification, the force-push confirmation dialog, and the payload-too-large (413) dialog now name the affected preset. The name was already parsed from the conflict body but never surfaced. The account-level preset-limit message stays generic since it isn't about one specific preset.
* Fix reload from disk for STEP models after reopening a project (#12992)
reload_from_disk matched reloaded source volumes with an exact
source.input_file string comparison. After a project is saved and
reopened, the stored source path is only the filename (the default,
non-full-path save) while a freshly re-imported volume carries a full
path, so the comparison never matched: reload fell into fail_list and
the "locate file" dialog was effectively useless for STEP models.
Fall back to a case-insensitive filename comparison when the exact
paths differ, so the existing same-folder source lookup (and the
locate dialog) can reload the model. Projects that stored absolute
source paths still match exactly as before; no 3mf format change.
* Add Preferences option to store full source paths in projects
Expose the existing export_sources_full_pathnames setting (previously
only editable in the config file) as a checkbox under Preferences >
General > Project. Enabling it stores absolute source paths in saved
projects, so "Reload from disk" works when the source file is kept in
a different folder than the project (companion to #12992).
Introduces a plugin capability that runs Python at the seams of Print::process(),
letting a plugin read and rewrite slicing state as it is computed.
- New slicing_pipeline_plugin config option; selected plugin refs are serialized
into the print manifest.
- Print gains an injectable hook fired at each pipeline step (posSlice,
posPerimeters, posInfill, ...). It is a no-op when unset, fires only on genuine
(re)computation, and never on the use-cache path.
- orca.slicing submodule: SlicingPipelineCapabilityBase plus a trampoline and a
Step enum. Capabilities read the live graph through zero-copy int64 numpy views
(contour/holes geometry with unscaled coordinates, flattened toolpath data) and
edit it through 2D-geometry mutators with cache-invariant refresh.
- GUI dispatcher runs capabilities during slicing under the GIL, turns plugin
errors into slicing errors, honors cancellation, and adds the plugin picker.
- Ships the InsetEverySlice sample plugin and binding/hook tests.

* fix: crash in Measure tool when a plain edge is the first selection
The SPHERE_2 gripper raycaster called get_feature_offset() on
.first.feature instead of .second.feature (copy-pasted from the SPHERE_1
block). Plain planar-border edges store no extra point, so the Edge
branch dereferenced an empty optional behind a release-stripped assert,
aborting on Flatpak and undefined behavior elsewhere.
Point the SPHERE_2 raycaster at .second.feature and fall the Edge branch
back to the edge midpoint.
Fixes#14018
{input_filename_base} is meant to be the saved project's file name. Before
#13753 a bug made it fall back to the first object's name when a project was
saved; #13753 fixed it to use the project name. Some users relied on the old
behavior to get the part name into their output file name and had no
placeholder to recover it ({model_name} is the 3mf designer metadata, blank
for plain STL imports).
Add {first_object_name} as a dedicated placeholder for the first printable
object on the current plate, populated in update_object_placeholders()
independently of {input_filename_base}.
Closes#14493
Selecting the prime tower and rotating it (PageUp/PageDown) crashed.
Selection::notify_instance_update() indexed m_model->objects with the
wipe tower's synthetic id (>= 1000), which is not a ModelObject index,
so the lookup returned garbage and dereferencing it segfaulted.
do_rotate/do_scale/do_mirror already skip the wipe tower in their own
loops but all call this shared helper, so scale and mirror hit the same
fault. Selection::drop() had the same latent bug via a direct index.
Guard both with the >= 1000 check already used throughout the file.
Fixes#14498
* Support accessing `coFloatsOrPercents` values in gcode template (OrcaSlicer/OrcaSlicer#14522)
* Vector option values are separated by comma
* Fix wrong cast used for checking nullability
Fix network plug-in install failing when the plug-in DLL is in use (#14373)
Switching or reinstalling the Bambu network plug-in from a running
OrcaSlicer failed with "The plug-in file may be in use". install_plugin()
deleted each existing file before extracting the new one, and on Windows a
currently-loaded DLL (BambuSource.dll, or the legacy networking library)
cannot be removed or overwritten in place, so the whole install aborted.
Rename an in-use file aside to "<name>.old" before writing the new one: the
running module keeps mapping the renamed file while the new version is
extracted, so the install succeeds without having to unload the plug-in
first. Stale ".old" files are cleaned up at the start of on_init_network(),
before the plug-in is (re)loaded, so they do not accumulate.
