Adds the approved design for a `file.open` JSON-RPC method that loads
files into a running OrcaSlicer via Plater::load_files (synchronous, GUI
thread). Dialog-driving approaches deferred.
The on-screen window capture is composited from the desktop framebuffer, so it
already includes the GL 3D viewport as currently shown (model in the editor,
toolpaths in Preview). The offscreen render_thumbnail path only ever drew the
model GLVolumeCollection — never the gcode toolpaths — and produced a blank image
after slicing because the app switches to the Preview panel. Rather than maintain a
second, more limited capture method, remove it entirely.
Removes the JSON-RPC method, IUiBackend/WxUiBackend implementation, dispatcher
route + capability entry, the now-dead opt_int/thumbnail_to_wximage helpers and
ThumbnailData include, the mock override + unit test, and the Python
screenshot_3d client method. Docs updated accordingly.
Blitting from the MainFrame's own wxClientDC clips out child HWNDs, so all of
OrcaSlicer's custom child-window controls (sidebar buttons/combos/panels) and the
GL canvas came back as uninitialized black bitmap memory. Read the window's
on-screen rectangle from the DWM-composited desktop via wxScreenDC instead, which
includes every child window, the OpenGL surface, and ImGui overlays.
Document the visible/unobscured requirement and the HiDPI logical-vs-physical
pixel caveat; clarify how screenshot.viewport3d differs and why it stays.
Design for an opt-in localhost JSON-RPC server that lets an external script/AI agent drive and observe the OrcaSlicer GUI (wxWidgets + 3D viewport + ImGui) via wxUIActionSimulator.
* Preserve support base outline/fill order
Honor no_sort when emitting support toolpaths to keep outline-first order.
Group tree support base paths (including lightning) into per-area no_sort collections to prevent interleaving across islands.
Keep lightning layer lookup side-effect free.
* Tag Orca specific changes
Tag Orca specific changes vs. Bambu using the comment //ORCA: . This helps when reviewing merge commits from upstream Bambu so we don't end up causing regressions when pulling in commits from upstream
* Fix: Disable redundant toolchange retraction for Elegoo Centauri Carbon
Sets `retract_length_toolchange` to 0 in the Elegoo Centauri Carbon (ECC) machine profile.
This resolves an issue where a massive filament blob would form on the prime tower immediately after resuming a manual filament change (M600). The blob was caused by a conflict between OrcaSlicer's default toolchange logic and Elegoo's hardcoded firmware behavior:
- Elegoo's firmware (specifically the `cmd_PAUSE` and `cmd_RESUME` sequences) completely takes over pressure management during an M600. It performs its own initial 2mm retraction, a 120mm purge, and a silicone brush wipe, returning the print head to the prime tower perfectly primed.
- Previously, Slicer was unaware of the firmware's priming and would issue a redundant 2mm un-retract (`G1 E2`) upon resume. Forcing 2mm of filament out of an already-full nozzle created the blob.
By disabling the toolchange retraction (`0`), Slicer correctly hands off filament pressure management during an M600 entirely to the Elegoo firmware, preventing double-retractions and eliminating the blob.
