* Add wxInspector dep
* Initial intergration of wxInspector
* docs: add wxInspector plugins design spec
Design spec for two wxInspector plugins (DPIAware + CustomWidgets) that expose
OrcaSlicer's custom control properties in the inspector property grid.
Covers: DPIAware scale-factor properties, Button, CheckBox, TextInput,
SwitchButton, ProgressBar, Label, and LabeledStaticBox.
* docs: add wxInspector plugins implementation plan
6-task plan covering: source changes to existing widget headers,
DPIAwarePlugin, CustomWidgetsPlugin, registration helper,
MainFrame/CMake wiring, and build verification.
* feat: add getters/setters for wxInspector plugin access
Add minimal public accessors to DPIAware (set_scale_factor,
set_prev_scale_factor, set_em_unit, force_rescale), Button
(GetStyle, GetType, IsSelected), CheckBox (IsHalfChecked),
TextInput (GetCornerRadius), and LabeledStaticBox
(GetCornerRadius, GetBorderWidth, GetBorderColor, GetScale).
* feat: add wxInspector plugin registration helper
Add RegisterOrcaInspectorPlugins() inline function that creates
and registers the DPIAwarePlugin and CustomWidgetsPlugin as
static instances (matching wxInspector's built-in pattern).
* feat: add DPIAware wxInspector plugin
Exposes DPI scaling properties (scale_factor, prev_scale_factor,
em_unit, normal_font, force_rescale) on DPIFrame and DPIDialog
widgets. Uses dynamic_cast for detection and a template helper
to capture the correct static type for lambda accessors.
* feat: add OrcaCustomWidgets wxInspector plugin
Exposes Orca-specific properties on 7 widget types:
- Button: Style, Type, Selected
- CheckBox: Half Checked
- TextInput: Label, Text Value, Corner Radius
- SwitchButton: Value
- ProgressBar: Proportion, Show Number
- Label: Is Hyperlink, Font Point Size
- LabeledStaticBox: Corner Radius, Border Width, Border Color, Scale
Each widget type uses dynamic_cast for safe detection.
* feat: wire wxInspector plugins into MainFrame and build
Call RegisterOrcaInspectorPlugins() in MainFrame constructor after
SetupInspectorAccelerator(). Add all 5 plugin source files to
SLIC3R_GUI_SOURCES in CMakeLists.txt.
* fix: move plugin registration to GUI_App::on_init_inner
Register plugins once in app init rather than in MainFrame
constructor, which may be recreated during the application
lifetime.
* fix: include plugin headers in Registration.hpp for complete types
Static locals require complete type. Include DPIAwarePlugin.hpp and
CustomWidgetsPlugin.hpp instead of forward-declaring. Also remove
unused include from MainFrame.cpp (registration moved to GUI_App).
* fix: qualify DPIFrame/DPIDialog with Slic3r::GUI namespace
* Make DPIDialog inspectable. For other dialogs, we will add them if necessary later.
* docs: add spec for moving wxInspectable into DPIAware template
Move wxInspector::wxInspectable base class from DPIDialog and MainFrame
into the common DPIAware<P> template, making all DPIAware widgets
automatically visible in the inspector tree.

* docs: add implementation plan for moving wxInspectable into DPIAware
Co-Authored-By: Claude <noreply@anthropic.com>
* docs: update spec/plan — move SetupInspectorAccelerator into DPIAware too
Co-Authored-By: Claude <noreply@anthropic.com>
* refactor: move wxInspectable and SetupInspectorAccelerator into DPIAware
DPIAware<P> now inherits wxInspector::wxInspectable and calls
SetupInspectorAccelerator in its constructor, making all DPIAware
widgets automatically appear in the inspector tree with the
Ctrl+Shift+I shortcut. DPIDialog now uses 'using' to inherit the
constructor. Remove redundant wxInspectable inheritance and
SetupInspectorAccelerator calls from DPIDialog and MainFrame.

Nightly Builds
🌙 Download the Latest Nightly Build
Explore the latest developments in OrcaSlicer with our nightly builds. Feedback on these versions is highly appreciated.
Belt Printer Builds
The nightly release ships two parallel builds: the standard build and a belt-printer build. Both are attached to the same release — tell them apart by the filename suffix:
- Standard — no suffix (e.g.
OrcaSlicer_Windows_Installer_x64_nightly.exe) - Belt —
_beltsuffix (e.g.OrcaSlicer_Windows_Installer_x64_nightly_belt.exe)
The _belt builds add experimental support for belt / conveyor (infinite-Z) printers, where the model is sliced against a tilted belt surface instead of a flat horizontal bed. They include ready-to-use belt printer profiles, the full belt slicing pipeline (mesh rotation and G-code transforms), belt-aware support generation, and a tilted-bed preview.
⚠️ Belt printer support is under active development and is not yet merged into
main— it currently ships only in these parallel_beltbuilds, produced from thebelt-printerbranch. See tracking PR #14394 and the original documentation in #12998.

Some Background
Open-source slicing has always been built on a tradition of collaboration and attribution. Slic3r, created by Alessandro Ranellucci and the RepRap community, laid the foundation. PrusaSlicer by Prusa Research built on Slic3r and acknowledged that heritage. Bambu Studio in turn forked from PrusaSlicer, and SuperSlicer by @supermerill extended PrusaSlicer with community-driven enhancements. Each project carried the work of its predecessors forward, crediting those who came before.
OrcaSlicer began in that same spirit, drawing from BambuStudio, PrusaSlicer, and ideas inspired by CuraSlicer and SuperSlicer. But it has since grown far beyond its origins. Through relentless innovation — introducing advanced calibration tools, precise wall and seam control, tree supports, adaptive slicing, and hundreds of other features — OrcaSlicer has become the most widely used and actively developed open-source slicer in the 3D printing community. Many of its innovations have been adopted by other slicers, making it a driving force for the entire industry.
The OrcaSlicer logo was designed by community member Justin Levine.
