 🌙 **[Download the Latest Nightly Build](https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/nightly-builds)**  
 Explore the latest developments in OrcaSlicer with our nightly builds. Feedback on these versions is highly appreciated.

+### Belt Printer Builds
+
+The [nightly release](https://github.com/OrcaSlicer/OrcaSlicer/releases/tag/nightly-builds) 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** — `_belt` suffix (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 `_belt` builds, produced from the [`belt-printer`](https://github.com/OrcaSlicer/OrcaSlicer/tree/belt-printer) branch. See tracking PR [#14394](https://github.com/OrcaSlicer/OrcaSlicer/pull/14394) and the original documentation in [#12998](https://github.com/OrcaSlicer/OrcaSlicer/pull/12998).

+# GLEW - The OpenGL Extension Wrangler Library
+
+The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems, including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.

+
+## Build
+
+It is highly recommended to build from a tgz or zip release snapshot.
+The code generation workflow is a complex brew of gnu make, perl and python, that works best on Linux or Mac.
+The code generation is known to work on Windows using [MSYS2](https://www.msys2.org/).
+For most end-users of GLEW the official releases are the best choice, with first class support.
+
+### Linux and Mac
+
+#### Using GNU Make
+
+GNU make is the primary build system for GLEW, historically.
+It includes targets for building the sources and headers, for maintenance purposes.
+
+##### Install build tools
+
+Debian/Ubuntu/Mint:    `$ sudo apt-get install build-essential libxmu-dev libxi-dev libgl-dev`
+
+RedHat/CentOS/Fedora:  `$ sudo yum install libXmu-devel libXi-devel libGL-devel`
+
+FreeBSD: `# pkg install xorg lang/gcc git cmake gmake bash python perl5`
+
+##### Build
+
+	$ make
+	$ sudo make install
+	$ make clean
+
+Targets:    `all, glew.lib (sub-targets: glew.lib.shared, glew.lib.static), glew.bin, clean, install, uninstall`
+
+Variables:  `SYSTEM=linux-clang, GLEW_DEST=/usr/local, STRIP=`
+
+_Note: you may need to call `make` in the  **auto** folder first_
+
+##### Linux EGL
+
+	$ sudo apt install libegl1-mesa-dev
+	$ make SYSTEM=linux-egl
+
+##### Linux mingw-w64
+
+	$ sudo apt install mingw-w64
+	$ make SYSTEM=linux-mingw32
+	$ make SYSTEM=linux-mingw64
+
+#### Using cmake
+
+The cmake build is mostly contributer maintained.
+Due to the multitude of use cases this is maintained on a _best effort_ basis.
+Pull requests are welcome.
+
+*CMake 2.8.12 or higher is required.*
+
+##### Install build tools

+## Code Generation
+
+A Unix or Mac environment is needed for building GLEW from scratch to
+include new extensions, or customize the code generation. The extension
+data is regenerated from the top level source directory with:
+
+	make extensions
+
+An alternative to generating the GLEW sources from scratch is to
+download a pre-generated (unsupported) snapshot:
+
+https://sourceforge.net/projects/glew/files/glew/snapshots/
+
+## Authors
+
+GLEW is currently maintained by [Nigel Stewart](https://github.com/nigels-com)
+with bug fixes, new OpenGL extension support and new releases.
+
+GLEW was developed by [Milan Ikits](http://www.cs.utah.edu/~ikits/)
+and [Marcelo Magallon](http://wwwvis.informatik.uni-stuttgart.de/~magallon/).
+Aaron Lefohn, Joe Kniss, and Chris Wyman were the first users and also
+assisted with the design and debugging process.
+
+The acronym GLEW originates from Aaron Lefohn.
+Pasi K&auml;rkk&auml;inen identified and fixed several problems with
+GLX and SDL.  Nate Robins created the `wglinfo` utility, to
+which modifications were made by Michael Wimmer.
+
+## Contributions
+
+GLEW welcomes community contributions.  Typically these are co-ordinated
+via [Issues](https://github.com/nigels-com/glew/issues) or
+[Pull Requests](https://github.com/nigels-com/glew/pulls) in the
+GitHub web interface.
+
+Be sure to mention platform and compiler toolchain details when filing
+a bug report.  The output of `glewinfo` can be quite useful for discussion
+also.
+
+Generally GLEW is usually released once a year, around the time of the Siggraph
+computer graphics conference.  If you're not using the current release
+version of GLEW, be sure to check if the issue or bug is fixed there.

-# Adaptive TPMS infill — High Level Design
-
-## Purpose and scope
-
-`tpms_adaptive` grades the sparse infill of the Gyroid, TPMS-D and TPMS-FK
-patterns inside the object: the cells grow continuously from the surface
-towards the center of the object. `distance_warp`, `smooth_blend` and
-`stepped_shells` follow the distance to the nearest surface, including the top
-and bottom, like concentric shells; `lobes` follows the whole 3D shape towards
-the center of each lobe of the object; `normal_z`, `normal_y` and `normal_x`
-follow each section of the object normal to that axis, so the grading does not
-change along the axis, as suits a profile extruded along it.
-`sparse_infill_density` is the density at the surface, `tpms_interior_density`
-the density at the center, and `tpms_adaptive_gradient` picks how the density
-goes from one to the other. Only internal sparse infill is graded; the Gyroid
-Z-buckling optimization does not apply to it.
-
-The design has two parts: a field built once per object, and a pattern made
-from it, warped around the center of each lobe of a body so that its cell size
-follows the field, or, in the modes following the distance to the surface,
-split into shells or blended between densities.
-
-## Radial field
-
-`TpmsRadialField` gives every point of an object the center of its lobe and a
-radial coordinate: 0 at the center, 1 at the surface along the ray from the
-center. `PrintObject::prepare_tpms_radial_fields()` builds it in
-`bridge_over_infill()`, next to the adaptive cubic octree, because the anchoring
-infill generated there has to match the printed infill. A field is built for
-every mode a region uses, and is shared by the regions using that mode: the
-field depends on the geometry only, the densities are applied per region in the
-fill. An object thinner than the grid cells has no body in the field; no field
-is kept then, and the infill falls back to the regular pattern. In the modes
-following the distance to the surface, the field also gives the depth of every
-point (see below).
-
-A regular 3D grid of cubic cells is rasterized from the `lslices` of the layers,
-so the field follows what is printed: negative volumes, the union of
-overlapping parts and holes are taken into account, and the mesh does not need
-to be closed. A padding node around the grid is always outside. The grid is
-capped at about a million nodes, with cells no smaller than 0.5 mm.
-
- Bodies are the connected inside nodes. Each is graded on its own, so separate
-  parts of one object each get their own sparse center.
- A body is split into lobes around the local maxima of the depth, by an exact
-  Euclidean distance transform (Felzenszwalb and Huttenlocher, one pass per
-  axis). Two maxima are in separate lobes when the depth along the segment
-  between them drops below 0.8 of the shallower one, like at the neck between
-  two united spheres; maxima shallower than 0.3 of the deepest one are ignored.
-  A maximum joins the first lobe whose first maximum it sees without a neck.
-  The lobes are made one at a time, the remaining maxima tested against the
-  first one in parallel, as a plate has a whole plane of them.
-  Where the depth ties along a line or a plane, as in a tall box, the lobe's
-  center is the node nearest to the middle of the tied nodes, so the center is
-  in the middle of the height and not a column.
- A point belongs to the lobe it is nearest to relative to their depths, so the
-  side between two lobes is nearer to the smaller one. Near that side, within a
-  tenth of that relative distance, the patterns of the lobes morph into each
-  other, so the lines stay continuous. Every lobe in that range takes part, up
-  to four, so the morph is also continuous where three or four lobes meet.
- The reach of a lobe is the distance from its center to the first exit along
-  24 x 48 latitude-longitude directions, smoothed twice over neighbouring
-  directions in log space. Towards a neighbouring lobe it stops at twice the
-  distance to the side between them, so that side is graded half way, as deep
-  as a neck is, rather than as sparse as the center or as dense as the surface.
-  Only the lobes whose centers are near enough to be nearer at the current
-  distance are compared along a ray, so many lobes, as in a perforated plate,
-  stay cheap.
-  The radial coordinate of a point is its distance to the center over the reach
-  in its direction. Behind a gap, as across the hole
-  of a ring, the radial coordinate is above 1 and the infill keeps the surface
-  density.
- Every outside node belongs to its nearest body, so points near a surface find
-  their body without a search. With a single body, all nodes belong to it.
-
-In the 2D modes, every plane of nodes normal to the axis is a field of its own:
-the distance transform skips the axis, bodies, lobes and the nearest body are
-found within the plane, and the reach is sampled on a circle of 48 directions.
-A point is looked up in the two planes around it, the weights of their lobes
-interpolated along the axis, so the grading does not step between planes; a
-plane without a body uses the nearest one that has one. The planes are a cell
-apart, not a layer: where the sections change abruptly, as at a step, the
-patterns of the two planes morph into each other over that cell.
-
-A distance to the nearest surface would be the obvious field, but no smooth map
-follows it. By the divergence theorem, the mean scale of a map over a body is
-fixed by its values on the surface: a map that keeps the full density along the
-whole surface, as the distance would ask under the top and bottom, has the mean
-density of the uniform infill, the sparser core being paid for by lines crowding
-along the walls. The layers of a plate at different depths would also need
-different line spacings in the same directions, which no continuous map allows
-without shearing across the plate. Following the distance needs changes of the
-topology of the lattice (see below). The radial coordinate instead grades what a
-single map can: towards one point.
-
-## Warped pattern
-
-The pattern is evaluated on warped coordinates:
-
-    TPMS(f_surface * m(t) * (p - center))
-
-where `m` scales the pattern around the center of the lobe: its frequency is
-`m + t * m'` along the ray and `m` across it. `m(t)` is the mean of the target
-scale over the ball of radius `t`, `3 / t^3 * integral of s^2 * target(s) ds`, so
-the mean of the three, and with it the density, follows the gradient. The cells
-are round at the center; near the surface they are flattened, with the lines
-running parallel to it. Beyond the surface the target is the surface scale, so
-the warp extends continuously outside.
-
-In the 2D modes only the coordinates within the plane are warped, and `m(t)` is
-the mean over the disc, `2 / t^2 * integral of s * target(s) ds`. Along the axis
-the pattern keeps the interior frequency: scaling it with `m` would shear the
-pattern by the distance along the axis times the gradient of `m`, without bound
-on a long object. The cells are round at the center and stretched along the
-axis near the surface. With Normal Z the layers are graded exactly, since
-the lines of a layer follow its in-plane frequencies; normal to X or Y, the
-layers near the sides are as dense as the larger of the two frequencies in the
-layer, which is the surface one.
-
-Evaluating a TPMS at a frequency that varies with the position without such a
-map distorts it wherever the frequency changes, because the phase also changes
-with the gradient of the frequency times the distance from the origin. Fitting a
-smooth map to a varying isotropic scale in the least-squares sense (a Poisson
-problem per axis) cannot grade strongly: its divergence is the target scale plus
-a harmonic function pinned by the surface, which keeps the scale in the core
-near two thirds of the surface one. Following a distance exactly needs the
-lattice to change its topology, by blending lattices of different densities or
-filling shells of equal distance with them, as the modes following the distance
-to the surface do.
-
-The target scale at depth `d = 1 - t`, with `S` the surface and `I` the interior
-frequency, both from each pattern's own density calibration:
-
-| Gradient    | Scale                  |
-|-------------|------------------------|
-| Linear      | `1 + (I / S - 1) * d`  |
-| Quadratic   | `1 + (I / S - 1) * d^2`|
-| Exponential | `(I / S)^d`            |
-
-With a denser surface, quadratic keeps the surface density deepest and
-exponential drops fastest. A denser interior works the same way.
-
-The zero level is extracted with marching squares like the regular TPMS-FK, on
-a sampling grid fixed in the fill frame like the optimized Gyroid, so that every
-region of a layer connects its lines the same way at the saddles of the pattern.
-Loops narrower than two lines (shorter than `2 * PI * spacing`) are dropped, as
-they would print as blobs. The fill works in a frame rotated by the infill
-angle, so the radial field is looked up at the point rotated back into the
-object frame, and the center rotated into the fill frame. Both use the middle of
-the layer.
-
-## Modes following the distance to the surface
-
-`distance_warp`, `smooth_blend` and `stepped_shells` grade by the distance to
-the nearest surface, including the top and bottom, as concentric shells do. The
-depth of a point is that distance over the distance of the deepest point of its
-body, from 0 at the surface to 1; the field keeps it for every node and
-interpolates it between them. A tall box so keeps its whole axis as sparse as
-its center, and a plate is graded through its thickness.
-
-No single smooth pattern follows that depth without distortion (see above), so
-the three modes trade differently:
-
- Distance warp keeps the lobes and the warp of Lobes, but its radial profile
-  comes from the depth. For every direction of a lobe, the mean depth over the
-  ball along the ray is sampled at 33 radii up to the reach, then smoothed over
-  the neighbouring directions like the reach. The radial coordinate is the one
-  of the linear profile with the same mean depth, `t = 4/3 * (1 - mean depth)`,
-  so with a linear gradient the mean cell size follows the depth exactly, and
-  with the others approximately. In a sphere or a cube, where the depth falls
-  linearly along every ray, it is Lobes. Elsewhere the profile changes with the
-  direction, and the warp shears where neighbouring directions differ, as in
-  plates and long bodies; right under the top of a long body the cells are
-  sparser within the layer, the warp moving their density into the height.
-  The profiles are smoothed over the directions like the reach, as sharper
-  ones shear the pattern across the layer, which adds lines. A long body is so
-  graded partly along its length, between Lobes and the distance.
- Smooth blend evaluates the regular patterns of the two levels around the
-  target of every point and blends them by a smoothstep over the whole gap
-  between the levels, here at most 2.5 times apart. The density follows the
-  depth without steps, but where two lattices blend, part of their lines run
-  along the blend, so fewer levels print fewer extra lines. From 25% to 5%,
-  three levels print about 0.45 of the uniform infill in a deep core whose
-  levels alone would print 0.3; levels 1.5 times apart print 0.6 to 0.7, and a
-  single blend from the surface to the interior 0.6.
- Stepped shells split each region of a layer into shells and fill every shell
-  with the regular pattern at its density. The densities are levels from the
-  surface to the interior density at most 1.5 times apart, five from 25% to 5%,
-  and a point takes the level nearest to its target on that geometric scale.
-  The shells are traced by marching squares of the continuous level over the
-  layer on a 0.5 mm grid fixed in the object, so every region of a layer gets
-  the same shells, and clipped to the region. Each shell is shrunk by half a
-  line, like a filled region, and its regular filler connects its lines along
-  that boundary, so the connections of two neighbouring shells lie side by side
-  instead of on top of each other. The pattern is never
-  distorted, but its lines end at every shell, and thin parts get thin shells.
-  The connections add lines: in the core of a 60 mm cube, about a third more
-  than the target.
-
-Stepped shells and Smooth blend need neither lobes nor reaches, which are not
-built for them.
-
-## Constraints
-
- With `tpms_adaptive` disabled, or for other patterns, the fill parameters are reset
-  to their defaults, so they neither change the infill nor split fill batches.
- `Layer::get_sparse_infill_max_void_area()` uses the sparser of the two
-  densities, as the voids at the center are that large.
- At a sparse infill density of 100% the sparse infill is turned into solid
-  infill, so there is nothing to grade: the options are hidden and no field is
-  built.
- The adaptive options invalidate `posPrepareInfill`, which rebuilds the field
-  and the anchoring infill.
- An elongated body without a neck has one center, so its far ends are graded
-  as the outer part of the body, and the warp shears where the reach changes
-  quickly with the direction. A concave body, like an L, may be split into lobes
-  where its maxima cannot see each other in a straight line.
- Across a ray, the scale is the mean of the gradient from the center, so the
-  layers right under the top and above the bottom are sparser than the surface
-  density in their middle, and a plate is graded from its middle outwards rather
-  than through its thickness.

-# Center of mass markers — High Level Design
-
-## Purpose and scope
-
-The "Center of mass" item of the canvas toolbar menu, in the bottom left corner of the 3D view, marks
-where the mass of the plate, of each object instance and of each body of an assembly is centered,
-in Prepare and in Preview. It helps judge how parts will rest on the plate, for instance whether a
-tall or leaning part could tip. It is a view setting: it changes nothing in the model, the slice or
-the project file, and it does not reach plate thumbnails. The choice is kept in the app config as
-`show_center_of_mass`, off by default. The assembly view and the Design tab have no markers.
-
-Three kinds of marker share one shape, a sphere whose octants alternate between two colors:
-
- each plate, black and white, for everything on it;
- each object instance, light blue and white;
- each body of an assembly, red and yellow;
- in Preview, the supports and raft of each object instance, green and black.
-
-A click on a marker opens a box beside it with the weight and volume of what it stands for, where its
-center lies in that thing's bounding box and the size of the box, and its moments of inertia about
-axes through the center parallel to x, y and z.
-
-An assembly is an object of several parts or with negative volumes. Its bodies are the connected
-solids its parts make once united, the bodies the separated infills option centers its infill on
-(see separated-infills.md): parts that overlap or touch are one body, parts apart are separate
-bodies. An object of one body, and every object of a single part, has no body markers, as its object
-marker says it all.
-
-Mass is volume times density, the `filament_density` of the filament that prints it, or 1.245 g/cm³
-(`DEFAULT_FILAMENT_DENSITY`) for a filament without one. Prepare has the model only, so it takes each
-part as a solid of the density of its filament, the part's own or else its object's. It reads each
-filament's density from the filament's selected preset, edits not yet saved included, as slicing does:
-the plater's own config holds the values of the filament edited last only. Preview has
-what will be printed, so its markers come from the toolpaths, whose mass depends on walls, infill
-and flow as well. There the solid markers are for what is printed up to the top layer the layer
-slider shows: for the plate with brim, raft and supports, where the weight rests at that point of
-the print; for an object or a body, its own extrusions. Each has a faded twin for the same at the
-end of the print, so the slider shows the weight moving toward where it ends, and at the top layer
-the two meet. In Prepare the plate has the model alone, as brim, raft and supports exist only once
-sliced.
-
-## Prepare: from the meshes
-
-An object of one part takes the mass properties of its mesh at unit density, times its density, from
-`its_mass_properties()`, which handles a mesh in a single pass. Each triangle and a fixed vertex of
-the mesh span a tetrahedron whose signed volume is `V = a · (b × c) / 6`, with `a`, `b`, `c` taken
-relative to that vertex. By the divergence theorem these volumes add up to the volume of a closed
-mesh, their volume-weighted centroids to its center of mass, and their second moments
-`V (a aᵀ + b bᵀ + c cᵀ + s sᵀ) / 20`, with `s = a + b + c`, to its own. Shells facing inward, such as
-a cavity, subtract themselves, and flipping every triangle changes nothing. The sums are kept in
-double precision and relative to a vertex of the mesh rather than the origin, which keeps them exact
-for meshes far from it. The result keeps the spread of the mass about its center,
-`(x - c)(x - c)ᵀ` averaged over the mass, from which the moments of inertia follow.
-
-The CGAL routines that look alike do not compute this. `CGAL::centroid` weighs tetrahedra by their
-unsigned volume, so it fails on cavities and on any shell that is not star-shaped from the fan's
-apex; over triangles it returns the centroid of the surface, and over points the average of the
-vertices, which depends on the tessellation. `CGAL::barycenter` with the signed volumes as weights
-gives the same answer, but only after copying every tetrahedron into a vector of weighted points,
-and takes two and a half times as long.
-
-A mesh's result is in its own coordinates. Each `GLVolume` maps it to the world with its world
-matrix `M`, and weighs it by the volume times the absolute determinant of that matrix: a center of
-mass moves with any affine map, and the spread becomes `L S Lᵀ` for the linear part `L` of `M`, so no
-mesh is ever transformed. The `GLVolume`'s matrices, rather than the
-model's, let the markers follow an object while it is dragged, before the model is updated. Results
-are cached by `ModelVolume` id; a `ModelVolume` takes a new id whenever its mesh changes, which is
-the rule `reload_scene()` relies on to rebuild a `GLVolume`'s geometry, so a cached result never
-outlives its mesh.
-
-An assembly's parts overlap or touch, which the mesh formula would count twice, so `solid_bodies()`
-slices them instead, in the object's coordinates. It cuts the height into 500 slabs, 100 while a part
-is dragged, slices every part and negative volume at the middle of each slab, unites the parts and
-cuts the negative volumes away, and links the islands of neighboring slabs that overlap into bodies
-with `connected_bodies()`. Each island adds a prism of the slab's thickness at the density: its
-area, and its first and second moments of area, from the same sums over the outline as the area,
-with the slab's height for z. Where parts of different densities overlap, the later volume of the object counts, as
-slicing clips every part by the parts after it; each part then weighs the region it prints, which is
-credited to the island holding it. Each body also keeps the convex hull of its islands and the height
-they span, whose corners, once transformed, give its bounding box, tight while the instance turns
-about z only. The object is the sum of its bodies, its box that of its parts, as the object's size
-shows it, and each plate the sum of the object instances `PartPlateList::find_instance()` puts on it,
-so that an instance on no plate counts in none. The bodies are cached by `ModelObject` id with the volumes, types, densities and
-transformations they were sliced from.
-
-## Preview: from the toolpaths
-
-`GCodeProcessor` sums the masses while it processes the G-code, in the same pass that builds the
-moves, and leaves them in `GCodeProcessorResult`; `GCodeViewer` keeps a copy of them when it loads a
-result. Nothing is stored per move.
-
-Each extrusion weighs the volume of filament its E extrudes times the density of the filament that
-extrudes it, so a print of several materials weighs each as it is. Flow ratio, line widths, ironing
-and purging into infill all count
-as printed. Its mass spreads evenly along the segment the bead's center runs, half the layer height
-below the nozzle, in the frame of the stored moves: plate offset added, Z offset removed. Such a
-segment from `a` to `b` adds `m (a + b) / 2` to the moments and `m (a² + a b + b²) / 3` to the second
-moments along each axis, and its box widened by half the bead's height to the bounding box; not by
-half its width, which the processor only estimates, so that a box runs along the walls' center lines. Arcs are already split into segments by the processor. Walls, infill, top and bottom surfaces, ironing
-and gap fill make the parts. The brim and the support roles, the raft among them, count only in what
-the plate prints. The skirt, the prime tower and custom G-code count nowhere.
-
-The plate takes every extrusion, so it needs nothing more. The objects and bodies need the sliced
-objects, which the G-code does not describe, so the G-code export hands the processor a locator
-built from the `Print`; G-code opened from a file, or from a project sliced earlier, has no `Print`
-behind it, and so shows the plate alone. Object labels would not do: profiles turn the four kinds
-Orca writes on and off in every combination, and none of them tells the bodies apart.
-
-The locator numbers the object instances and, for each assembly, the bodies of every instance. It
-takes the bodies `PrintObject::prepare_infill()` found for separated infills, or, when that option
-did not need them, links the islands (`Layer::lslices`) of neighboring layers into bodies with the
-same `connected_bodies()`. For each extrusion of a part, it finds the first layer printed at or above
-its height, as spiral vase rises through each layer, and the island holding it with an
-`IslandLocator`, the one `solid_bodies()` credits its regions with: by the island's box, widened by
-1 mm for walls reaching past it, with a polygon test only where boxes overlap, and the nearest
-outline where none holds the point. The boxes of one layer's islands say nothing of the other
-instances, so an instance whose widened box reaches another's, as copies placed side by side do,
-tests the outlines alone, and outside them the nearest outline of all such instances wins. The island
-gives both the instance and the body. The island found last is tried first, as extrusions mostly follow each other on one
-island. Brim, raft and supports lie outside the islands. The brim counts in the plate only; a support
-or raft extrusion goes to the instance whose footprint, the box of its widened islands, holds it, the
-one whose center is nearest among several, or else the nearest footprint, as supports stand below and
-around their object.
-
-Each mass holds, for each layer id, the running total of what is printed up to that layer, the last
-of which is the faded marker's, so the solid marker for any slider position is a single lookup. The layer ids are those
-the moves carry, which are also the layers of libvgcode and of the slider; in a print by object they
-follow the order of printing, so the solid markers show the objects printed so far as they are.
-
-## Drawing
-
-`smooth_sphere()` with a resolution divisible by four leaves every triangle within one octant, so it
-splits into two models drawn with the `gouraud_light` shader in each kind's two colors. The radius is
-9 pixels for the plate, 7 for the objects, 6 for the supports and 5 for the bodies, scaled like the canvas toolbar for the
-display's DPI and kept constant on screen through the camera's inverse zoom. They are drawn in that
-order, so that markers at one place show as rings. The faded markers are the same spheres at 40%
-opacity, drawn before all the solid ones, which show over them where both meet.
-
-The centers usually lie inside the objects, so the markers are drawn without the depth test and show
-through the objects and anything in front of them. Back face culling keeps the far half of a sphere
-from covering the near one. They are drawn after the ambient occlusion pass, which would otherwise
-darken them as the surface behind them, and before FXAA, which smooths their edges.
-
-The markers are part of the cached scene, so toggling them, or changing a filament's density while
-they are shown, marks the scene dirty, and moving the layer slider redraws the scene with the solid
-markers where they belong. In Prepare they are hidden while any gizmo other than Move, Rotate, Scale
-and Lay on face is open, since the others work on the surface a marker would cover, and a hidden
-object has no markers.
-
-## Details
-
-The markers drawn last are kept, and a left click is tested against them before it selects: each
-center and a point a radius to its right are projected to the screen, and the click hits a marker
-within that distance. The solid markers are tested before the faded ones and the smaller kinds
-before the larger, the order in which they cover each other. A hit opens the details of that marker
-and keeps the click from changing the selection; a click anywhere else closes them. The box is an
-ImGui window beside the marker, redrawn with the overlay from the markers of the last scene, so it
-follows a dragged object, and in Preview the layer slider. It closes when its marker is gone, or when
-the number of markers of its kind changes, as then it may stand for something else.
-
-Its title says what the marker stands for: the plate, an object, an assembly or a part, the body of
-an assembly. The G-code export lists the object instances for the processor, marking assemblies, as
-it hands it the locator.
-
-Each marker carries its sums: mass, volume, first moments and the second moments about the origin
-along each axis, `Σ m x²`, `Σ m y²` and `Σ m z²`, which add up from parts to objects to plates. The
-moment of inertia about the axis through the center parallel to x is then
-`m (σy² + σz²)`, with `σ² = Σ m x² / m - c²` along each axis, and likewise for y and z. Masses are
-kept in mg, volume times density in g/cm³, and shown in g, volumes in cm³ and moments of inertia in
-g·mm². In Preview the box tells the finished print from what is printed up to the layer shown, the
-two weighing differently, and both are placed in the bounding box of everything the marker holds
-by the end.

+# Multi-extruder and multi-AMS device control
+
+`DeviceManager`/`MachineObject` model the toolheads, AMS units, and filament slots of a connected
+printer and drive the device-control UI from that model. The model represents the counts as
+device-reported runtime values rather than compile-time caps, so a printer with an arbitrary number
+of toolheads, several AMS units, and a non-uniform number of slots per unit is handled by the same
+code paths. The printer agent is responsible for translating its printer's state into the shared
+JSON dialect this model consumes; the agent boundary is described in
+[printer-agent.md](printer-agent.md), and this document describes the dialect and the model.
+
+## Model layout
+
+`MachineObject` owns the device subsystems that this document covers:
+
+- `DevExtderSystem` — the toolheads (extruders) and their per-toolhead filament/temperature state.
+- `DevFilaSystem` — the AMS units (`DevAms`) and their trays (`DevAmsTray`).
+- `DevNozzleSystem` — the nozzles and, on rack printers, `DevNozzleRack`.
+- `DevFilaSwitch` — a filament switch that can feed several AMS units to more than one extruder.
+
+Each subsystem exposes its own count — `DevExtderSystem::GetTotalExtderCount()`,
+`DevFilaSystem::GetAmsCount()`, `DevAms::GetSlotCount()` — and the rest of the application derives
+its layout from those values rather than from fixed assumptions.
+
+## Wire dialect
+
+The dialect is the Bambu-shaped JSON that `DeviceManager` and `MachineObject` already consume. An
+agent whose printer speaks something else is expected to translate into it; the agent is not free
+to invent a new shape. Two representations coexist for extruders, and one for AMS/slots.
+
+### Extruders
+
+The generic representation is `print.device.extruder`, parsed by
+`ExtderSystemParser::ParseV2_0` (`DevExtruderSystem.cpp`). It has a packed `state` integer and an
+`info` array with one object per toolhead:
+
+```text
+device.extruder.state           packed integer
+  bits  0..3   total extruder count
+  bits  4..7   current extruder id
+  bits  8..11  target extruder id
+  bits 12..14  switch state
+  bits 15..18  currently loading extruder id
+  bit   19     busy for loading
+
+device.extruder.info[]          one entry per toolhead
+  id          extruder id
+  filam_bak   array of backup-group bits
+  info        bit 1 has filament, bit 2 buffer has filament, bit 3 nozzle present
+  temp        bits 0..15 current temperature, bits 16..31 target temperature
+  spre        slot_id bits 0..7, ams_id bits 8..15 (previous)
+  snow        same packing (current)
+  star        same packing (target)
+  stat        bit 0..15 AMS status, bits 16..31 RFID status
+  hnow        current nozzle id
+```
+
+The legacy single/dual representation is the pair of scalar fields `nozzle_temper` /
+`nozzle_target_temper`, plus the `print.ams.tray_tar` / `tray_now` tray pointer, parsed by
+`ExtderSystemParser::ParseV1_0`. That parser is a fallback and only fills the main extruder when the
+reported toolhead count is one.
+
+Physical extruder ids are fixed (`MAIN_EXTRUDER_ID = 0`, `DEPUTY_EXTRUDER_ID = 1`). Bambu printers
+present the two toolheads as a left/right pair and invert the physical-to-logical mapping; generic
+printers use the toolhead id itself as the logical id. `DevNozzle::GetLogicExtruderId()` /
+`GetExtruderId()` centralise that distinction.
+
+### AMS units and slots
+
+AMS units arrive as `print.ams.ams[]` and are parsed by `DevFilaSystemParser::ParseV1_0`. Each unit
+carries an `id` and an `info` bitfield:
+
+```text
+info bits  0..3    type: 0 dummy, 1 AMS, 2 AMS-Lite, 3 N3F, 4 N3S, 5 AMS-Lite-mixed (N9)
+info bits  8..11   bound extruder id (0xE marks a switch-bound unit)
+info bits 24..27   switch inlet when the unit is switch-bound
+```
+
+`DevAmsType` (`DevDefs.h`) enumerates the resulting unit kinds: `EXT_SPOOL`, `AMS`, `AMS_LITE`,
+`N3F`, `N3S`, and the `AMS_LITE_MIXED` N9 variant. `AMS_LITE_MIXED` reports itself as `AMS_LITE` to
+generic callers; code that needs the distinction uses `IsAmsLiteMixed()`.
+
+A unit whose bound-extruder nibble is `0xE` is switch-bound: it is kept only when a `DevFilaSwitch`
+is installed, in which case its extruder id is pinned to the main extruder and its binding set
+becomes `{0, 1}`; otherwise the unit is dropped from the AMS list.
+
+Each unit owns a map of `DevAmsTray` keyed by the tray id from the payload. The slot count is a
+property of the unit kind and the reported trays:
+
+- `AMS`, `AMS_LITE`, and `N3F` report four slots on Bambu printers, matching the firmware contract;
+- `N3S` reports one slot;
+- `EXT_SPOOL` and any non-Bambu unit report the number of trays actually present.
+
+The tray ids are the payload's slot indices; they are expected to be unique, 0-based, and contiguous
+within a unit, because the generic tray-index mapping below is cumulative.
+
+Bulk/extended spools are carried by `print.vir_slot`, which `DeviceManager` parses into
+`MachineObject::vt_slot`. Two ids are fixed: `VIRTUAL_TRAY_MAIN_ID = 255` (extruder 0) and
+`VIRTUAL_TRAY_DEPUTY_ID = 254` (extruder 1); the id convention is `vt_id = 255 - extruder_id`, so
+further extruders use 253, 252, … . The `vir_slot` parser recognises the 255/254 pair; the agent
+filament descriptor path `DevFilaSystemParser::ParseAgentFilament` is the entry that stores a fuller
+descending set in `vt_slot`.
+
+## Mapping
+
+Several subsystems relate AMS units, trays, and extruders, and more than one place derives a tray
+index. The Bambu mapping path (`DevMappingUtil`) computes `ams_id * 4 + slot_id` and knows only the
+Bambu unit kinds; `DevFilaSystem` provides the device model's own mapping below. The two agree for
+Bambu units and diverge for a non-Bambu unit whose slot count is not four.
+
+### AMS id to extruder id
+
+`DevFilaSystem::GetExtruderIdByAmsId()` resolves an AMS id to the extruder it feeds:
+
+- an AMS unit returns its bound extruder (`DevAms::GetExtruderId()`);
+- a virtual tray returns `VIRTUAL_TRAY_MAIN_ID - vt_id`;
+- Bambu's virtual AMS ids map to the main/deputy extruder.
+
+A unit may be bound to more than one extruder when a `DevFilaSwitch` feeds it; the binding set
+(`DevAms::m_binded_extruder_set`) and switch inlet are read by switch-aware code while the
+single-extruder id stays pinned for legacy callers.
+
+### Tray index
+
+`DevFilaSystem::GetTrayIndexMap()` maps a global tray index to an `(ams_id, slot_id)` pair and is
+used for backup-slot translation, calibration addressing, and the mapping popups.
+
+- Bambu AMS: `ams_id * 4 + slot_id`; N3S: the AMS id; AMS-Lite-mixed (N9): `24 + slot_id`.
+- Generic (non-Bambu): a running lane index — the count of trays in preceding units plus the slot
+  id. This depends on each unit's tray ids being 0-based and contiguous.
+
+### Virtual-slot recognition
+
+`devPrinterUtil::IsVirtualSlot()` decides whether an id denotes a virtual tray. On Bambu printers it
+is the fixed pair `{255, 254}`. On generic printers it is the descending range
+`[255 - count + 1, 255]`, where `count` is the selected printer preset's extruder count. The preset
+is expected to match the connected device; when the two disagree the virtual range is wrong, which
+is why a mismatch is reported rather than silently accepted.
+
+## Device-control UI
+
+The device-control widgets follow the same device-reported counts.
+
+- `AMSModel` (`AMSItem.hpp`) mirrors `DevAmsType` numerically: `EXT_AMS`, `GENERIC_AMS`, `AMS_LITE`,
+  `N3F_AMS`, `N3S_AMS`. A plain `AMS` maps to `GENERIC_AMS`.
+- On non-Bambu printers `use_generic_ams_layout()` routes `GENERIC_AMS` units through a variable-lane
+  rendering that draws one lane per reported tray; Bambu keeps its fixed four-slot rendering.
+- `AMSControl` picks its layout by toolhead count, not vendor: `CreateAmsSingleNozzle` for one
+  toolhead, `CreateAmsDoubleNozzle` for two, and `CreateAmsMultiNozzle` (one preview and one AMS
+  simplebook per toolhead) for three or more. A two-toolhead generic printer therefore keeps the
+  legacy left/right presentation; that is deliberate.
+- The status panel's `ExtruderImage` renders one per-toolhead state per nozzle and is resized to
+  `GetTotalExtderCount()`. Non-Bambu printers choose the active toolhead through
+  `m_generic_nozzle_selector` (shown when more than one toolhead exists); Bambu keeps its left/right
+  `m_nozzle_btn_panel`. Nozzle temperature controls are created on demand per toolhead.
+
+## Constraints
+
+- **Single dialect.** The agent translates its protocol into this JSON; the model does not learn
+  vendor protocols. Extending the model with a new unit kind or field means extending the dialect.
+- **Agent-produced counts.** Toolhead, AMS, and slot counts come from the device payload. Nothing
+  caps them at two toolheads or four slots except the Bambu contract described above.
+- **Extruder dialect invariants.** `device.extruder.state`'s count field must equal the length of
+  `info[]`, and `info[]` must be ordered by extruder id with `id` equal to the array index: the
+  parser places toolheads by array position while `GetExtderById()` indexes by id.
+- **One filament road per toolhead.** Each toolhead renders a single AMS filament road rather than an
+  independent per-toolhead road state. A generic scaffold that allowed the latter was removed as
+  unused; the one-extruder-per-toolhead road is the intended model.
+- **Preset/device agreement.** The generic layout and virtual-slot range derive their count from the
+  selected printer preset. A printer preset must therefore declare the same number of
+  `nozzle_diameter` entries as the device has toolheads. A mismatch is surfaced only as a log warning
+  (`StatusPanel::check_extruder_count_mismatch()`), deliberately log-only, because the sidebar and
+  extruder logic would otherwise silently disagree.
+- **Bambu compatibility.** Bambu-specific presentation (left/right pair, fixed 4-slot units, fixed
+  virtual ids, physical/logical inversion) is preserved behind the vendor check. Generic paths do
+  not alter it.
+- **Tray-index invariant.** The generic tray-index map is cumulative, so payload tray ids must be
+  unique, 0-based, and contiguous per unit. A malformed id is a producer error.
+- **Protocol markers.** The dialect has no neutral equivalent for some Bambu state, so agents that
+  lack it send empty `print.cfg`, `print.fun`, `print.aux`, and `print.stat`. Their presence selects
+  the new-protocol parse path; they are compatibility markers, not feature switches.

-# Separated infills — High Level Design
-
-## Purpose and scope
-
-An object's infill patterns are laid out from one reference point, the center
-of the object. When an object groups several parts that do not touch, every
-part cuts the same object-wide pattern at a different place, so equal parts get
-different infill. `separated_infills` lays the infill of every connected body
-out from the center of that body instead, as if the body were sliced on its own.
-
-The option covers sparse infill, internal solid infill and bridges. Top and
-bottom surfaces are left to `center_of_surface_pattern`, which centers the
-Archimedean Chords and Octagram Spiral surface patterns. The option is off by
-default; with it off, or for an object made of a single body, no fill changes.
-Adaptive Cubic and Support Cubic do not depend on the option: they always fill
-each body on its own (see Octree infill).
-
-## Bodies
-
-`PrintObject::prepare_infill()` groups the islands of every layer (`lslices`)
-into 3D connected bodies with `connected_bodies()` before bridges are detected,
-so bridge anchors and printed infill share one origin. Islands on adjacent layers belong to one body
-when their slices overlap. Parts that touch or overlap form one body. Separate
-parts, disconnected islands of one mesh, and interleaved parts that never touch,
-such as chain links, each form their own. Every island stores the index of its
-body in `Layer::lslices_separated_component_ids`, and
-`PrintObject::separated_body_bboxes()` holds the bounding box of each body over
-all its layers.
-
-The pass runs when a region uses separated infills, per-model surface centering
-or an octree infill pattern. It is skipped when the object has one model part
-that cannot be split, since a single body already shares the object center.
-
-## Centering a fill
-
-`infill_body()` matches each fill region to the island it overlaps most, among
-the islands whose bounding boxes overlap it, and the filler takes the bounding
-box of that island's body instead of the object's. The box covers every layer
-of the body, which is the box the body gets when sliced alone, so patterns that
-depend on its extent as well as its center come out the same too. Bridge
-anchoring (`Layer::generate_sparse_infill_polylines_for_anchoring()`) makes the
-same choice, so the anchors match the printed infill.
-
-The patterns follow the body's box in one of two ways:
-
- Rectilinear and its variants, Line, Grid, Triangles, Tri-hexagon, Cubic,
-  Quarter Cubic, Lateral Lattice, Lateral Honeycomb and the plane-path patterns
-  (Hilbert Curve, Archimedean Chords, Octagram Spiral) are laid out from the
-  box: they phase their lines through its center, and Hilbert Curve and the Zig
-  Zag links start from its corner. `Fill::extended_object_bounding_box()`
-  extends the box about its center, so it also serves a box that is not
-  centered on the origin.
- Honeycomb, 3D Honeycomb, Cross Hatch, Gyroid, TPMS-D and TPMS-FK are laid out
-  from the coordinate origin, which is the object center. They return true from
-  `Fill::aligned_to_origin()`, and `Fill::fill_surface()` moves each region so
-  that the box center lands on the origin, fills it, and moves the paths back.
-  With the default box the center is the origin, so nothing moves.
-
-`is_separable_infill_pattern()` lists these patterns. The settings show the
-option only when the sparse infill pattern is one of them.
-
-## Octree infill
-
-Adaptive Cubic and Support Cubic take their lines from an octree, laid out from
-the center of the mesh it is built from and refined near its surfaces. An
-octree of the whole object would lay every part out from the object's center
-and refine it near the other parts, so these patterns
-(`is_octree_infill_pattern()`) always fill each body on its own, and the
-settings hide the option for them.
-
-For an object of several bodies, `PrintObject::prepare_adaptive_infill_data()`
-builds one octree per body (`FillAdaptive::Octrees`) from the triangles of that
-body only, which is the octree the body gets when sliced alone. Each connected
-component of the mesh goes to the body that most of a few sampled triangles lie
-on. A sample is taken a layer height inside the solid, behind the triangle, and
-looked up in the islands of the nearest layer. Each internal bridge surface goes
-to the body of its island. The fill takes the octree of the region's body, from
-the same `infill_body()`. The octree of the whole object is built only for an
-object of a single body, or when some body received no triangles, which then
-uses it.
-
-The line spacing of an octree comes from the density, line width and multiline
-count of a region, so a modifier or a part with its own density needs octrees of
-its own. `adaptive_fill_line_spacing()` gives the spacing of each region, and
-`FillAdaptive::RegionOctrees` holds one set of octrees per distinct spacing,
-shared by the regions that have it. A set is built only for the bodies its
-regions fill. The fill takes the set of its region, then the octree of its body.
-
-## Patterns left out
-
-Lightning grows its trees over the whole object, so moving a reference point
-cannot center it on one body. Concentric and Spiral Inset follow the outline of
-each region and need no centering.
-
-Solid infill at full density spaces its lines over the extent of each region,
-so it is already independent of the other bodies. Only bridges, which keep
-their line spacing, and the plane-path solid patterns depend on the center.
