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).

"""Belt temperature-tower asset generator (discrete-provini design).
A vertical temperature tower cannot be sliced on a belt printer, so lay a row of
DISCRETE provini (one per temperature) along the belt (designed Y) with a fixed
surface gap. Each provino is the chevron+arc unit (belt_temp_provino_unit.stl,
keel-first); its temperature is ENGRAVED upright into the 50 mm face — a raised
number would be an unsupported overhang on the belt. The C++ calib_temp belt branch
(Plater.cpp) injects one M104 per zone 70 layers INTO provino i:
print_z[i] = i * PITCH * cos(theta) + 70 * layer_height (theta = 45)
inside the body, not in the empty inter-provino gap (which has no sliced layers for
the event to attach to). PITCH below is the shared geometry contract with that code —
keep them in sync.
Generates one STL per filament temp range used by Temp_Calibration_Dlg.

//
// Consequences that drive everything in this file:
//
// * A horizontal slicing layer touches the belt only along a narrow strip at
// its leading edge, `layer_height / shear` wide (~0.2 mm at 45 degrees).
// The object's belt footprint - its bottom face - is therefore spread over
// every layer, not contained in layer 0.
// * Distances measured in slicing XY are NOT on-belt distances: moving `du`
// along the shear axis travels `du / cos(tilt)` across the belt. So brim
// offsets have to be taken in a "flattened" space where the shear axis is
// stretched by `1 / cos(tilt)`, then mapped back.
// * Brim ahead of the part (downhill) lies at slicing Z BELOW the object's
// first layer, because the object's layer 0 is precisely its leading
// contact with the belt.

//
// The pre-slice pipeline applied in PrintObjectSlice.cpp is:
// trafo_out = z_shift * rotation * trafo_in
//
// Rotation is the sole mesh-side belt transform; shear & scale are applied
// to the g-code instead (see MachineFrameTransform). This class provides the
// building blocks so every call site uses the same implementation. z_shift is
// object-dependent (computed from mesh vertex bounds) and is NOT included in
// build_forward_transform(). The machine-frame shear/scale is derived directly
// from the tilt angle in MachineFrameTransform and no longer lives here.
//
// Design note: this mesh-rotation approach replaced an earlier pre-shear
// method (now removed). While that initial pre-shear method was instrumental
// in getting belt printer slicing off the ground in the first place, its place is
// in the past. A big thank you goes to the Unlayered3D team, who recommended
// switching to a pre-slice rotation stage instead. Doing so keeps the slicing
// operation isometric — no distortion of the sliced geometry — while the
// non-orthogonal machine-axis compensation is confined to a g-code-side shear/scale
// derived from the same tilt angle.
//
// This fixed a number of issues, including several issues noticed by hotcubcar
// regarding adaptive infills not working, gyroid becoming anisotropic, and more
// that were all mostly resolved as a result of the switch.
//
// This also means that the pre-slice rotation transform methodology can be used
// more cleanly on non-belt printers.
