- Add BeltBackTransform class that inverts the shear/scale matrix and
applies it in GCodeWriter::to_machine_coords() so G-code outputs in
the machine's physical coordinate space, gated by new
belt_gcode_back_transform config option
- Extend belt floor clipping to all three tree support pipelines
(Prusa-style, Orca organic, TreeModelVolumes) with per-layer polygon
clipping, anti-overhang integration, and belt raft extension layers

offset, collision calculation index bug, and first-layer brim/empty
layer checks for belt printers

add 1/sin(a) transform, idea taken from blackbelt cura plugin
Things work now (turns out I've been using the wrong set of transforms)
- Replace monolithic belt rotation transform with independent per-axis
shear controls (mode/angle/source-axis for X, Y, Z) and G-code axis
remapping, giving full flexibility to match any belt printer's
coordinate system
- Remove all rotation mode logic and intermediate type+axes dropdowns,
simplifying the pipeline to pure shear matrices while preserving the
default behavior (Y += Z*cot(45deg) with identity remap)
- Clean up GCodeWriter, GCodeProcessor, and GCodeViewer for the new
shear-only model; expose 12 new settings in printer UI via
Tab.cpp/Preset.cpp
Implement belt printer tilted slicing
Implement the core belt slicing pipeline that makes the slicer
tilt-aware:
Step 1: GCodeWriter::to_machine_coords() - R(+alpha, X) rotation
from slicing frame to machine frame
Step 2: PrintObject - belt-rotated object height calculation
(y*sin(a) + z*cos(a)) for correct layer count
Step 3: PrintObjectSlice - apply R(-alpha, X) rotation trafo so
horizontal slice planes correspond to belt-parallel planes,
with Z-shift computed from model volumes
Step 4: GCodeProcessor - machine-frame preview (no transform needed)
Step 5: 3DBed - rotate bed visualization about X by belt angle
Fix: belt surface IS the build plate, no mesh rotation
Currently still slicing perpendicular to the belt normal. Need to figure out why.
Fix G-code Z sign: use R(-alpha, X) so Z+ is away from belt
The previous R(+alpha, X) transform produced negative Z values
(-y*sin(a) term dominated). Changed to R(-alpha, X) which gives
machine_z = y*sin(a) + z*cos(a), always positive for points
above the belt surface. Z increases with each layer as expected.
reverting and changing slice methodology
Add pink slicing direction arrow from origin
Shows the effective slicing direction (gantry normal) as a pink
arrow from the origin. Shorter and wider than the gravity arrow.
Direction: R(+alpha, X) * Z = (0, -sin(a), cos(a)), which is
the layer stacking direction in the original mesh frame.
Fix slicing arrow visibility and add raw G-code toggle
- Disable depth test for pink slicing arrow so it renders on top of
the tilted bed geometry (was being occluded)
- Remove unnecessary 5mm Z-offset from arrow position
- Add m_belt_show_raw toggle to GCodeViewer
- Add "Show raw G-code (slicing frame)" checkbox in legend when
belt mode is active
Implement to_machine_coords inverse rotation for belt printer G-code
The slicing pipeline rotates the mesh by R(-alpha, X) and shifts Z to
start at 0. The G-code output now undoes this transform via
to_machine_coords: R(+alpha, X) * T(0,0,+z_shift), recovering the
original machine-frame coordinates where Y is horizontal and Z is
vertical.
Changes:
- GCodeWriter: implement to_machine_coords with inverse rotation + Z-shift
- GCodeWriter: add belt_z_shift member and setter/getter
- GCode.cpp: compute Z-shift from print objects (same logic as
PrintObjectSlice) and pass to writer; write z_shift to G-code header
- GCodeProcessor: parse belt_z_shift from G-code header
- GCodeViewer: store belt_z_shift from processor result
Wire raw G-code toggle to apply slicing-frame view transform
When "Show raw G-code (slicing frame)" is checked in the preview
legend, the view matrix is modified to apply R(-alpha, X) * T(0,0,-z_shift)
to the toolpath rendering. This shows the G-code as it was during
slicing: rotated part with horizontal layers.
Default (unchecked): machine-frame view — upright part with tilted layers.
Remove belt printer placeholder comment from GCodeProcessor
The preview now correctly displays machine-frame G-code with the
optional raw view toggle. No transform is needed in the processor.
- Implement core belt slicing pipeline: R(-alpha, X) mesh rotation in PrintObjectSlice with corrected object height calculation for proper layer count
Add to_machine_coords() in GCodeWriter to convert slicing-frame coordinates back to machine-frame, propagated through GCode,
GCodeProcessor, and GCodeViewer
Add belt-mode UI: tilted bed visualization, slicing-direction arrow, and raw G-code toggle to switch between machine-frame and slicing-frame views
This is a combination of 6 commits.
checkpoint 1: initial MVP. Slicing functions, but rotates instead of skews are happening and a lot of other stuff too
getting somewhere, getting to the point where I need to figure out how to verify this stuff
this appears to be a dead end.

I'm pretty sure we've completely lost the plot at this point and need to restart this process...

Fix crash in PA calibration pattern generation
Reset current extruder ID and clear pointers in set_extruders to prevent dangling pointers when extruders are recreated. Also fixed undefined behavior by checking if the vector is empty before taking max_element.

* Emit Disable Power Loss Recovery
Now only works if it's enabled but the goal it's to force disable it.
With this change it will always emit the command for BBL or Marlin 2.

* Refactor power loss recovery G-code comments
* Return empty power loss recovery when no compatible printer
* Update power loss recovery comments
Update label and tooltip for power loss recovery
* Add enum for power loss recovery mode
Refactored power loss recovery configuration to use a new PowerLossRecoveryMode enum instead of a boolean. Updated GCodeWriter and related logic to handle the new enum, allowing for 'printer_configuration', 'enable', and 'disable' options. Updated config handling, legacy value conversion, and default values accordingly.
* Update PrintConfig.cpp

Spiral Z-Hop resolution
Use slicing resolution to determine segment count for emulated spiral Z-hop
What’s changed
The number of linear segments used to approximate a spiral Z-hop is now derived from the PrintConfig resolution value.
The segment count is clamped to a safe range (4–24) to avoid excessive G-code generation or MCU queue overflow.
Why
Previously a fixed 24 segments were always used, regardless of model resolution.
For small-radius spiral lifts this was excessive and could overwhelm some printers.
Adapting segment count to resolution ensures smooth motion where needed, but lighter G-code where possible.
Details
m_resolution is now stored via apply_print_config().
_spiral_travel_to_z() uses this value to compute segment count dynamically.
Only the linear-segment fallback path is affected; G2/G3 arc-fitting remains unchanged.
* Add ability to disable Power Loss Recovery

* Attempt to resolve Unknown option exception: disable_power_less_recovery

- Support Marlin 2
* Update comments and power loss recovery handling
* Implement power loss recovery G-code commands
Added functions to start and end power loss recovery with appropriate G-code commands and comments.
* Add power loss recovery methods to GCodeWriter
* refactor and fix build errors
