v0.92-alpha

Snapmaker Orca Full Spectrum v0.92 (Pre-release)

Mixed-filament stability and workflow release.
Based on Snapmaker Orca v2.2.4.

Highlights

Gradient Behavior Is Now Gradual

• Removed the Mixed filament layer cycle setting.
• Reworked non-height-weighted gradient math to use gradual integer cadence by ratio (minority side anchors to 1 layer, majority side scales progressively).
• This prevents abrupt jumps in layer cadence and makes transitions more predictable.

Mixed Filament Indexing And Mapping Fixes

• Fixed mixed-filament row labeling so IDs stay compact after deletions in the Mixed Filaments panel.
• Fixed regeneration order so auto-generated/precomputed mixes are appended at the end of existing mixed rows instead of being inserted at the front.
• Fixed paint/index remapping when adding physical or virtual filaments so existing painted mixed regions keep their intended virtual filament mapping.
• Fixed edge case where the first mixed filament could be temporarily replaced by a newly added physical filament.

Automatic Mixed Filaments Are Editable

• Automatic mixed rows can now be expanded and edited through the gradient controls.
• Edited auto-origin rows are treated as user-managed entries.
• Deleting an edited auto-origin row now keeps that auto pair tombstoned (it will not be regenerated immediately and overwrite user intent).

Gradient Preview Color Fidelity

• Updated gradient preview blending to use the FilamentMixer library path for color reproduction.
• Preview swatches now better match expected mixed output.

Selective Expansion/Contraction Fix

• Updated selective mixed-zone contraction so positive values trim only the outside-facing (visible) boundary band.
• Internal/shared boundaries are no longer symmetrically contracted.
• Outward expansion behavior remains unchanged.

Also Included (v0.91 Carry-Forward Fixes)

• Windows startup/log path handling for non-ASCII usernames (UTF-8-safe path resolution).
• Mixed-filament swatch desync/gray-regression fixes in preview rendering.

Internal/Config Changes

• Removed mixed_filament_cycle_layers from config/UI wiring.
• Extended mixed filament serialized metadata with auto-origin tracking to preserve delete/regenerate intent across reloads.
• Added diagnostic logging around mixed-filament remap and selective-indentation application paths.

Important Notes

• Experimental build with limited testing.
• Some projects may show different gradient cadence behavior due to the removal of explicit layer-cycle control.
• Use at your own risk.

I tried a print using Red Blue and Yellow filaments.
These were the results:

The orange and green look amazing!

The purple needs a little tweaking in the mix ratio, but what an amazing tool.
