v0.9 Pre-release

EXPERIMENTAL BUILD - LIMITED TESTING Based on Snapmaker Orca v2.2.4

v0.9 full spectrum pre-release focuses on mixed-filament workflow UX and stability.

What's New in v0.9

Mixed Filaments UI/UX Overhaul (v0.9)

  • Replaced the blocking mixed-filament popup with an inline expand/retract editor.
  • Added row hover feedback and click-anywhere row activation for custom mixed filaments.
  • Added dynamic mixed-filament panel resizing with an expansion cap sized for up to two expanded rows.
  • Simplified editor flow to Simple mode only (mode selector removed from the inline editor).
  • Moved gradient selector inline with filament selectors for faster editing.
  • Reworked filament selectors into compact color swatch pickers with F1/F2/... labels.
  • Simplified pattern editing:
    • removed insert dropdown/button flow,
    • kept direct filament buttons for appending pattern tokens.
  • Moved preview labels into the preview bar itself (Preview + ratio overlay), with outlined text for readability.

Mixed Filaments Behavior and Reliability (v0.9)

  • Automatic mixed filaments are now read-only in the inline settings editor.
  • Automatic mixed filaments can now be deleted from the UI.
  • Added persistent deleted-state storage for mixed filament rows so deleted auto rows stay deleted after refresh/restart.
  • Excluded deleted rows from enabled/displayed virtual filament mapping.
  • Improved change propagation so mixed-filament edits correctly mark config/project dirty states.
  • Addressed mixed-filament editor collapse/refresh stability issues.

Local Z Dithering and Prime Tower Handling (v0.9)

  • Enhanced Local-Z phase-b tool change handling when wipe/prime tower is enabled.
  • Added an unplanned Local-Z tool-change path in wipe tower integration to emit proper tool-change/wipe G-code outside the preplanned per-layer sequence.
  • Enabled Local-Z phase-b execution with wipe tower active (still blocked when wiping overrides are active).
  • Restored pre-pass extruder state after Local-Z phase-b so subsequent wipe/prime tower planning remains synchronized.
  • Improved Local-Z + wipe tower diagnostics/fallback logging for troubleshooting.

Dark Mode and Visual Consistency (v0.9)

  • Added dark-mode-aware styling to mixed-filament rows and inline editor controls.
  • Fixed dark-mode text contrast for mixed-filament row labels and controls.
  • Updated gradient/preview border handling for better dark-mode contrast.
