Version 0.9

[Iridium-IO]

Highlights

• New Fill Patterns — Spiral, Triangular Hatch, Diamond Crosshatch, and Radial fills.
• Multipass Cutting/Drawing — repeat passes with a configurable Z delta between each
• Toolhead XY Offsets — per-printer offset applied to all generated GCode paths
• Grid Snapping — hold Ctrl to snap drawing, moving, and resizing to the grid
• Overhauled GCode Preview — Pause/Resume/Step controls, a live tool cursor, and customisable preview colours
• Major performance improvements — fill generation is many times faster; reduced memory usage; GCode preview is significantly snappier

Changes

• New Fill Patterns
  • Added four new fill types: Spiral, Triangular Hatch, Diamond Crosshatch, and Radial

• Multipass Support

  • Added Number of Passes and Z Offset Per Pass settings — cut or draw the same paths N times, stepping down in Z between each pass
  • Useful for thicker materials that need multiple light passes rather than a single deep cut

• Toolhead XY Offsets

  • Added Tool Offset X / Tool Offset Y to printer configuration to adjust where your knife/pen is relative to the toolhead.

• Grid Snapping

  • Hold Ctrl while drawing, moving, or resizing any shape to snap to the canvas grid
  • Works for single and multi-element selection during resize. It is however broken if the object is rotated before snapping (I'll fix the math on this eventually)

• GCode Preview Overhaul

  • Added Pause, Resume, Step Forward, and Step Back controls
  • Added a live tool cursor indicator that follows the current preview position
  • Preview lines and cursor colours are now fully customisable
  • Added a Tool Config tab directly on the Preview Page so you can tweak settings and preview them faster

• UI Improvements
  • Redesigned sidebar elements list — groups are no longer nested, and Boolean operation controls have moved directly into the elements list
  • Rearranged File menu — Import SVG and Load Project now appear at the top
  • Tweaked transform gizmo — rounded edge handles, refreshed colours, and better rotate handle positioning
  • Dimension labels are now always visible during any selection, not just while actively resizing or moving
  • Canvas grid is now toggleable from the View menu; the old cutting mat SVG overlay has been removed in favour of the configurable grid
  • Preview Page now uses a solid background canvas for better visual contrast, and makes use of the configurable grid as well.

Tweaks

• SVG Import default stroke thickness changed from 1 to 0.1, to ensure visual positioning is more consistent with the mathematical position (mathematical position is based on a stroke width of 0).
• Improved blade entry-point selection for better cut quality on complex shapes
• Improved the virtual Mica effect and font picker styling

Bug Fixes

• Fixed Start and End GCode not being exported — these were silently omitted from all exports (whoops)
• Fixed SVG Import inflating shape sizes — shapes with thick strokes were being measured including the stroke, causing oversized GCode output
• Fixed Klipper preview speed being hardcoded to 5 mm/s regardless of your configured Drawing Speed
• Fixed ghost elements persisting after Import SVG → Undo → Redo → Delete
• Fixed line shapes being mirrored or flipped incorrectly when resized
• Fixed a crash in the fill processing pipeline
• Fixed various incorrect bounds calculations on the canvas
