Version 0.9

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

Full Changelog: v0.8...v0.9

Version 0.8

Changes

• Klipper Export: Preview Bounding Box Pass

  • Added the ability to send a preview rectangle that encompasses all cutting/drawing moves to Klipper. This preview runs in the travel layer above the surface, so you can check if your materials are properly aligned before anything is actually cut/drawn. #12
  • Added Preview Start GCode and Preview End GCode to the Printer configuration menu that are run when the preview export is used
     
  

• Colour selection improvements

  • Added an eyedropper to the colour picker UI
  • The Extract Single Colour configuration option now uses the colour picker instead of being a textbox
     
  

• Grid Improvements

  • Added full configuration support for the canvas grid, including spacing, offsets and colour options
     
  

• Added copy/cut/paste support

  • Shapes can be copied and pasted using Ctrl+C/Ctrl+X/Ctrl+V as you'd expect
  • Added an Edit menu with these buttons.

Tweaks

• SVGGroup support on imports - no longer flattens all SVG layers/groups anymore
• UI Polishing and layout tweaks
• Improved object selection gizmo performance and rendering.

Bug Fixes

• Fixed a regression that broke zero-width SVG paths (i.e. perfectly vertical or horizontal lines) from being imported

Full Changelog: v0.7.1...v0.8

Version 0.7.1

Changes

• Export Canvas as SVG
  • You can now optionally export everything as an SVG
    • This will be important as a future update will introduce group support which will break existing saves files, so this version will be necessary to export projects to SVG first so they can be imported in newer versions.
• Performance Improvements
  • Refactor SVG Importer to avoid breaking down imported paths into tiny lines. This means major performance improvements particularly for larger files, which should no longer be as laggy on the canvas.
  • This also improves the quality of imported paths as they are no longer approximated (except arcs. I can't do arc math)
• SVG Feature support
  • Added support for: SvgPolygon SvgPolyline
    • Improved SvgLine support to now allow clipped lines to "work"
  • Added matrix transform support for imported shapes

Fixes

• Fix improper scaling if an imported SVG had a Viewbox set or had undefined units
• Fix SVGLine import process for accurate rendering
• Fix ordering of imported SVG shapes
• Fix inadvertently adding strokes to shapes that shouldn't have one on import
• Tweaked - open paths that have a fill applied will now implicitly close themselves when generating GCode so that visual fills are more intuitive.

Full Changelog: v0.7...v0.7.1

Version 0.7

Highlights

• Project save/load - Save and reload full projects
• Shape Handling - Major rework, now supports: multi-select and transform, undo/redo, editing of stroke/fill. Shapes can also be merged using boolean union/subtract/exclude/intersect modes.
• Redesigned GCode Preview - Improved layout, performance and added syntax highlighting
• Printer (Machine) Management - Add/remove machines with independent config.
• Custom Start/End GCode - added support for custom GCode that can be stored per-printer profile
• Added Shape fill features - control shading detail of shapes when using Draw mode

Changes

• Project Save/Load
  • Save and load projects to/from disk
  • Currently doesn't save independent config settings (planned)
• GCode Generator
  • Major performance and functional improvements
  • Cutting Mode:
    • Added an initial swivel to ensure the knife faces the correct direction before the first cut.
    • Now optimises path selection to account for the swivel direction of the blade between each shape. For example, if one shape finishes being cut in an easterly direction, the optimiser will choose to start the next shape on an easterly path too in order to avoid accuracy issues with the blade swiveling to the new direction. This improves the accuracy and quality of cuts especially on fine details.
    • Other optimisations to reduce tearing at corners of shapes
  • All modes: Improved travel and path functions for faster completion as well as fixing several artifacts.
• Canvas Editing
  • Shapes can now have their fill/stroke edited in the canvas, including editing of imported SVG shapes
    • Note that the thickness of the stroke does not affect the output GCode, it is purely for visual separation. However, setting it to zero will disable the stroke in the output as you would expect
• Shape Combining
  • Shapes can be combined using union, intersect,subtract or exclude modes.
• Undo/Redo Support
  • Added support for undo/redo operations. This is still in process so not everything is implemented yet, however most shape-related transformations are supported.
• New GCode Preview
  • Improved GCode preview and rendering
  • Added syntax highlighting to make it look pretty
  • Much better performance when scrolling through large Gcode
• Printer Configs
  • Printer configs now open in a separate window, and different printers can be added/removed
  • Canvas alignment / cutting mat selection has also been moved to the printer configuration section
• Transform Gizmo Rework
  • Made the transform overlay for shape manipulation much more robust; it now supports multi-object selection and manipulation, as well as better scaling/zoom support
• New Processing Options
  • Shading density controls to let you control hatch/fill outputs based on the brightness of colours
    • Hovering over the Threshold configuration option will show/hide shapes on the canvas depending on which ones meet the threshold.
  • Option to choose between fill first or stroke first when drawing.
• SVG Import
  • All imported SVGs are now converted to native shapes for simplified processing
  • Basic (I mean basic) support for clipped and masked imported shapes
  • Note: Gradients and other fancy SVG features are not supported (for best results, always convert everything to paths first anyway)
• Platform
  • Update to .NET 10
  • Update WPFUI to 4.2.0

Tweaks

• Mirroring shapes now correct for shape rotation, and is intuitive
• Keyboard Shortcuts: (TODO)
• Made preview lines transparent in the preview pane to see crossing lines more easily
• Element types are now listed next to their name in the sidebar
• Added a toggleable Grid overlay to the canvas.

Fixes

• Hidden objects on the canvas are no longer added to generated GCode
• Fixed cutting mode generator to reduce corner-tearing artifacts
• Fixed Overcut setting jumping to the start of a line if it isn't part of a closed shape
• Drawing mode now respects whether a shape has a fill colour or not before it renders fill Gcode
• Fixed several crashes when trying to import funky SVGs.

Version 0.6

Changes

• Improved Fill Processor
  • massive performance increase using PolyCut.Core when generating complex filled paths (over 10x faster)
  • fixed overall logic of the processor to fix several bugs and unwanted effects.
• New configuration options
  • Filltype is now a dropdown list (to make way for new filltypes soon)
  • You can now choose whether pens can draw over shape boundaries to speed up hatching designs (rather than lifting the pen after each stroke) - previously this was assumed.
• New GCode Preview Page
  • Optimised rendering of GCode paths - lines now smoothly trace out from start to end rather than rendering the whole line at once. It looks glorious
  • Added new preview speed controls
  • Spent an obnoxious amount of effort to emulate the Mica effect on the Preview toolbar (please notice this :) )

Fixes

• Fixed issues with hatch/crosshatch filling:
  • Some shapes would not be filled if they were too far from other shapes
  • Some lines would "shortcut" across gaps they shouldn't when filling
• Fixed GCodePlot not honouring the Optimisation setting. See here: arpruss/gcodeplot#43
• Fixed Cutting Mat and Working Area visibility switches not working
• Fixed crash when adding a textbox after switching back from the preview page.
• Tabbing between number boxes in the Element Properties tab now selects the number for quicker editing.

Known Issues

• See document here

• Note Stroke widths on all objects are not included in geometry calculations. If you have massively thick strokes on your shapes, the processor will ignore it when calculating shape outlines and locations, and the resulting size of the shape will be incorrect. You should consider a stroke as a guideline for the tool path, rather than a component of the shape itself.

Version 0.5.1

Changes

• Predominantly bugfix release
• UI Tweaks
  • Updated canvas colour and removed laggy drop shadow
  • Sidebars can now be resized
  • Added hover highlight to Elements list for visual feedback
  • Fixed default scaling/positioning of main canvas
• Backend
  • started splitting massive SVGPage.xaml file into smaller UserControls

Fixes

• Fixed duplication of generated toolpaths when parsing SVG files (every shape would get processed twice, resulting in double cuts/draws - whoops)
• Reduced thickness of drawn shapes to help with size accuracy when processing
• No longer generates a PolyCut.exe.WebView2 folder in your working directory (which can be annoying) - this is now generated in the Temp folder instead

Known Issues

• See document here

Version 0.3

New Features

• Added basic shapes (line, rectangle, ellipse, text) that can be drawn directly onto the canvas
  • Note the tools are still buggy, for example:
    • If you drag to create a shape off the page, it will glitch and may leave a ghost element behind
    • Text cannot be edited after it is created; you also have to set the font and size in advance.
• Visual changes:
  • The cutting mat overlay can now be hidden on the main canvas
  • The canvas colour can be changed between light and dark appearances.

Fixes

• Elements are now correctly unselected when you click off them
