2.17 🚀 Extrusion geometry 🚀

• performance: Tube rendering is now faster and more accurate, thanks to a new custom geometry
• feature: The parser can calculate layer height for each layer. It is used in tube rendering as the line height of extrusions
• options: New option lineHeight, that overrides the height of all extrusion lines in tube rendering

The repo also got some improvements:

• Automatic deploy of the demo when pull-requests are opened and merged

2.16

2.16-alpha fix compatibility with bundlers

• removed the browser field from package.json
• changed the module field to main

2.15 🌈 Multi-color 🌈

• works via detection of T0-T7 commands
• supports systems like:
  • Prusa MMU1/2/3 & XL
  • Bambulabs AMS and AMS Lite
  • 3D Chameleon
  • Enraged Rabbit Carrot Feeder (ERCF)
  • IDEX systems
  • Tool change systems
  • Color mixing nozzles when used with a 'virtual tool' (M164 - Save Mix)

2.14

• api: added dispose method to stop requestAnimationFrame and free memory
• fix: Threejs Lighting was updated to use candela as per r155
• fix: the type for the build volume setting was incorrect, leading to a compilation failure in certain cases

Apart from these changes to the lib, some other changes have been made to the repo, including:

• generated files were removed from the repo
• the examples were grouped together
• the examples received node and security updates
• linting and type checking was added to the github action (running unit tests were already being run)
• a roadmap was created in Github to provide some more focus

I want to thank @sophiedeziel for their help in getting a bit more organized, the sparring on Discord and answering issues over the past few months 🖖

2.13 maintenance release

• new options:
• renderExtrusion
• renderTravel

These options toggle te rendering of extrusion/travel lines

fixed:

• fat lines incorrecty rendering lines between extrusion lines
• [demo] sidebar doesn't update after loading a new gcode file

2.12 Tubular 🤙

• new experimental mode: tube rendering In this mode extrusion lines are rendered using volumetric tubes using THREEjs TubeGeometry. Currently this mode is still under development and considered experimental.

To use it, pass the param renderTubes: true

Known issues:

• performance: rendering takes several seconds or more for large models
• accuracy: line width and line height are not taken into account when setting the tube radius

Thanks to @sophiedeziel for developing this feature.

2.11 🏺 Vase Mode 🏺

• new option: minLayerTreshold If the difference in Z exceeds the threshold a new layer is allocated. If not specified, the default value is 0. (0 meaning a new layer is allocated for each and every increase in Z, however tiny.)

Setting a non-zero value helps to reduce the number of layers that are allocated in memory, which would otherwise cause lagging or even a lock up for spiral vases and such.

Thanks to @raulodev for the initial fix.

2.10 🎃 Halloween release 🎃

This release is all about colors!

• Allow custom colors to be set for:
  • extrusion
  • travel
  • top layer
  • last segment
  • background
• DEMO
  • supports light/dark mode

Colors can be any valid THREE.Color value: css string, color name, hex value, or Color instance.

2.9.4

• Custom non travel moves for CNC'ing

2.9.3

• fixed a bug where the start of the gcode was skipped

2.9.2

• Some Mach3 compatibility changes:
  • allow g00,g01,g02,g03
  • when g2/g3 are given an r too small to bridge the gap, the radius is automatically set to the minimum needed.
• Rudimentary support for G20 (inches). It is basically ignored after any movement is done.

2.9.0

• G2/G3 arcs are supported thanks to @Sindarius
• .d.ts files are bundled into one: gcode-preview.d.ts

2.8.1

• fix ES module

2.8.0

• expose .controls (OrbitControls) to allow setting autorotate etc.

2.7.0

• (experimental) Add drag 'n drop support
• (experimental) Stream support (for both Fetch and drag n drop )
• Naming & cleanup:
  • preview.parser.parseGCode iso now deprecated parseGcode
  • Added .init constructor in favor of now deprecated WebGLPreview
  • The targetId param is deprecated in favor of canvas
  • the deprecated versions remain working for now
• DEMO:
  • Store build volume dimensions in localStorage
  • Make loading of large files faster by increasing the chunk size
• Added examples using Fetch API

2.6.1

• Fix bug where the .lines property was overwritten instead of appended to
• Fix bug where the thumbnails was not properly stored

2.6

• preserve input gcode, including comments, accessible as GCodePreview.parser.lines

2.5

• parse preview/thumbnail generated by slicer

2.4

• improve memory usage by properly disposing of unused geometries and materials.

2.3

• properly handle feedrate

2.2

• add buildVolume param to render the build volume
