LightBurn v0.6.05: Rotary Support, Workspace Camera, color-matched imports, and Inch mode

This is a big one. First, for all the people waiting for rotary support, it's here.

Use Tools -> Rotary Setup to configure and enable it, enter the type of rotary you have and the measurements, and off you go. Ruida users are restricted to using the Y axis (the hardware doesn't support anything else), and for the moment we recommend GCode users stick to the 'A' axis, as the math for Y or Z usage might need tweaking. Please Note: Rotary mode is "sticky" and will stay on when you quit. This is great for people who use it a lot, but might be confusing for those who don't. We'll be making this more visible in the future, but wanted to get this release out for the people held up waiting for it.

Workspace Camera: This one is pretty huge, and we're excited about it. A first pass at the documentation has been written to walk you through setup and calibration. When properly configured, the workspace camera can be used to line up your work with real-world objects on the bed of your machine through a simulated top-down view of the workspace, regardless of the actual position of the camera. Good lighting and resolution is important.

Other additions:

  • Imported object colors are matched to LightBurn palette colors, if possible, or assigned to remaining colors in order if not matched
  • Flood-Fill mode for scanning on slower devices
  • Ability to work in inches
  • Improved Marlin support, with selectable baud rate
  • SVG and AI exporter fixes
  • Fixed save / restore of window position
  • Significantly faster cut planning of complex files (7x speedup in test cases)
  • Numerous other bugs fixed (see ChangeLog for full list)

As always, use "Check for Updates" in the Help menu, or download from our download page.


  • Mike J: “is there a tutorial out on how-to?”

    Check the documentation for how to calibrate and use the camera:

    Other Mike: “When you say rotary is sticky…”

    LightBurn only starts in Rotary mode if that was the mode you left it in, and it’s per-device. Ruida systems store the rotary setting in the controller itself, so we don’t have much choice there, and a lot of users do primarily rotary work, so leaving the mode alone is their preferred way of working. To enable or disable rotary mode, just go to Tools → Rotary Setup and click the “Enable Rotary” check box on or off – that’s it.

  • Cool!

    So there’s been a camera hiding in my E2 all this time!

    Hmmm … is there a tutorial out on how-to?

  • When you say rotary is sticky, does that mean its always in that mode when I restart Lightburn and if yes, how would I get out of rotary mode.

  • Fred – it’s always safe to install over an existing version.
    Alan – A video showing how to set up . . . ? There are a lot of features named here – which would like a video for?

  • Is it safe to install an upgrade over an installed earlier version or is it wiser to remove via control panel the previous version?

    I’ve been using RDWorks to turn on the rotary, but a quick and easy switch to LB for the burn. With a chuck-style rotary, it’s simple. Still, it’s great to see this feature now available in the native LB. One step fewer!
