LightBurn 1.0 released (insert party noises)

1.0!  It's been a long time coming

This doesn't mean that there is a whole new look, or massive changes, but we've grown our feature list to a point where we think this version has earned the 1.0 label.

There are a bunch of new features, but a lot of the work in this release has gone into things that are more under the hood, adding stability, fixing crashes or common user errors, and improving overall usability. You'll be seeing more of  this in the coming months.

Price change:

We're also going to be raising our prices for the first time in several years, to allow us to expand our support and development teams. The new prices are $60 for the GCode version and $120 for the DSP version, and will go into effect on Monday, August 16th. Renewal pricing is not changing at this time.

What's new in 1.0:

Live / Virtual Arrays

If you create a grid array, you now have the option to make it virtual, meaning that the copies are generated on the fly. The array properties and content can be changed, and the array updates automatically:

With this in place, we'll be working on adding support for these virtual arrays on DSP controllers.

Print & Cut Wizard

Print and Cut is great, but it hasn't been very easy to use. The new Print and Cut wizard walks you through it, making the whole process simpler. We also have a new video up, showing how to salvage a job without markers in it, using the Print and Cut feature. You can find it in Tools > Print and Cut.

Boolean Assistant

Ever have trouble remembering which Boolean option is the right one? You're not alone. The new Boolean Assistant lets you preview the different Boolean options, then pick the one that works. Press Ctrl+B to bring it up.

Two point rotate & scale

Lets you pick a rotation point on a shape, and rotate / scale it freely around that point. Designed to let you align one shape to another, like trying to align text to a slanted edge. Press Ctrl+2 to start the tool, and follow the prompts at the bottom of the screen.

Click filled areas to select or drag

If you normally use LightBurn in 'Filled rendering' mode, life just got a little bit easier. You can now click anywhere inside a filled shape to select it.

Other notable changes

  • Adjust Image tool is much more robust
  • Ramp mode for vectors is now 2x faster
  • Automatic view panning while dragging shapes
  • Export to SVG will now retain image masks
  • Measure tool now includes selected shape width / height, and does a better job of identifying arcs
  • Rewrote serial library used for Ruida communication - now significantly faster, and more robust
  • Support for multiple Ruida controllers when using Packet/USB mode
  • Print (to printer) now scales correctly
  • Can now import / export all preferences, making it easier to share settings between computers
  • Edit > Machine Settings now supports Marlin

As always, you can download the latest version from our Download / Trial page, or by using the 'Check for Updates' feature in the Help menu in LightBurn.  Thank you for supporting LightBurn.
