LightBurn 0.9.17 - Tool layers, single line fonts, image masking, and much more

This is a fairly large release, so we'll go over the big things first:

Tool Layers

These are layer colors that will never be sent to your laser, and are designed to be used as rulers, guides, alignment tools, paths for text, image masking, and so on.  They will never be sent to the laser, have no cut settings, and you can decide whether or not they are using when calculating job origin.  For example, if you often draw a frame around your design so you can center it properly, but set that layer not to output, you'd now make a tool layer set with 'Frame' enabled.

Tool layer example

The new tool layers are T1 and T2, at the end of the color palette.

Single Line Fonts

SHX fonts are quite old, and came from AutoCAD where they were originally made for plotters.  Some SHX fonts are truly "single line" while others are more complex, but the single-line versions are perfect for when you want text, but you want it drawn quickly.

Single-line font example

In the settings, under File Settings, there's a new button to choose the location of your SHX fonts folder.  Download some SHX fonts and tell LightBurn where to find them and they'll show up in the fonts drop down.  We have a video tutorial for this here: https://youtu.be/-Uj6Dz8g0ko

Image Masking (live crop)

We've added the ability to mask an image using another shape, but it's 'live'.  You can manipulate the mask shape and the image updates on the fly.

Live image mask example

Select an image and a shape (or group), right click and choose 'Apply mask to Image'.  We have a video tutorial for this feature here: https://youtu.be/1q4WyVMfhXg

Re-start a job part way through

If you open the Preview window in LightBurn, you'll notice a new button:

If you have a file that was stopped before it finished, you can drag the time slider in the preview window to the point where it stopped, then click the 'Start here' button to tell LightBurn to begin running the job from wherever you are in the preview.  This works on all controllers - GCode or DSPs.

Other notable changes

  • The font list in LightBurn now has 'favorite' and 'recent' fonts
  • Stuttering at the start of image engraving for GCode devices has been greatly reduced or eliminated
  • Illustrator users can now set SVGs to import at 72 DPI instead of the InkScape standard of 96 DPI

There's a lot more in here, so the full list of changes is shown below.  As usual, use the 'Check for Updates' feature in LightBurn to download, or you can download from our Trial / Download page.  Make sure your license is not expired if you download manually.
