LightBurn 0.8.07 – Equations, color camera view, grayscale & PPI for AWC, and more
by LightBurn Software December 13, 2018
This one is a pet project of mine: LightBurn’s X & Y position, width, height, scale, and interval entry boxes now support expressions and units. What does this mean for you?
If you type 1/2in, and you’re in mm mode, it’ll turn into 12.7. If you’re in inch mode and type 1/2in, it’ll become 0.5. You can use ft, cm, in, or mm, along with normal math symbols and parenthesis (*/-+). You can combine them, so entering (1/2in + 3mm) * 2.5 + 1ft is valid. You can type 1/300in in the interval box to have it convert “300 lines per inch” into an interval for you. This should make working in mixed units easier.
Over the next release or two I’ll be replacing other number boxes with the new equation entry box, but it’ll take a bit of time.
Cut planner fixes:
The new cut planner had a couple bugs that are now fixed, mostly to do with scans or images being grouped properly, and I’ve added the option to remove overlapping lines as part of cut planning, which preserves inner/outer shape sorting.
A few users posted issues with image scans not lining up with vector art, so that whole pipeline has been improved. There was an issue in the math for images in AI files that caused misalignment for very small images, and a bug found in the precision tracking code for GCode scans when running in inch mode. Both are fixed.
It was possible for prefs to get corrupted in very specific cases if LightBurn crashed when saving or shutting down. A new system has been put into place where your new prefs are saved to a temp file, then swapped with the old ones so you have a backup if anything goes wrong.
The complete list of changes appears below. Download the new version from the Trial Page, and as always, thank you for supporting LightBurn!

– [Oz] Fixed a couple bugs with new cut planner, ordering by group, with scans and images
– [Oz] Fixed an issue where a single object in a layer could be ordered wrong in the new planner
– [Oz] Better prefs handling – auto backup, corruption prevention
– [Oz] Delete overlaps, as part of cut planning
– [Oz] Added “Paste in place” (Alt-V) command
– [Oz] Changed “Hide” to be “Show” so the presense of a check box means the layer is shown

– [Oz] Project Open from the Corel macro now doesn’t change the “last loaded” path
– [SP] Added “Break Apart” function
– [SP] Added “Move H-together” / “V-together” functions (like distribute, but keeps shapes together)
