LightBurn 1.7: BSL Support, Trim Shapes tool, Draw Lines update, and more

LightBurn version 1.7.00 has arrived — featuring a new Trim Shapes tool, changes to the Draw Lines tool, a makeover for the Settings window, a major addition to the family of LightBurn-supported lasers, and more.

Download LightBurn 1.7.00 here.

BSL Support

LightBurn now supports Galvo marking lasers with BSL control boards. If your laser uses SeaCAD software by default, it is now compatible with LightBurn.

Native xTool Support

The xTool S1, D1, and D1 Pro are now supported using native xTool commands, instead of their “GRBL compatibility” mode, greatly improving LightBurn’s compatibility with these devices.

Trim Shapes

Use the new Trim Shapes (Scissor) tool to trim lines back to the next place they intersect with another line. This functions very similarly to the Trim option of the Edit Nodes tool, but is now a distinct tool, selectable from the Creation Toolbar.

Read more about the new Trim Shapes tool here.

Draw Lines

We’ve updated the behavior of the Draw Lines tool to make it easier to create curves. You can now press “S” on your keyboard to toggle between placing smooth nodes or corner nodes, and your cursor will change to indicate the type of node you’re currently placing.

If you’re accustomed to the old behavior, that still works too — hold your click and drag while placing a node to create a smooth node and a curve.

Draw Lines will now also Auto-Join two open shapes when you create a new line between them — successful connections are indicated by an animated “marching ants” pattern.

Create Bar Code

We’ve replaced our Create QR Code tool with a new, more powerful option: Create Bar Code. You can now select from over twenty common Bar Code formats, QR Codes included.

Learn more about the new supported Bar Code formats here.

Settings Window Rework

The Settings window had gotten a little cluttered over time, so we divided it into five tabs: Editor Settings, Units and Grids, Display, Import / Export, and Camera.

Find out more about the new layout of the Settings window here.

Shaded Selection Boxes

Selection boxes are now fully shaded in red or green to indicate the type of selection. The behavior remains the same — drag right-to-left to create a green Crossing selection box, which selects anything the box crosses or contains, or drag left-to-right to create a red Enclosing selection box, which selects only objects that are fully contained within it.

Copy Along Path Scaling Option

The Copy Along Path tool now contains an option to apply a scale factor to copied objects, progressively shrinking or enlarging each successive copy.

Other Notable Changes

  • As part of our ongoing process of updating and improving our camera support, we’ve updated the UI of the Camera Alignment process, and added a new AprilTags option to Camera Lens Calibration.
  • Material Test presets added for CO2 and Diode lasers — these presets provide a good starting point for most lasers.
  • Completed field added to the Repeat Marking window, to track the number of completed markings.
