What's New in LightBurn 1.5

Radius Tool Updates

Radius Tool Supports Bézier curves

The Radius Tool now supports adding a radius to corners connecting to Bézier segments

Using the Radius Tool with curved segments

Radius Drag Handles Added

Starting in LightBurn 1.5, rectangles have an additional handle available that acts as a shortcut for the Radius Tool. Drag the blue handle away from the corner to increase the radius of all four corners, and drag toward the corner to decrease the radius. Dragging vertically creates a reversed radius, with a bite taken out of the corner.

Improvements For Galvo Lasers

Global Passes Setting

Starting in version 1.5, the Cut Settings Editor for galvo lasers has a new Global Passes setting. Increasing this value will repeat all sub-layers in a layer the number of times specified.

Framing Enabled for Galvo Device Rotary Engraving

LightBurn now supports framing on galvo lasers when doing rotary engravings.

New Alignment Features

Alignment Guides

While dragging to draw, move, or scale objects, holding Alt will produce alignment guides for edges and midpoints of existing objects.

Draggable Guidelines Added

Horizontal and vertical guidelines can now be created by dragging from the ruler area of the LightBurn workspace. Guidelines can be treated like any other line, including locking them to prevent accidental movement.

Tool Enhancements & New Taper Warp Tool

Slot & Tab Resizer Improvements

Starting in version 1.5, the Slot & Tab Resizer has an Apply button to apply changes without closing the window. This makes performing multiple operations, such as changing both slot depth and slot width, more convenient.

Trace Image Transparency

Image Trace can now trace an image's transparency channel.

Enabling Trace Transparency provides an easy way to trace the edges of an image with a transparent background

Measure Tool Axis Snap

While using the Measure Tool, hold Shift and drag to snap to horizontal, vertical, and 45 degree angles.

Dragging with axis snapping

Outer Border Added To Material Test

The Material Test Generator now automatically generates a border to cut out the test grid. Use the Edit Border Setting button to change cut settings.

Taper Warp Tool Added

LightBurn now has a Taper Warp Tool for improved rotary engravings on tapered objects.

Select which side of the artwork is at the top of the object, measure the object, and LightBurn will automatically calculate and apply the warp needed to counteract the distortion produced by engraving on a tapered object.

Drag Handle For Polygon Side Count

When using the Polygon Tool, there is now a purple handle that can be dragged to change the number of sides. This has the same result as changing the Sides property in the Shape Properties Window.

Using the new Polygon Drag Handle

New Device Types Added

New Dummy Machine Type

When creating a laser manually, LightBurn now has a No Machine option, simplifying the process of running LightBurn without a specific device connected.

Custom GCode Added

The new Custom GCode device type can be used to customize LightBurn's GCode output to control less common or custom devices.

New Shape Property Added For Text

Starting in version 1.5, text objects have a new Shape Property called Squeeze that works with the Max Width property. With Squeeze enabled, scaling with Max Width will scale the text horizontally to maintain a consistent height. With Squeeze disabled, text scales proportionally to maintain a consistent appearance.

Using Max Width with Squeeze on and off

Other UI Improvements

Copy Along Path Improvements

Starting in version 1.5, Copy Along Path will use the nearest point on the path as the start point.

Copy Along Path now automatically starts from the nearest point on the path

Merge Button Added to Material Library

The Material Library window now has a Merge button. Use this button to merge a material library on disk with your active material library.

Zero Out Rotary Axis

When working with a rotary, LightBurn now has the ability to reset the rotations on the rotary axis to 0.

Warning For Users of 32-bit Windows Computers

LightBurn 1.5 will be the last version of LightBurn to support 32-bit versions of Windows.
