Master Curved Text In LightBurn: A Complete Guide To Wrapping And Bending Text For Laser Engraving
Curving text in LightBurn is achieved either by manipulating the dynamic blue bend handle on a text object for quick arcs, or by utilizing the Apply Path to Text feature to wrap characters around custom vector shapes. This step-by-step guide covers the technical workflows, spacing calculations, and kerning adjustments required to achieve distortion-free typography on circular and irregular laser engraving blanks. Following these exact design workflows ensures clean, professional alignments without damaging your raw materials or wasting valuable production time.
Pre-Design Checklist & Software Environment Setup
Before attempting to curve text in LightBurn, you must configure your workspace and gather precise measurements of your physical engraving blanks. Attempting to bend text without a scaled vector reference often leads to misaligned burns and wasted inventory. Use the following preparation checklist to establish a highly accurate design environment.
Essential Equipment, Tools, and Materials
- Digital Calipers: Required for measuring the exact outer diameter of circular blanks, such as wooden rounds, slate coasters, or tumblers.
- LightBurn Software: Version 1.0 or higher is recommended to ensure full stability of the path-alignment engine and dynamic text properties.
- Vector Guide Shapes: A digital circle, ellipse, or custom drawn spline inside LightBurn that matches the physical dimensions of your workpiece.
Technical Prerequisites & Design Standards
- Vector Path Understanding: Text can only be applied to open or closed vector paths. It cannot be applied to raster images or un-traced bitmap graphics.
- Active Text Status: Text must remain as editable text to utilize dynamic bending properties. Once converted to raw vector paths, typographical properties like kerning and font families can no longer be modified.
- Tool Layers Usage: Always utilize LightBurn's non-printing Tool Layers (T1 or T2) for your reference paths. This prevents the laser from cutting or engraving your guide geometry.
Budget & Time Benchmarks
- Estimated Software Setup Time: 5 to 10 minutes.
- Project Cost: Free (built-in features within the standard LightBurn software license).
Step-by-Step Workflows for Bending Text in LightBurn
LightBurn offers two distinct methods for curving text. The first is the quick-bend blue handle method, ideal for simple, non-guided visual arches. The second is the path-association method, which wraps text precisely along any drawn vector line, circle, or custom curve.
Step 1: Create and Format Your Text Object
Before applying any curve, you must initialize your text with the correct typographical parameters.
To start, click the Write Text tool (represented by the large capital letter A on the left toolbar) or press the keyboard shortcut Ctrl + T. Click anywhere in your workspace and type your desired phrase.
Once typed, press the Esc key to return to the Selection Tool. With the text selected, navigate to the top font menu to select your typeface. Clean sans-serif fonts such as Arial or Montserrat deform more predictably when curved, while script fonts with overlapping cursive glyphs may require manual adjustment later. Set your initial text height and alignment to center-aligned to ensure even distribution along the curve.
Step 2: The Quick-Bend Method (Using the Blue Handle)
For simple arched layouts where you do not need to match a strict geometric diameter, use the built-in bending tool.
Select your text object using the standard selection cursor. When selected, a bounding box will appear around your text, consisting of several small squares at the corners and midpoints.
Look directly below the center-bottom edge of your text bounding box. You will see a single, distinct blue dot. Hover your mouse cursor over this blue dot until your cursor changes into a curved double-headed arrow.
Click and hold the blue dot, then drag your mouse slowly upward to curve the text into a convex arch, or drag it downward to create a concave dip.
Pro-Tip: If you hold the Shift key while dragging the blue bend handle, LightBurn will restrict the bending action to fixed, symmetrical increments, making it significantly easier to maintain a balanced, horizontal orientation.
Step 3: Draw a Precise Vector Guide Path
For precise wrapping around circular objects like coasters, cutting boards, or circular emblems, you must establish a physical reference path.
Select the Ellipse Tool from the left toolbar (or press Ctrl + Shift + E). To draw a perfect circle rather than an oval, hold down the Shift key while clicking and dragging in the workspace.
With the circle selected, locate the width and height input boxes in the top toolbar (labeled W and H). Enter the exact dimensions of your target boundary. For instance, if you are engraving a 100-millimeter slate coaster and want a 5-millimeter margin, set your circle's dimensions to exactly 90 millimeters.
In the color cut palette at the bottom of the screen, select T1 or T2 (the orange and blue tool layers). This converts your vector circle into a non-printing layout guide, meaning it will remain visible on your screen for design purposes but will never be sent as an active cut instruction to your laser.
Step 4: Align and Attach Text to the Vector Path
To wrap the text around your newly constructed circle, you must select both elements and execute the path-binding command.
Using the selection cursor, click on your text object. Next, hold down the Shift key and click on your vector guide circle. Both items should now show crawling selection lines (marching ants), indicating they are active.
Right-click anywhere inside the empty workspace to open the context menu. From this menu, click Apply Path to Text.
The text will instantly snap to the perimeter of the circle. By default, LightBurn aligns the baseline of your text characters directly to the vector line of the path.
Step 5: Adjust Vertical Offset, Spacing, and Rotational Position
Once the text is bound to the path, it may not sit in the exact position or orientation you require. Use the dynamic text property inputs to finalize the placement.
Select only the text object. Look at the top toolbar in LightBurn, specifically the text options bar that activates when text is highlighted.
To move the text around the circumference of the circle, look for the blue dot that has now relocated to the attachment point on the circle. Click and drag this dot to rotate the text along the path.
To adjust the vertical clearance of the text relative to the line, adjust the V-Spacing parameter in the text settings bar. Increasing this value pushes the text outward, away from the center of the circle, while decreasing it pulls the characters inside the path.
Adjust the H-Spacing (horizontal tracking/kerning) to expand or compress the distance between individual letters. This is critical for tight circular paths where letters can easily bunch up and overlap.
Warning: Be careful when using high V-Spacing values. Pushing the text too far from its original guide vector can cause severe character distortion, stretching the tops of the letters unnaturally. If you need a larger radius, it is always better to resize the guide circle itself rather than over-extending the vertical spacing.
Step 6: Bake the Layout (Convert to Vector Path)
Once you are satisfied with the curve, spacing, and location of your text, you must stabilize the design so it cannot be accidentally shifted or corrupted during file transfers or scaling operations.
Select the curved text object. Go to the top menu bar, click on Edit, and select Convert to Path (or use the shortcut Ctrl + Shift + C).
This action destroys the dynamic link between the text and the vector guide. The text is now a set of permanent, static vector curves. You can now safely select the guide circle and delete it, or move the curved text independently without losing its shape. Note that after this conversion, you will no longer be able to edit the spelling or change the font of the text.

Technical Text Manipulation Settings & Tolerances
The following table provides a comprehensive reference of the key settings inside LightBurn that control how text interacts with circular and curved paths. Use these ranges and units to plan your file setup.
| Setting Name | Software Interface Location | Recommended Range / Unit | Functional Impact on Engraving |
|---|---|---|---|
| V-Spacing (Vertical Offset) | Top Text Options Bar | -50.0 to +50.0 mm | Controls the distance between the text baseline and the path. Negative values pull text inside a circle; positive values push it outside. |
| H-Spacing (Horizontal Kerning) | Top Text Options Bar | -10.0% to +100.0% | Adjusts the space between individual characters. Crucial for keeping letters readable on small-diameter, tight radiuses. |
| Align to Path | Text Settings Dropdown | Top, Bottom, Middle, Baseline | Determines which part of the font's bounding box references the vector path line. Use "Middle" for balanced centering. |
| Text Alignment | Main Toolbar (Left/Center/Right) | Center (Highly Recommended) | Determines the starting anchor point on the path. Center alignment ensures symmetrical wrapping on circles. |
| Tool Layers (T1 / T2) | Bottom Color Palette | Non-Output Cut Settings | Used to hold the guide shapes. Prevents the laser from engraving or cutting out your circular alignment guides. |
Common Curve Failures & Software Fixes
When curving text in LightBurn, users frequently encounter rendering errors, flipping text, or structural issues. Use these field-tested diagnostic steps to quickly resolve software conflicts.
The Text Appears Upside Down or Inside the Circular Path
- Root Cause: The starting vector direction of your guide circle is running counter-clockwise, or the text horizontal/vertical alignment settings are set to read from the internal boundary.
- Actionable Fix: Select only your guide circle, right-click, and choose Make Path (if it is a basic shape), then select Edit > Reverse Path Direction. Alternatively, select your text, locate the V-Spacing tool in the top menu, and input a negative value to force the characters to flip to the opposite side of the vector line.
Deleting the Guide Circle Instantly Flattens the Text
- Root Cause: The text and the vector circle share an active, dynamic dependency. Deleting the parent vector breaks the math engine, forcing the child text to revert back to its default straight line configuration.
- Actionable Fix: Select your curved text before deleting the guide circle. Navigate to the top menu and select Edit > Convert to Path (or press Ctrl + Shift + C). Once converted to raw vectors, the circle can be safely deleted or moved without affecting the shape of the text.
Letters Bunch Up and Overlap Near the Center of the Curve
- Root Cause: The radius of your guide path is too small relative to the height and horizontal footprint of your text. When text wraps along a tight inner arc, the tops or bottoms of the characters naturally collide.
- Actionable Fix: First, try increasing the H-Spacing parameter in the text options bar to manually push the letters further apart. If this looks unprofessional, you must either decrease the font size, switch to a narrower sans-serif font family, or increase the overall radius of your guide circle to distribute the letters across a wider perimeter.
The Blue Bend Handle is Missing from the Selected Text
- Root Cause: The text object has already been converted to a path, grouped with another object, or is part of a complex multi-line selection that disables raw text properties.
- Actionable Fix: Ensure the text is fully ungrouped by pressing Ctrl + U. If the bounding box handles are red or green points instead of simple corner squares, the text has been flattened into standard vector shapes and can no longer be dynamically bent. You must re-type the text using the Write Text tool to generate a new active text block.
Frequently Asked Questions
How do you curve text around a circle in LightBurn?
To curve text around a circle, create your text using the text tool and draw a circle using the ellipse tool. Select both the text and the circle simultaneously, right-click, and select Apply Path to Text. The text will automatically wrap along the perimeter of the circle.
Why does my curved text disappear or flatten when I delete my guide circle?
This occurs because the curved text is still dynamically linked to the circular vector path. To delete the circle without losing your curved layout, select the text first, navigate to Edit > Convert to Path, and then delete the guide circle.
Can you curve text downwards or upwards using the blue dot?
Yes, selecting a text box reveals a single blue handle at the bottom center. Clicking and dragging this handle upward bends the text into an arch (curving upwards), while dragging it downward bends it into a bowl shape (curving downwards).
How do I adjust the spacing between letters after curving text?
Select the curved text object and locate the H-Spacing (Horizontal Spacing) field in the text settings toolbar at the top of the screen. Increase the percentage value to spread the letters further apart, preventing overlaps on tight curves, or decrease it to bring them closer together.
How do I center curved text on a tumbler or round coaster?
Draw a guide circle on a Tool Layer (T1/T2) matching your blank's dimensions, then use Apply Path to Text. Rotate the text using the blue alignment handle until it is centered, and use the V-Spacing control to offset the text perfectly between the outer edge and the center point of the design.
Elevate Your Laser Engraving Designs with Precise Vectors
Now that you understand how to curve and align text in LightBurn, you can confidently customize circular blanks, curved borders, and specialized merchandise without alignment errors. To guarantee the highest precision, run a low-power framing pass on your laser before executing your final engraving to ensure the curved paths perfectly trace your workpiece.
