-
Coordinate Entry
The Move tool allows direct input of X and Y coordinates, providing precise control over design placement. Entering the coordinates representing the machine’s center, often found in the device settings, positions the design at this central location. This direct coordinate entry eliminates the need for manual adjustments or estimations, streamlining the centering process. For example, entering X=150mm and Y=100mm moves the selected object’s origin to those precise coordinates relative to the currently selected User Origin.
-
Nudging
Fine-tuning design position is achieved through the nudge functionality within the Move tool. Small incremental movements, controlled by arrow keys or on-screen buttons, allow for precise adjustments relative to the machine’s center. This is particularly useful for final alignment adjustments after initially positioning the design using coordinate entry. Nudging ensures perfect centering even when dealing with intricate designs or tight tolerances.
-
Selection Sensitivity
The Move tool offers selection options affecting how designs respond to movement commands. Selecting individual elements, groups, or the entire design impacts the overall positioning relative to the machine’s center. Understanding these selection options allows for targeted adjustments, ensuring specific components or the entire project are centered accurately. For instance, selecting a single element within a larger design allows for its individual placement relative to the machine’s center, while selecting the entire design centers the group as a whole.
-
Interaction with User Origin
The Move tool’s behavior is directly influenced by the User Origin setting. When the User Origin is set to “Absolute Coordinates,” the Move tool’s coordinate entry relates directly to the machine’s origin, simplifying the process of centering designs. Other User Origin settings require additional calculations or adjustments to accurately position designs relative to the machine’s center. Understanding this interaction is crucial for predictable and accurate results.
The Move tools capabilities provide essential control over design placement within the LightBurn workspace.

3. Absolute Coordinates
Within LightBurn, Absolute Coordinates provide a fixed reference framework essential for locating the machine’s center. Understanding this coordinate system is crucial for precise design placement and consistent results, particularly when aiming for symmetrical layouts or aligning with pre-existing features. Absolute Coordinates represent a fixed point relative to the machine’s origin, unlike other coordinate systems that shift based on the current position or document settings.
-
Fixed Origin
The core principle of Absolute Coordinates lies in their unchanging origin point. This point, typically the bottom-left corner of the machine’s work area, serves as the reference for all coordinate measurements. Regardless of design manipulations or laser head movements, this origin remains constant, ensuring consistent and predictable positioning. For instance, the coordinate (0,0) always represents the machine’s origin in Absolute Coordinates, regardless of where the laser head is currently located or where the design is positioned on the screen.
-
Consistent Measurements
Absolute Coordinates ensure consistent distance measurements across the entire workspace. The distance between any two points, calculated using these coordinates, remains constant regardless of the design’s position or orientation. This consistency simplifies calculations and ensures precise placement relative to the machine’s center. For example, moving a design 10mm to the right in Absolute Coordinates will always result in a 10mm shift along the X-axis, regardless of the design’s starting position.
-
Machine-Specific Reference
Absolute Coordinates provide a direct reference to the physical dimensions of the laser machine’s work area. Understanding the machine’s dimensions in Absolute Coordinates allows users to calculate and utilize the center point effectively. This machine-specific reference is essential for accurately centering designs and ensuring alignment with the physical workspace.
