A LightBurn device profile should be released only after machine identity, work area, origin behavior, units, motion direction, homing assumptions, and a low-power boundary test agree with the physical TwoTrees laser.
Confirm the Exact Model and Supported Connection
Identify the TwoTrees model, controller, firmware, connection type, working dimensions, and current LightBurn support before creating a device. Back up controller settings where supported and do not import a profile from a visually similar machine.
Install Drivers and Establish a Stable Link
Install required drivers only from official or approved sources, use the documented port and power sequence, and confirm that the operating system sees the expected device. Resolve repeated disconnects before any test involving laser output.
Create the Device Profile From Verified Values
Enter or import the documented controller type, work area, origin convention, homing behavior, and connection details. A successful connection proves communication only; it does not prove scale, direction, or coordinate behavior.

Verify Origin, Axis Direction, and Limits
Keep the head over clear space and use small controlled jogs according to the manual. Confirm positive axis directions, home behavior, limit response, displayed coordinates, and work-origin behavior. Stop if motion approaches a frame limit unexpectedly.
Run a Non-Processing Framing Test
Create a known-size square near the verified center of the work area and frame it with output off or in the documented non-processing mode. Confirm scale, direction, origin, and every boundary before using approved stock for an attended material test.
Back Up the Working Configuration
Save the device profile, supported controller backup, LightBurn version, connection details, origin method, focus procedure, and known-good framing file. Recheck connection, direction, limits, and framing after software, firmware, computer, or profile changes.
Stop and Escalate Unresolved Behavior
Do not bypass alarms or edit hidden parameters when communication, homing, axis direction, limit behavior, laser-enable state, or framing remains uncertain. Record the model, firmware, profile, connection, observed behavior, and alarm, then return to current TwoTrees and LightBurn documentation or official support.
Questions About Verify a LightBurn Device Profile Before Running a TwoTrees Laser
Which LightBurn device should I choose for a TwoTrees laser?
Choose only after confirming the exact model, controller, firmware, connection type, and current TwoTrees and LightBurn instructions.
Why does my TwoTrees laser jog in the wrong direction in LightBurn?
The device profile, origin convention, or controller configuration may not match the machine. Stop and verify these items before any powered boundary test.
How can I test a new LightBurn profile without engraving?
Use a small known-size shape in the verified center area and frame it with laser output off or at the documented non-processing mode.
What should I back up after LightBurn setup works?
Save the device profile, controller backup where supported, software version, connection details, origin method, focus procedure, and known-good framing file.
