Camera Systems & Lightburn Camera
A camera mounted above your laser bed transforms alignment from "manual jog and frame" into "drag the design over the camera image." Especially powerful for one-off custom orders where the part is irregular or the placement is critical.
What a camera enables
- Visual alignment: drag your design over a live camera view of the bed in Lightburn.
- Background image overlay: see exactly where your design will land on the material.
- Auto-trace from camera: capture an image of an existing object, trace it as a vector, engrave on it.
- Repeat alignment: for jigs, the camera shows whether the part is positioned correctly.
- Production speed: no more "frame the design, jog the head, frame again" cycle.
Lightburn Camera: the official option
Lightburn sells branded USB cameras designed to work with their software:
- 5MP camera: for medium beds (12-24"). $80-100.
- 8MP camera: for larger beds (24-48"). $120-150.
- Mounting: ceiling-mounted above the bed, looking straight down.
- Calibration: Lightburn has a wizard. Print a calibration target, mount camera, run wizard.
DIY camera setup ($30-80)
Any USB webcam can work with Lightburn:
- Logitech C270 / C920 ($30-80), well-supported, decent resolution.
- 1080p USB camera with manual focus from Amazon, ~$30. Cheaper but variable quality.
- Mounting bracket: 3D-printed or aluminum, attached to laser cabinet.
- Cable run: keep USB short (under 6 feet) or use active extender.
Camera positioning
- Centered above bed: minimizes parallax / distortion.
- Lens looking straight down: perpendicular to bed surface.
- Distance: camera should see the entire bed. Typical: 2-3× bed dimension above. (For a 400×400mm bed: ~600-800mm camera height.)
- Inside the cabinet for enclosed lasers (CO2). External / arm-mounted for open-frame diodes.
- Lighting: consistent overhead lighting required for camera to read the bed clearly. Add LED strips inside the cabinet.
Calibration: Lightburn's wizard
- Print Lightburn's calibration target on paper. Tape to bed.
- Lightburn → Tools → Calibrate Camera Lens.
- Wizard captures multiple images of the target at different positions.
- Lightburn computes lens correction profile.
- Save calibration for the camera + machine combo.
- Repeat: Calibrate Camera Alignment, aligns camera coordinates to laser coordinates.
- Run a calibration test: place a known shape, click "Update Camera Background," verify alignment matches reality.
Production workflow with camera
- Place material on bed.
- Click "Update Camera Background" in Lightburn, captures current bed image.
- Drag your design over the camera image to position visually.
- Frame to verify (laser red-dot should match your visual placement).
- Run.
- For batch / repeat: hit Update Camera Background after each part is loaded.
Auto-trace from camera
Lightburn can trace shapes from camera images:
- Place an existing object on the bed (e.g., a custom-shaped wood blank).
- Update camera background.
- Right-click the camera image → Trace Image.
- Adjust threshold; Lightburn generates vector outline.
- Use the traced outline as a cut path or alignment reference.
Common camera issues
- Distorted edges: wide-angle lens (fish-eye effect). Lightburn correction helps but isn't perfect. Use camera with narrower FOV.
- Bed not visible: camera too low or off-center. Re-mount.
- Background updates show "old" image: material was moved between capture and run. Always update right before framing.
- Calibration drifts after machine moves: re-calibrate if you move the laser cabinet.
- Color rendering is off: camera white balance issue. Lightburn doesn't care for vector workflows; matters for color marking visualization.
Premium camera options
- xTool S1 + camera bundle: built-in camera, factory calibrated.
- Glowforge built-in camera: proprietary; doesn't work with Lightburn.
- OneLaser XRF + camera: included on some configs.
- Aeon / Thunder cabinet with camera options, available factory or aftermarket.
