Running a Cutting & Engraving Job
Students will execute a complete laser cutting and engraving job using correct power and speed settings for each layer.
Prepare & Verify Your Design
- Open your project in LightBurn and verify all vector (Line) and raster (Image) layers are present.
- Confirm layers correspond to the correct operation: layers for cuts are labeled "Line" and layers for etches are labeled "Image"
- Use the Frame tool (F) to preview the laser path around your material boundaries.
Assign Power & Speed Settings
- Double‑click each layer in the Cuts / Layers panel to open the Cut Settings Editor.
- For Line layers (cuts), set:
- Power %: 40–100% depending on material thickness
- Speed: 5–20 mm/s for clean cuts
- Passes: 1–3 for thick materials
- For Image layers (etches), set:
- DPI: 300–500 for fine detail
- Power %: 10–30% for engraving
- Image Mode: Dither or Grayscale based on desired texture
- Click OK to save each layer’s settings.
Preview & Order Operations
- Select Preview to simulate the job and confirm layer order (etch before cut to avoid scorching edges).
- Adjust sequencing if needed by dragging layers up/down in the panel or by setting the Cut Order options.
Execute the Job
- Ensure ventilation, chiller, and air assist are on.
- Click Start in the Laser Control panel to begin the job.
- Monitor the cut/etch progress through the viewing window; be ready to press Pause or Stop if issues arise.
- Record actual settings and outcomes in your log for future reference.
Tip: Always run a small test pattern on a scrap piece to validate your settings before committing to valuable material.
