How the laser cuts¶
The 'Cuts/Layers' tab determines how the laser cuts. It is located at the top-right of the screen.
In the 'Cuts/Layers' tab, you can set the most important parameters per layer:
| Parameter | Description |
|---|---|
| Mode | The mode of cutting, see below |
| Output | Run the laser here yes/no |
| Show | Show this color on the drawing |
| Air | Have air on yes/no. Have this on for cuts |
| Speed (mm/s) | The speed of the laser |
| Power Max (%) | The power of the laser |
| Pass count | How often the laser cuts each line |
Selet mode 'Line' to cut
Here are the modes:
| Mode | Description |
|---|---|
| Line | Cut through |
| Fill | Will etch the surface |
| Offset fill | Hard to describe :-) |
The pass count, speed and power differ per material.
Here is a list of know values:
| Material | Cut | Pass count | Speed (mm/sec) | Power (%) |
|---|---|---|---|---|
| None (this can be used for practicing) | None | 1 | 10 | 0 |
| Paper for oil and acryl painting, 290 g/m2 | Complete | 1 | 10 | 75 |
| Paper for oil and acryl painting, 290 g/m2 | Half | 1 | 10 | 20 |
| Paper from printer | Complete | 1 | 10 | 20 |
| Paper from printer | Half | 1 | 30 | 25 |
You will have to find out your values by trial and error. Please contribute the values for your favorite material.
Where the laser cuts¶
The laser can show where it will cut.
This laser light is safe! It is at very low power.
In the 'Laser' menu, click 'Frame' (either the square or the oval one) to see the contour of where the laser will cut:
Align the material with where the laser cuts, either by moving the material or by moving the image in LightBurn or both.
