Laser Settings

The Laser page in Machine Settings configures your laser head(s) and their properties.

Laser Settings

Laser Heads​

Rayforge supports machines with multiple laser heads. Each laser head has its own configuration.

Adding a Laser Head​

Click the Add Laser button to create a new laser head configuration.

Laser Head Properties​

Each laser head has the following settings:

Name​

A descriptive name for this laser head.

Examples:

  • "10W Diode"
  • "CO2 Tube"
  • "Infrared Laser"

Tool Number​

The tool index for this laser head. Used in G-code with the T command.

  • Single-head machines: Use 0
  • Multi-head machines: Assign unique numbers (0, 1, 2, etc.)

Maximum Power​

The maximum power value for your laser.

  • GRBL typical: 1000 (S0-S1000 range)
  • Some controllers: 255 (S0-S255 range)
  • Percentage mode: 100 (S0-S100 range)

This value should match your firmware's $30 setting.

Frame Power​

The power level used for framing operations (outlining without cutting).

  • Set to 0 to disable framing
  • Adjust based on your laser and material

Frame Speed​

The speed at which the laser head moves during framing. This is set per laser head, so if your machine has multiple lasers with different characteristics you can choose an appropriate speed for each one. Slower speeds make the frame path easier to follow by eye.

Focus Power​

The power level used when focus mode is enabled. Focus mode turns on the laser at low power to act as a "laser pointer" for positioning.

  • Set to 0 to disable the focus mode feature
  • Use for visual alignment and positioning
Using Focus Mode

Click the focus button (laser icon) in the toolbar to toggle focus mode. The laser will turn on at this power level, helping you see exactly where the laser is positioned. See Workpiece Positioning for more information.

Spot Size​

The physical size of your focused laser beam in millimeters.

  • Enter both X and Y dimensions
  • Most lasers have a circular spot (e.g., 0.1 x 0.1)
  • Affects engraving quality calculations
Measuring Spot Size

To measure your spot size:

  1. Fire a short pulse at low power on a test material
  2. Measure the resulting mark with calipers
  3. Use the average of multiple measurements

Cut Color​

The color used to display cutting operations for this laser in the canvas and 3D preview. This helps you visually distinguish which laser will perform each cutting operation when working with multiple laser heads.

  • Click the color swatch to open a color picker
  • Choose a color that contrasts well with your material preview
  • Default colors are assigned automatically

Raster Color​

The color used to display raster/engraving operations for this laser in the canvas and 3D preview.

  • Click the color swatch to open a color picker
  • Useful for differentiating raster operations from cuts
  • Each laser can have its own distinct raster color
Multi-Laser Workflows

When using multiple laser heads, assigning different colors to each laser makes it easy to see which operations will be performed by which laser. For example, use red for your main cutting laser and blue for a secondary engraving laser.
