G-code Dialect Support

Rayforge supports multiple G-code dialects to work with different controller firmware.

Supported Dialects​

Rayforge currently supports these G-code dialects:

DialectFirmwareCommon UseStatus
GRBL (universal)GRBL 1.1+Diode lasers, hobby CNC Primary, fully supported
GRBL (no Z axis)GRBL 1.1+2D laser cutters without Z Optimized variant
GRBL Dynamic (Depth-Aware)GRBL 1.1+Depth-Aware laser engraving Recommended for dynamic power
GRBL Dynamic (no Z axis)GRBL 1.1+Depth-Aware laser engraving Optimized variant
SmoothiewareSmoothiewareLaser cutters, CNC Experimental
MarlinMarlin 2.0+3D printers with laser Experimental
Recommended Dialects

GRBL (universal) is the most tested and recommended dialect for standard laser applications.

**GRBL Dynamic (Depth-Aware)** is recommended for Depth-Aware laser engraving where power varies during cuts (e.g., variable depth engraving).

Creating a Custom Dialect​

To create a custom G-code dialect based on a built-in dialect:

  1. Open Machine Settings → G-code Dialect
  2. Click the Copy icon on a built-in dialect to create a new custom dialect
  3. Edit the dialect settings as needed
  4. Save your custom dialect

Custom dialects are stored in your configuration directory and can be shared.
