## What it is
LaserGRBL is a free, open-source Windows GUI for controlling GRBL-based laser cutters and engravers. It converts images (raster, vector, SVG) into G-code and streams jobs to the machine with preview, jogging, and power/speed overrides.

## Use cases
- engrave images and logos on a laser engraver
- convert jpg or bmp images to gcode for laser cutting
- control a GRBL-based laser engraver from Windows
- vectorize images for laser engraving
- preview and run gcode cutting jobs
- jog and home a grbl machine with feed overrides

## When to choose
- you have a hobbyist GRBL v0.9/v1.1 laser engraver and a Windows PC
- you want a free alternative to LightBurn or T2Laser for image engraving
- you need raster-to-gcode conversion with grayscale, dithering, or vectorization

## When to avoid
- you need native macOS or Linux support (only via Wine/virtual machine)
- your machine does not use GRBL firmware
- you need laser power modulation features without an S-command-capable engraver

## Facets
- artifact type: application
- maturity: active
