The short answer
Diode lasers from xTool's D-series, Ortur, Atomstack, Sculpfun, Creality Falcon, Twotrees, Longer, NEJE and many others run GRBL-compatible controllers and connect over USB, so one program can drive all of them. On Windows, LaserGRBL is free and capable for control. LightBurn is the paid all-rounder on Windows and macOS. Vextrify runs on macOS and Windows, drives the laser with framing, dry run and live control, and builds in photo, background, vector and relief preparation.
- Most diode lasers speak GRBL over USB
- Free on Windows → LaserGRBL
- Mac + Windows with prep built in → Vextrify
