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, macOS and Linux. 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
