How It Works
From idea to finished piece in three steps
1Design Your Project
Use templates, draw shapes, add text, or import your own files. Easel's tools make design accessible to everyone.
2Generate Toolpaths
Set your material, choose your bit, and Easel calculates optimal feeds, speeds, and cutting depths automatically.
3Carve
How your machine connects depends on its controller. GRBL and FluidNC machines carve live from Easel over USB or a Chromium browser; others, including grblHAL, ESP32-GRBL, and non-GRBL controllers, export G-code to run on the machine's own software. Each machine below shows exactly how it connects.
