How It Works

From idea to finished piece in three steps

Design Your Project

Use templates, draw shapes, add text, or import your own files. Easel's tools make design accessible to everyone.

Generate Toolpaths

Set your material, choose your bit, and Easel calculates optimal feeds, speeds, and cutting depths automatically.

Carve

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.
