CircuitMill — PCB to CNC

Preview tool motion and export CNC files

Inspect PCB toolpaths in 2D or 3D, play motion at different speeds and download metric GRBL programs with a setup sheet from CircuitMill.

Inspect the planned motion

Use the 2D toolpath view or 3D motion simulation to review cutting moves, rapids, origin and holding tabs. Orbit, pan and zoom to inspect details; playback supports multiple speeds.

Estimate machining time

Motion estimates use available controller rapid limits, cached limits or profile defaults. Acceleration, communication delays and operator actions are excluded, so actual runtime can be longer.

Export or send to milling

Download individual NC files or a ZIP containing programs, a setup sheet and a manifest. Sending operations to Milling freezes their setup and locks the associated design step until completion or cancellation.

Enable JavaScript to import boards, generate toolpaths and use the milling console. PCB files are processed locally in your browser.
