Convert PCB designs into CNC toolpaths
Convert Gerber and KiCad PCB files into metric GRBL G-code in your browser. Plan copper isolation, drilling and board cutout with CircuitMill.
Import Gerber or KiCad files
Start with a ZIP of manufacturing files, select multiple Gerber and Excellon files, or open a native .kicad_pcb board. CircuitMill processes files locally in your browser and converts inch-based input to millimetres.
Plan each machining operation
Choose your board material, tools and work origin. Generate isolation paths, group drill holes by diameter, add holding tabs to the cutout and inspect the tool motion before exporting separate GRBL programs.
Work locally, continue later
Your board and machining setup are saved in this browser. No account, server upload or desktop installation is required. You can export project backups and G-code for an external sender.
