Editorial interest 78/100 Selection signal · not a rating of the site

A browser-based tool that converts Gerber and KiCad PCB files into metric GRBL G-code for milling, drilling, and board cutouts.

Landing page captured for the 2026-09-18 issue.

For: PCB hobbyists and small-batch CNC fabricators
Worth noticing: It accepts ZIPs, multiple Gerber and Excellon files, or a native KiCad board, then processes them locally.

Field notes

The workflow accepts either manufacturing-file bundles or a native KiCad board, then normalizes inch-based input to millimetres. Users define material, tooling, and work origin before generating separate programs for isolation, drilling, and cutout operations. The page specifically mentions grouping holes by diameter, adding holding tabs, and previewing tool motion. Projects remain in the browser, with backup and G-code export available for use with an external sender.
