Free tool
Drop in a laser cut file and see, rule by rule, whether it will cut cleanly: open paths, double cuts, loose pieces, bridges under 1.5 mm, holes under 1 mm, layer colours and units. Free, no sign-up, and your file never leaves your browser.
Made for flat pieces (ornaments, tags, signs) cut from 3 mm plywood or acrylic on Glowforge, xTool or LightBurn. It reads the usual colour convention: red #FF0000 stroke = cut, blue #0000FF stroke = score, black fill = engrave.

MocMakes files on Etsy are run through these same rules before they are listed, so you can skip the clean-up and go straight to cutting.
MocMakes on EtsyOccasional short emails from Mộc: cut-file mistakes worth avoiding, what the checker finds most often, new free tools. Just an email address; Mộc never sells or shares it. Reply to any email to be removed.

Your file never leaves your browser. The checker is JavaScript running on your device: nothing is uploaded, stored or sent anywhere.
A software check does not replace a test cut. It cannot see your material, kerf, power and speed, or how the piece looks once cut. Cut a small test first.
