Built by a real maker

A decade of hot-wire foam cutting, now free in your browser

cncfoam isn't a faceless brand. It's built by Pete Scheepens — the maker who designed FoamCube in 2014, ran a successful Kickstarter in 2015, and shipped CNC hot-wire machines to makers around the world.

Experience you can't fake

Hot-wire kerf, wire tension, temperature behaviour, rotary indexing — you don't learn these from a spec sheet. You learn them by building machines, shipping them, and fixing what breaks. cncfoam's defaults, generators and toolpaths come from someone who has done exactly that for ten years.
