Mr. Gusset is a free, browser-based conversational G-code generator for plasma cutting square and round tube profiles. Enter your tube dimensions — side lengths, corner radius, or tube OD — along with feedrate and pierce delay, then add cut operations like slots, holes, notches, and cope cuts to generate ready-to-run G-code. No CAD software required.
