GCodeDemoCNC Plasma Cutter prototype

Andy Lynch wrote in to tell us of his experimental plasma cutter CNC machine. GcodeCNCDemoV2 was used in the brain of a portable CNC Plasma cutter prototype.

He says,

Thank you for your work on the Drawbot and for your openness with the code.

My mechatronics group at NYU School of Engineering relied on your code for
parsing gcode to our polargraph inspired CNC Plasma Cutter proof of
concept.

His blog post is really thorough, an excellent read. Pictures, explanations, part lists, and wiring diagrams. You can repeat his work for about $150 USD. Read it all on Andy Lynch’s personal blog.
