destroy & Wesen are a two person shop creating specialized music gear. As part of their recent MIDI Command development, they got into case manufacturing. They purchased a small CNC mill to cut the aluminum cases. unhappy with the software options offer [Wesen] chose to write his own G-code generator. G-code is part of the numerical control used to command CNC machines. He implemented his interpreter using the language he’s many familiar with: common Lisp (not unexpected if you notice the website’s backend). The post covers the design viewpoint used and some of the problems that came up. We look forward to future releases because the interpreter can generate milling code using processing.org sketches and cut PCBs directly from Eagle.
You may remember destroy & Wesen from when they shared their Eagle layout videos.
