A handful of nice cnc cutting machine photos I discovered:

Testing toolchain: LibreCAD (a QCAD fork, where QCAD is an AutoCAD copy) for generating the shape to ludicrous accuracy, then imported into Inkscape as a .dxf, then run through the gcodetools extension of Inkscape to generate the gcode file, and then run on the mill. It is a lot more laborious than that sounds: LibreCAD is on a virtual machine, the version of inkscape with gcodetools installed (wihch isn’t totally trivial) is on the host machine, and the CNC controller is an completely various machine that is not connected to anything, requiring one particular email and a single sneakernet with USB to get the final file machined. This is cut .010" deep in 6061 aluminum with a ball-finish mill, since that’s what was practical at the time.
