Twenty-six plywood parts, labeled A-Z, are used to assemble the machine along with the customary precision rods, stepper motors, and router assembly. The bill of materials prices the unit at $458.18. The plywood structure can be milled in less than one hour, and complete assembly takes about 2-3 hours.
Pcb-gcode lets you use your milling machine, router, engraver, etc. to make printed circuit boards without using toxic chemicals. You create your design with Eagle, then use pcb-gcode to create g-code, which you run on your machine. Your machine cuts around the traces for the circuits. pcb-gcode also creates drill files to drill holes, mill files to cut the board out, or make cutouts in the board. You can also create files to engrave text on the boards, such as your copyright, component names, etc. Did I mention it is free?

CamBam is a value packed CAM software solution whose primary benefits are price/performance ratio, intuitive use, and stability. Overall we were VERY pleased with the product and surprised at how easy it was to use. The software package is deceptively robust and sophisticated….Attention to detail (ie. intelligent defaults and organization in menus) is noticed and appreciated.
