cirQWizard is a cross-platform open source software app designed to control PCB prototyping machines. It’s much more than a Gerber to GCode converter – it generates GCode, controls the machine, and guides a user through the processes of insulation milling, holes drilling, contour milling, solder paste dispensing, and SMD components placement.
