Plot, Cut, Drill, Mill and Laser with the Z99 This book covers the construction, hardware, software, and operation of the Z99 – CNC machine. This is a multifunctional 4-axis machine for home construction. The capabilities of the Z99 machine include: large-format schematic plotting PCB plotting with etch-resist pens schematic plotting with conductive-ink pens letter cutting out of vinyl paper cutting PCB/substrate drilling PCB/substrate milling text milling laser engraving laser cutting of solder paste masks By making the support software available as freeware, readers of the book are challenged and encouraged to develop new applications for the Z99. The machine would not be of much use if the user has no option to create suitable files for the designs in mind. A large part of this book is dedicated to creating source files in a variety of freeware software packages, including Inkscape, DesignSpark PCB, KiCad, and FlatCAM. The book is also useful for readers keen to comprehend and then master the basic structure of HPGL, Gerber, Drill, and G-code files, as well as to have a go at deciphering them using software.
