“This instructable describes an A4 plotter made from four plastic rulers , two NEMA17 stepping motors, and an SG90 servo pen-lift. The plotting area may be scaled to any size by increasing the length of each arm. The plotter has an on-board interpreter that recognizes the g-code output from “Inkscape”. Construction is simple. All you need is a wood saw, three twist drills, a screw-driver, a “rat-tail” file, and a soldering iron. While the software only supports point-to-point plotting, the plotter resolution and accuracy is more than sufficient for its intended purpose of creating water-color outlines.”
