“This instructable describes an A2 plotter made from low cost aluminium extrusion, a piece of particle board, two NEMA17 stepper motors, and a few belts and pulleys.
The plotter is:
- high resolution (80 steps/mm),
- and scaleable
The plotter has an on-board interpreter that recognizes the g-code output from “Inkscape” .
Metal work is simple … all you need is a hacksaw, three drills, a rat-tail file, and a screwdriver.”
