The Amazing Plotter
The machine has
movement in three different axes: A pulley and belt arrangement moves
the pen in a forward/back motion. The belt is attached to the gantry
support. A linear-track mechanism salvaged from a dot-matrix printer
allows left/right movement, and a scavanged floppy disk drive mechanism
was used to create the up/down movement of the pen.
Secure a piece of paper to the clips provided for this purpose, enter your text into the computer control software, and the plotter does the rest.
