Assignment
The initial idea was a drawing machine using two stepper motor and a fixed pen; with the ability to interpret
a gcode file and replicate a drawing in a piece of paper. We decide to use two levels for the position of the stepper motors (lower level for x-axis and
upper level for y-axis) and the pencil attached to the upper level.
The design was very simple, the construction and the results can be seen in the next pictures.
