Machine operation

The BOD2 printer allows the operator to move a printhead that extrudes the building material within 3 dimensions. The printhead moves along the X-axis (width), the X-axis moves on the two Y-axes
(length), and the whole X/Y-axes group moves up and down the four Z-columns (height). Thereby,
the gantry principle allows the printer to access any position within the printable area (PA), while
providing complete freedom of movement within the volume.
