XY-plotter making my group's name's initials

Seen here is the prototype plotter, now fully assembled, writing the following: "PJS RMS STM" Which stands for Peter Jacob Sørensen, Ramsus Müller Smedt and Sigurd Traberg Moth, us who made this. The text is very hard to see from the camera, since the pencil only leaves a weak line, but better pictures can be seen here: http://i.imgur.com/Xh8qzlF.jpg Lined up and easier to see: http://i.imgur.com/23sfZW5.jpg Heres a scan of the paper with high contrast: http://i.imgur.com/QEZJQ6Y.jpg? 2 And heres another scan where we made it write "HANSENBERG" the name of our school: http://i.imgur.com/vkidZDX.jpg? 1
