In this blog I am going to show you my improvements on the first version of my laser plotter (here).
I had to change the mechanics because when I tried to plot very tiny structures I experienced inaccuracies. Rectangles were not closed or one path was longer than it was supposed to. For bigger structures (2 cm) I barely noticed it. Usually these were made for fun or art and do not had to be that precise.
I designed a new mechanic to achieve less wobbling of the laser during movements and more precise point-to-point movements.
