Hi All, Recently, I worked on a homemade drum plotter to expose negative acting film. I added some photos under Photo Albums > Drum_Plotter_V_Sahin and there is also a video on youtube (http://www.youtube.com/user/vulcanmicronics). Later, I will add more videos. Short performance summary of the plotter Resolution 832x2032 dpi Optimum exposure time on RLN-4 Film=9.5 microseconds with 405nm 150mW laser. Optimum drum speed:~615 rpm Thanks, Volkan
