After talking to our “mechanics consultant”, Tom, we decided to redesign the stage and the stage holder so that we could use the dvd head holder that comes with the dvd head. It has some nice features that we could take advantage of, such as a cog system which could be used for coarse movement of the dvd head over the sample, and screw holes that we could fit the precision screws into. This means we don¹t need to have such a complicated design, with the old dvd head and flexure stage abandoned.
Although the laser cutter is out of action, we drew up our plans for the new box and stage with the help of our “machining consultant” , Luke. Our design includes holes for focus and tracking knobs, power cable and switch, and usb.
Tomorrow we hope to be able to cut them!
