This was the first idea:
Take apart an old printer and using one part to lift the page and the another part to rotate and flip it, in order to turn the page.
After adding the motors and testing actually you don’t need the second part… So I was thinking of using the configuration shown in the video – this would also work for my white book which is square…so I can print on A3 and the rolling bar ( not sure what to call it) can sit on the extra white. What do you think?
I still need to make a nice base for it and tweak it ..
