Designing a combination roller/capstan for the telecine prototype as the mounting of current sprocket has some wobble in the mounting. Also need at least one more roller to improve film tension and frame position stability/accuracy.
Plus looking to use for SMD, 8mm and 35mm films, so have been making the scripts very easy to change through variables. The number of sprockets and size and slope, inclusion of outer guide walls and slope etc are all adjustable.
Currently revising code to improve how all the variables etc fit in to make the changes very easy – looks promising. Will release code in next few days in github spanner888 and thingiverse.
Plus still have to get out to XinCheJian and print and test, especially the shaft and sprocket fit!
