Automation is not out of the question for home brew
I have made a 5 axix cnc, and retrofitted a lathe both use EMC2 software
One thought is a hacked scanner, with the motor moving the fiche
carriage instead
but its not simple to have an easy focusing on that
We could overlap scan sensors to cover the whole width and then
calibrate out sensor positions
and merge the resultant images, but that involves getting a pile of
donor hardware and loads of effort as well.
but the 2-3 k cost for simple and 10k for automatic are out of the question
Catalogue the fiche and only scan on demand is my intended method.
Probably helps to induce the odd donation too, if its an easy download
one just sees costs and effort for ones labour
