Electronic Leadscrew for the New Lathe
vtsteam:
I'm not doing metric.
If you want metric it could be done the same way, but naturally you'd probably want a metric leadscrew anyway, and then you'd work the pulley and encoder ratios the same way but favoring your measurement flavor.
If you want both yeah you could go the microprocessor route. Been there done that earlier in the thread.
If I thought about it hard, I bet I could do it simply with IC's as well. 8 bits (two ls161s) gets you divisors up to 255. And 254 is an interesting number for system conversions. But I don't want to think hard about it right now.

There is actually a german version that works, and seems popular in germany.

Just use google translate :D
It's also able to do tapers and radius,

Yup, I know, mentioned earlier This thread has long since evolved into making one, though.
Ysee, if project fora like this one just carried links to manufacturer's web pages, there wouldn't be any interesting projects in them, yes?

I meant it just for inspiration, have also a link to the full forum page talking about it's working and development. It's rather interesting, but you have to know german or use translate.

Fair enough assink. But I should explain what I love - I guess you'd call it elegance in conservation of resources. So I'm real happy with ditching the microprocessor-display-multifunction approach and thinking through a pennies on the dollar four component control solution that will cut any integer thread up to 255 tpi with no cumulative error. I think of that as my kind of fun. And that's what drives me to make my kinds of things and post them on this very unique forum. :dremel: :beer:
