RE: [CAD_CAM_EDM_DRO] Re: Optical mouse for DRO anyone? - not for WIRE!

Save yourself a load of work - there are loads of ROTARY industrial shaft
encoders with resolutions from 360 to 5000 pulses
per rev with TTL outputs etc on Ebay - From about 25 UK Pounds upwards.

Yes, ideas are always welcome.
Thanks for all of them. I have two things to factor in: I have perhaps
a half-dozen different cord types with differing characteristics, and
I don't have unlimited resources.

Constant tension doesn't work too well -that is how existing tools are
designed around. grip & slip may work, but will require way too much
effort. I'm leaning toward a 'no tension' solution with an ultra-light
metering wheel with a simple optical encoder made from an old mouse wheel.

Thanks for all your ideas & discussion - there is much insight in your
words, which will undoubtedly help in finding the best solution.

Tks!
CL
