Grumpy_Mike:
I have a few Opto-endstops, "optical interrupter's" and would like to use them along with my mill to make a nice Encoder for a Lathe Spindle.
I am not sure you can do this.
Do you need to detect the motion in two directions or just one.
One is easy you just count the number of pulses, maybe even with an interrupt.
To what purpose do you want to put the count information you get?
I'd only need one direction to start, really just something simple.
I want the count for threading, the lathe I'm thinking about adding this to is a "Unimat-3" either that or I build something.
So I'm probably safe assuming that there is much more to the circuit, but for the purpose of learning and "re-inventing the wheel" I'm just looking for a simple .dxf of an encoder wheel maybe 100mm in dia, and a simple sketch for the Opto-interupter.
Thanks again for any and all help.
