Re: [CAD_CAM_EDM_DRO] PIC DRO

I have in my hand an encoder from USDigital with a 5/8" bore 2000 lines per rev with index $22.00

Terry.

What would you use for a shaft encoder that would be somewhat
universal? There may be no way to fit full size machines as well as
tabletop machines. Also, a shaft encoder cannot manage the backlash,
so your resolution will be no better than the current lash in the
lead screw, right?

Bryan,
I'd opt for a hollow shaft encoder. Something like a 5/8" bore. Then, all
you need to do is turn a split bushing to adapt to whatever shaft size you
may need. Only snag is, the hollow shaft units are much more expensive. And
larger.
As far as regular shafted encoders, <A HREF="www.automationdirect.com">autom
ationdirect.com</A> had some industrial units for under a $100.
