Re: [CAD_CAM_EDM_DRO] wish list, case histories

I am interested in your DRO idea. I am an electronics hardware/software
guy, who lurks here as I have an interest in building a CNC rig for drilling
cases and PCBs. If you were to fit each axis with a rotary shaft encloder,
and use the home switches to reset the count to zero initially then you
could probably get a pretty accurate location. Modular is no prob, just add
another encoder. Fit the PIC with an LCD and there is all your information.
Or have three/four seperate LED displays for a bigger brighter / easier to
read display.

Hmm. Interesting project.. Let me think about it. Anyone else interested ?
