Re: [CAD_CAM_EDM_DRO] Simple DRO

Scott;

You need to look at Art Eckstein's page at

http://members.surfsouth.com/~axtein/dro/dro1/index.html

Art has done just what you propose and is quite satisfied with the results.
The electronics and software are readily available for pennies from Dan
Mauch at

http://www.seanet.com/~dmauch/

Or you can use Art's software which has a few embellishments. I think
source code is provided.
