Re: [CAD_CAM_EDM_DRO] Poor Man's Digital Read Out

Hi,
On Steve's page, you will find a link (outdated) to my version of his
program and interface. I have made some changes to the interface and minor
modifications to the program. The program was then re-written by Robert
Duncan to include an (semi)automatic calibration routine and a new
interface. With version 5.1, there is also a great LARGE GRAPHIC readout on
the computer screen and the interface to drive it is only 4 ICs and some
resistors. You can see how I implemented this (with updates to allow a 2:1
mechanical advantage) starting at:

There are additional pages showing how it was also implemented on a 12
Atlas lathe.

As always, I will attempt to answer any questions.At 12:57 PM 10/23/02
