Re: Need indexing head software....

Bob,

In the past I've put together quick & dirty I-LPT Basic programs to
do this type of thing. I was hoping not to have to spend the time to
do a full featured program, especially if someone else has already
done it.

I need something very easy to use. It has to be feature-wise as
capable as the Haas indexer box I'm replacing (that box is defunct).
Prompting for input, multi-step indexing sequences, dividing circles
into any spacing by simply specifying the number of divisions
(software does the angular/step calculations), saving of programs, a
position readout visible from at least 15 feet, interface to the CNC
controller, etc. Conceptually, all simple stuff, just takes time.

thanks,

Doug
