Re: [CAD_CAM_EDM_DRO] Re: RE: DRO UPDATE

Terry,
You may have the same problem that I have and that is the "switch" that
needs to be set on the parallel port. Have you tried using the DRO40A.exe
program instead of the DRO40.exe??

This is documented in his text files and you may have to do that. That is
the only way I can get mine to run also.

Hope this helps, but let me know if it doesn't.
