RE: [CAD_CAM_EDM_DRO] Re: 300 IPM - machine resolution and encoder slots

Alvaro -

I think I heard that both IndexerLPT and Doug Yeager's CNCPro could output
100 kHz on a Pentium 233 or thereabouts, even during circular interpolation.
I'm pretty sure they don't expect these rates on a 50 MHz 486. These are my
first two choices for when I finally get my iron together, since they both
have lookahead capabilities, which is important at 300 IPM.
