Re: [CAD_CAM_EDM_DRO] RE: CPNC and the BOX

Carlos, well our first missionary died quickly(Hoyt),
but heck , give it a try. I do not see anybody in this
group using IndexerLPT, probably because you have
to program your own GUI.

First of all, hats off to guys like Ron Ginger and Kelly (of KCAM - is he
on
the list? http://www.kellyware.com) who are spending what I imagine to be
countless hours on WINDOWS-based cnc control software for guys like us.

Secondly, I 100% agree that the realtime control of the motors should be
handled by a separate "box". So, my question is, how much are we willing
to
PAY for this separate "box"? And, how much would you expect for Flashcut
to
charge for their box alone? They sell the box WITH their software for
$1100. Would we pay $550 for the box? Or maybe $350?...

And finally, (I'm trying to pick my words carefully, and no, I honestly
don't have a financial interest in them)... what can the Flashcut box do
that the IndexerLPT (http://www.abilitysystems.com) driver software "box"
can't do better?
--- They claim "realtime" control (since it's a driver at the DOS level?)
--- They blow the pants off of Flashcut as far as steprate output (7300 Hz
vs. 100,000+ Hz)
--- They are a purely software solution...upgradeable & non-fryable
--- They are already have an open protocol and programming interface

My point is, we'll have to pay SOMETHING for the "box". Will it be less
than the $275 cost of IndexerLPT, AND, will it be any better?

I know I've harped on about IndexerLPT quite a bit on this list. So I've
kept pretty quiet about it for a while. I couldn't help myself this time.
Funny, I almost feel like I've become a missionary for Indexer.
