Doug,

Not sure if I'm following here. CncPRO IS a S/W based CNC?!? Between
this and what?

On another note, something popped into my head when I read this post.
What if we made the HARDWARE more 'tolerant' of 'poor' pulse trains.
Isn't this at least a little of the theory behind the Gecko "pulse
multiplied" drives?

Yes, I can see how several points from recent threads apply
negatively, but:

What if we started to think like the sony Discman (portable CD
player). Which includes a "buffer" so that even tho the "bump and
grind" of carrying it caused the laser head to "skip", all we hear is
smooth uninterrupted sound!!!

NOW what we'd be looking for from the pulse train (out of the PC) is
the average rate (as determined by our hardware), correct ratios of
pulses between axes (so the interp is correct)and the correct NUMBER
of pulses!? Many servos' already implement some of this. We'd just do
the front-end, and assume the 'back end'(on steppers).

Hope this helps.
