Re: [CAD_CAM_EDM_DRO] Re: Electronic Lead Screw Drive Article ?

i will say that the circuit is primo basis for a
tach/speed controller. he has 40 holes on his spindle
sensor disk that he was gonna up to 120.
we know (i'm still amazed!) that you can do threading
with turboCNC and a single index point on spindle.
his circuit didn't have indexing, nor require it to
make 2 motors run in synch. the circuit deserves a
star for precisely comprehending and solving a
problem- but i'd say, once you have tachometry, speed
control and indexing, you've got all there is to get.
then it's just a matter of resolution and how fast you
can do whatever you want with it.
