Re: [CAD_CAM_EDM_DRO] Re: faster steppers

Programming? My electronics is rusty but....as I recall from way back
when....a simple magnetic pickup to count the revs, a pulse gen ckt, a
divide by ckt and an LED DRO is all you need. In fact, I believe some of
the old Sams or ??? hobby electronics books had a number of ready made ckts
for building a tach. I lost all my books in a fire about 14 years ago so, I
can't look them up.
