The very-first stepper-system I built was a small lathe with OLD S.E.
steppers which became supeseded by their MO92-FDO8 design. That old system
"worked", but if the programming wasn't "just right", it would do "phantom
steps" now and then. Over the years, I figured all that slowly out, and
fixed it in software, per previous suggestion.

My LATEST stepper-systems have been with the newer KML092-??? BIPOLAR
("square") motors and BIPOLAR-CHOPPER drives with Opto-Isolator inputs. 100%
PERFECT! Never any "phantom-" not "skipped-" steps at all!

I am presently building a plotter with KML061 motors and Mariss' G210 drives.
I have so far only temporarily hooked these up "on the bench" to see how
they behave, and they SEEM to be "perfect". So, I must wait until I get this
plotter done and running to make a final judgement. IF as good as the
workmanship/quality looks, I will now use the Gecko drives for ALL my
"stepper stuff" to come! There is NO question that the bipolar-chopper
system is far and away better than the old unipolar "R/L drive"!!!!!!!!
