Howz Harriet? I have fiddled with stepper-motors and home-brew machinery for
25 years, now, and, without seeing it, only reading what you say, I wonder if
you might not be STEPPING at too-fast a rate, or, not "accelerating" and
"decelerating" into/out-of your move? If the "book say" they will step OK
at, say, 400 steps/sec. without acceleration into that rate, and you start
"cold" at 400 steps/sec., the motors might-just "be surprised" before they
get moving! Try reducing the stepping-rate 25 to 50 steps/second, and re-try!

Lotsa luck! Jan Rowland, Troll
