Hesitant stepper motor..

Hi All,
I am fairly new to the world of Stamps. I have two or three specific
projects in mind but I’m going through the exercises first to get a grip on
things. One of the exercises is to make the Stamp operate a stepper motor
and all went well until I added to the written program and made the motor
step in a counter-clockwise direction after turning it clockwise. Yes, the
program still does what is expected but the motor seems to hesitate when
turning clockwise while it is fairly smooth in the counter-clockwise
rotation.
Is this just the way stepper motors work? I’m not referring to the
“stepping” action of the motor here, it’s more along the lines of the steps
being somewhat hesitant.
Thanks for any advice/input with this.
Bob

Bob -
A look at the program, for us, would be helpful.

What delay between pulses are you using? I don't know why it would make a
difference depending on direction of turn, but it's the only idea that
occurs to me off the top of my head. Most steppers want a delay of around
5mS minimum.
