Well, no one answered my question about the customstepper library and it got to the 2nd page,
so ill try to open it in a new thread, if no one will answer ill probably should switch to the accelstepper library 
I was experimenting with the customstepper library & 28BYJ motor, and trying to make the motor rotate one rev. in CW direction, then one rev. in CCW. the code looks somthing like below . the problem is the first "rotate" command is being ignored, the motor goes just 1 rev in CCW then stops.
i understand there are blocking/non-blocking commands, thats why i put the delay, but still its not working like i want.
will appreciate your help understanding why this happens and how make it to work.
thanks!
