Greetings. Great instructible! I am using the same setup minus the potentiometer. I am using a capacitive touch sensor to trigger the stepper to do a quarter turn per touch. The issues I am having is that the motor is jerky and not smooth (like in your video), also, it seems to want to ramp up and ramp down. Any suggestions as to what might be happening? Thanks.
