Hi
I have a fairly standard L298/L297 stepper motor driver board that seems to work perfectly except for one thing which I'm wondering if it's normal or not.
When I enable the drive and step the motor a kind of liquid gurgling noise emanates from the stepper motor as though the electricity was acting like water or something. Is this supposed to happen, or if not is it easily fixed? My guess is that it's something to do with the chopper in the driver board and the motor maybe not getting the right amount of current.
Thanks
