Hello,
I'm a bit confused, can you explain your problem clearer?
And please share also the sketch you uploaded and not only the webpage code.

your updateval function is never called

all you have in the "release" function (that is called when you relsease the mouse after you changed the dial) is a console.log.

you probably want something like this

release : function (value) {
       updateVal(value);                       
}

and the updateVal function

function updateVal(value)
{
    $.get('/arduino/knob/' + value, function(data)
    {
        console.log(data); // the response from arduino
    } 
}

ok
solved,
thank.

Maybe now, can you help me to understand the stepper motor.
I want to drive the motor as a rc car.
I have a motor shield adafruit, i was able to move the motor by a point "A" to a "B", with a slider.
Now, i would like to drive the slider "-255, 0, 255".
Where "-255" is the maximum speed to the left, "0" stop, "255", the maximum speed to the right.
I hope you understand !?
I use the "Accelstepper" library
grazie.....
