you are probably using 'position mode' jogging (it's default)
There are two ways to set up jogging.
one is position mode
one is velocity mode
In position mode EMC will move the axis exactly to
where you asked it to go, based on position.
It will do this even if you stop moving the jog wheel.
That can happen it you can turn the handle faster then the machine
can move the axis ( we will call that wind-up)
In velocity mode the axis will jog until you stop moving
the jog wheel.
to get velocity mode set this pin true:
axis.N.jog-vel-mode (where N is the number of the axis you want eg 0 is X)
eg in your HAL file
setp axis.0.jog-vel-mode true (don't forget the other axis too)
Hope that helps.
