If you want a graduated wheel then you have to turn it slow enough that the machine can keep up. There isn't any real way round this. Even expensive industrial machines have this limit. However with their very high rapid speeds you can't spin the wheel fast enough to have a problem. One way round the problem is to use velocity mode. This simply measures how fast you are turning the wheel and sets the jog speed to be equivalent to it. The faster you turn the wheel the faster the machine moves. If you suddenly stop turning the wheel the machine will stop moving as quickly as it can. The disadvantage is that one division on your wheel will very likely not equal one unit of movement on the machine.
Going back to Jon's initial post, his machine is capable of moving fast enough but it's maximum speed is being limited by the jog override. This IMHO is a bug, or at least an undesirable feature.
