Yes, John's preference for a precision handwheel is easy to share. :-) However, positional tracking is really only useful within a single revolution if I haven't counted my revolutions of mad winding to reach the other end, and the axis isn't tracking in real time? If excessive positional lag is allowed to accumulate on the handwheel, would it be useful to eat it all up if the wheel is reversed by 2 or 3 clicks? That could remove timeout issues, be relatively simple to implement, and provide the operator several levels of wheel use: Crank madly, to dash up the other end. Pause to let the axis catch up, when approaching the target position. Reverse while there's significant positional lag, if a stop is needed. Crank slower, to close in. (Position accurate) Reverse in absence of lag, to backtrack. (Position accurate) Being dependent only on observable handwheel and axis factors, the behaviour is perhaps easier to use than a timeout? However, for a setup jog, I'm just as happy with a jog button that starts slowly, accelerates when held down, and single steps when briefly jabbed. (I'd rather hold a button than wind like the dickens, even though I probably need the exercise.) Erik ------------------------------------------------------------------------- Take Surveys.
