Joysticks Laggy/Jerky

[TheBigCheese]

We have been experiencing a problem with our joysticks where the response seems to be laggy or almost deadbanded. Sometimes it will work as expected, but most of the time, it doesn't register until past 1/3 of the way forward or back. I've been able to have it not register until the joystick is fully forward, by moving is slowly.

It doesn't seem to be a problem with the joysticks themselves as we've tried different models and are experiencing the same problems.

Has anyone else experienced this, or does anyone have any suggestions as to what the problem may be?

Thanks in advance.
