ja I have physical dynamics on, and when i rotate either the gear or pinion, the other does not move and becomes stuck itself.(Basically one cannot move the other and they and cannot get passed the other) Physically there's nothing wrong with the setup. Gear and pinion in the correct positions...
I have a gear and pinion assembled onto their own rods. rotation of gear and pinion is correct, but they are not moving each other. What step am I missing... THANKS
