Body in my model moves when it shouldn't

The green ball in my model moves when it should not.

The ball is on the follower side of a prismatic joint, and the base is joint to the longitudinal axis of the red beam.

I've set the angle of the revolute joint (left side of the red beam) to be 0 at any time. Still, even when it seems that the ball doesn't move, I'm getting a value when I sense directly.

I have no idea what could be causing this error

Hi Ericko,

If you look at the vertical axis of your scope, you can see that your ball is moving roughly 2e-29 meters in 10 seconds. This is as close to zero as the precision of your computing system can represent.
