Since you posted this at my birthday, i want to make a comment
Is the sliding magnet suppose to lift up a bit so it can repel the stationary magnet when they are close to each other?
If so, and when you adjust the slide by reducing friction, you can place a spring where the slide can bounce back after repulsion. The slide magnet has dropped down to initial level at this point.
Then at this position it should not be any forces to prevent the slide to repeat the cycle (??) - just thoughts.

less than 4 grams force is applied

  Sorry I missed your post until now.

    I don't understand your question

Neither did I, LOL . I missed out something that made my question just dumb. What I asked for, was when you lift the moving magnet up, so more of south poles is facing eachother, you will get repulsion, but the moving magnet is forced down, and not neutral in the vertical plane even if it is neutral in the horizontal plane.

Yes "not neutral in the vertical plane even if it is neutral in the horizontal plane."

Force is present in the vertical direction, but.... there is no work / energy expenditure required in the vertical directions.
Only increased friction upon the sliding track system.  That force can be neutralized by utilization of dual / magnetically isolated / mechanically linked units.
