I made a ball rolling down from a spiral slide but how to made the return path up to the top position?
Here is my sketch:

I made a modificaton on this, can anyone tell me why the ball path is not a perfect circle?

it probably is in CAD, although the resolution it's rendered at may make it seem like it isn't on the screen.
Aren't all of these tags supposed to be aligned? Seems like some are ahead in the timeline

Those tags supposed to be aligned, however I found that when I set the 2 time lines at 90 degree out of phase, the shape of the wave form does not match. (see below capture)
Therefore, I can only keep the same waveform by shifting the tags by 1 duration.
Are there any better way to solve this?
Just found that there is a "Strength(%)" parameter under Revolute type, after I changed it to 18%, problem solved, {^_^}/
( default value = 30%, cannot form a perfect circle! )

My next step is to make the red ball passing through the transparent tubes …..
@yip_cm … this is not an answer to your animation question, but your idea got me thinking about the overall design. I decided to give a go at modeling this…just for the heck of it.
