Back and forth motion in single click

[1_more_Robot]

Hi. I'm new to dynamic components.

I'm trying to model a cam motion, with a follower rod that would rise and and fall back down with a single click. For the life of me, I can't figure out how to do such a thing.

The only alternative I've been able to come up with is to have the cam do a half-rotation of 180 degrees per click so that it tracks the position of the follower rod. It's not the ideal solution.

Can anyone help? Thank you!

formula used:

did not see your post until today, after a bit of research on cams, (not my field, I'm carpenter and estimator)

need only the rotation and the formula does the rest
