Anyhow, the fundamentals of rotor setups are what I described earlier.
Add to a value independent of time (as in Timeline)

You might post your scene with your issue.

I did. I even get the same result manually animating. This is weird.

It might be better if you can post rotating a simple object with the setup you describe. Simply make it ramp up from 0 and maintain the same speed it achieves in the next keyframe. It's not working for anyone else, either. However, here is my scene with your Xpresso with the problem happening. I engaged Varitime, set the curve to linear and animated the clock speed from 0 to 300 over 1 second. Watch what happens at and after 1 second.

No no, in this setup you animate the VariTime parameter.

See attached file.
But again please the description of how to is still valid as
per my first post.

Cheers

Ok, yeah, that's working, you're right. You did make a lot of other changes to the other parameters, however . I can't find a "how to" doc on this so I'm a little in the dark on what all the parameters mean and do, but playing around with the VariTime parameter seems to be doing the trick. I was able to change the rotation axis from H to B in Xpresso and it worked . Baby steps . Thanks so much, Lennart, I really appreciate you and everyone's contributions. Without you guys, guys like me would be lost.

Here is a more basic rotor setup (xperTIME is really a loop tool)
It's RPM based but you can change it to degrees is the formula node i.e..

In this one you actually animate the RPM value.

Oh, that's beautiful. One issue, is I need to control Rotation B and not H. If I change the input node from H to B in Xpresso it doesn't seem to be working?

Set the "sending" object to that parameter as well.
You mustt use the same value for the object for things to work.

Cheers

I did it!

I can usually do these things if someone just "starts my orange for me" in Xpresso.

Thanks again, this is awesome!

I would again like to say that I think in most situations where people need a motor, a simple motor like this is what people want.

Cheers!
