Hi samia908,

The first step is undoubtedly to make it move.

I have recorded a one-minute screen-capture of it:

Let’s go step by step, but I need something from your side, as I don’t know what step are you missing. I have as well only part one and two of the tutorial to go from.

I can provide an upload link. You can’t share the set up public-ally. Just let me know. (Edit: I have sent you an upload link /edit)

If you have a specific, or several questions, please refer to the tutorial time, so I can help quickly.

All the best

Hi - the tool doesn’t seem to work in R21.207 (PC). Did something change with xpresso to break it? I did get it running in R18, but would love to get it up and running in the current version.

Hi collider,

I can confirm this for R21. It needs to be updated or marked in the description as to what releases can work with it.  I checked it in R17, and all seemed to work fine. Which was a test to see if the file was OK to begin with.

I run a C.O.F.F.E.E. check, but that was not the reason, no scripts of that language were used.

Sorry about your wasted time.

Cheers

Thanks for the speedy reply. Not too big a waste of time, I can get by with R18 for now, and saves me from writing my own in xpresso (which I had started doing before I found this). If I get a free minute later this week maybe I’ll have a poke around and see if I can get it working.

You’re very welcome, collider, and thanks for understanding

Often the XPresso can be simplified for Cogwheels. You can use the number of teeth to get the rotational ratio.

Here is an (old but tested in R21) example:
https://www.amazon.com/clouddrive/share/m9XxlHFCzOUEUk9zD9iL4t1Br8pZ5Szcl6P2SY53g9L
The cogwheels are under a null, so the null can be used to adjust the fit to the previous one.

Tip: If you flip every second cogwheel: you don’t have to bother with the direction of the rotation.

My best wishes
