Rotary module with Artisan

Hi all, trying to connect the Rotary module. The doc, made for the A350, indicate to connect in Addon 2. That does not work on the Artisan, which does not have the right number of pins.
I have Motion 1 or 2 free on the controller.
Which one do I connect to?
Would be nice to have an updated installation guide.

I believe the most up to day manuals are in the wiki. I have mine connected to “motion 1” and it works great.

Thanks, I did not think about the WIKI, I should go there more often!
