I've downloaded D. Kohfeld's Inventor files - Outstanding work as ever.
When I tried to animate the existing movements, I didn't succeed until now. I found a strange central shaft, that I don't understand. See picture, it's the highlighted part.
Below is another pic, that's showing an isolated section.
Function: Tan part is driven, and is fixed with the black vertical shaft. But the five parts above (Dark grey - Light grey - Red - Light grey - Dark grey) rotate freely around the vertical shaft; no torque can be transferred.
I've compared with the manual (Step 147, 148 and 151). It's the same situation.
The vertical placement of the top gear with the one to the left is not logical, too.
Thanks for thoughts
