multi-operation simulation : Part does not move ?

Hello,

I am currently working with the Shop Floor Machining app and need to machine a part in two stages: first the upper part, then the lower. I've set up two part operations, each with the correct NC assembly, stock, and design part. During the simulation of the first part operation, everything works well—the part is correctly clamped to the mill vise, as seen in the video. However, when I add the second part operation, the part no longer moves with the mill vise and the table. I’m not sure where this issue is coming from or how to fix it, especially since I’ve managed to perform both operations successfully before without encountering this problem.

If you have any ideas on how to resolve this, I would be grateful! You’ll find a video excerpt of the issue I’ve described, along with the corresponding 3DXML file, attached to this message.

Thank you!
