For just doing one, or just the other, it's fine.  Or if you want to do both, just not at the same time it's fine.
But as soon as you need both together the shaking becomes a serious issue.

Honestly, 99% of the time a modern smartphone is all you need for photomicrography in SMT work.  Don't buy a microscope to take photos or videos.  You almost certainly don't need it for that purpose, and it will compromise everything else.

Here’s Amscopes response.

I’ve told them to rewatch the vid with the sound on, then they will hear it knocking.

I also said that I will send two vids in the morning, the first hopefully showing better the gap opening up, and the second showing my old stand and how it didn’t open up etc.

Did something get lost there?

In your videos, I might slowly run the focus rack until it bottoms, and then back, so that they can selectively time loop a cycle.

Sorry.

According to our product manager, microscope damping grease is typically the best to use to ensure smooth operation of rack systems.  It is a type of synthetic hydrocarbon grease.  There are several on multiple marketplaces including Amazon: https://www.amazon.com/dp/B084H9CDLJ”

The PM knows his grease and, indeed, you might want to reapply some, perhaps 20 years from now. But I thought the stand is new. It is not always easy to convey the root of a problem and I think somehow it did not get through.

Something you can try is to rotate the head 90°, so that it is horizontal, remove the focus tension (friction), and then feel the loose head moving back and forth. (Be careful and makes sure the stand is well clamped.)
