Atomstack A70 Max - Z axis problem

Hello everyone,

I’m new to laser machines and recently received my A70 laser. It’s a great machine, but I’ve encountered an issue with the Z-axis.

I think that the top end on the metallic bars on the Z-axis are loose, and I suspect a stabilizer or something might be missing. During the auto-focus step, there’s a strange noise that I believe is related to this issue. I did add some silicone spray to smooth it, and it did, but i think it is not suppose to act this way.

Has anyone experienced a similar problem or have any suggestions on how to fix it? I’ve attached a link from my google drive with some videos to demonstrate the issue.

Thanks in advance!

I came across this video. Does anybody know if it is something similar? I don’t want to risk damaging the machine for nothing.
