zAxis getting loose

Hi,
has anyone had the same problem that the z-Axis on the Inkspire printer is getting more and more loose?

I think it all started back then when the calibration worked a little different. Back then the printer moved the platform a couple of times with quite some force into the resin tank to calibrate the platform.

At first it wasn’t a problem, but it’s getting worse and I think that might be the reasons more and more prints fail.

Does anyone know if there’s a screw somewhere that I can tighten to get rid of the wobbling?

Here’s a video where you can see the wobbling
