Wobble troubles on Prusa i3 MK3S

Hello Team,

It's my first prusa printer, and I finished last week to mount and set it.

From now on, I print some objects from Thingiverse to test the quality of this printer.

At the beginning, I was really impressed by the quality, but now I am a little bit more critic on the print quality.

I tried the mini octopus and it was a success in terms of Print In Place, but I think I have some under extrusion (I think it is) on the top of the head (See on the attached picture)

Moreover, with the 3D benchy torture test, I noticed that I have some wobble behavior. but not under extrusion.

I need some help from your experience to solve this kind of noisy troubles.

Do you have an idea ?

For the wobble, I was thinking that the printer is on a cheap IKEA table... and maybe with the vibration, it could lead to wobble.. What do you think ? (See picture of my setup).

For the under extrusion, to be honest, I don't know. I use the brand new filament coming from Prusa Research.

Thanks in advance, and please feel free to share any advice, or anything else which could be constructive.

My printer is on a rather solid wood table, and I had to add rubber bumpers (rubber furniture feet) between the wall and the table to reduce the shimmy.

The layering at the top of the model is simply showing the printer layer resolution. To reduce the "steps" you see, increase layer resolution by decreasing layer height. More layers make better top surface curves.  Have a look at the drawing below.
