Can’t get rid of those layer problems
There are websites with print errors and tips to solve the errors, search with google.
Check if your extruder is loose, check all bolts, and lift the extruder(by hand ), push it wright -left to see if has to much play.
Check the whole printer for loose bolts - screws- grub screws.
Check if belts are not to loose, but also not to tight, if it is to tight too much pressure will built up and make your prints bad, the belts should have a little play(very little) so pressure can be released.
Make a picture on the bed, how it is printing, what is the front? x y z axis?
Did you slow down?
On the forum you can find about a line outside the model , and how to adjust this, if this is your problem i do not know.
Make a small model of your big model, in prusa slicer you can cut it, and use only the bad part of model, then testing will go faster.
Support once suggested me to use brims to avoid this issue but I don't find it useful.
the little box where the nozzle is placed is movig if i tilt it
A little is normal, check the bolts everywhere.
I had myself the extruder loose(after 1 year of use), some bolts at the back came loose.
i should check the bolts of the extruder too?
