PLEAS HELP!!! Terrible printing results...

[De'Wisz]

Hallo fellow 3D printing enthusiasts !
Kindly please help with problem described below...
Suddenly, without any reason, my prints started to look terrible.
I do not recall to change anything in my Cura setup. Already have tried different filaments and speeds...
Can you recognize the problem from the attached pictures?

Hi.
If I have a problem I always check to see if the nozzle is blocked, try changing it to see.
