Hi, new here and new to the 3D printing world. Just assembled my creality ender 3 pro and did my first prints. A problem I had was that the thread was wobbly/wavy instead of straight in some layers. Followed the instructions from the maker and by a youtuber. Also did a leveling test print which looked ok.

Any ideas of the reason to why the thread turned out this wobbly?
Nozzle: 0,4 mm
nozzle temp 200 C
bed temp: 60 C
wall layers: 3
layer thickness: 0,2 mm

one factor is room temperature it?s lower than a normal indoor temperature. It?s like 10-12 C instead of ~20 C. Not sure if this can play a part.

it?s printed upside down, so first image is in the beginning of the print, second is in the end
