Without photos of what you are getting, it is difficult to say, but it sounds like a loose belt.

Picture added, sorry!
I'll try with a tightened X axis, thanks for your advice!

Tightening the belt was indeed the solution, thanks Mick!

Wow, it's impressive that you were able to get results that bad with a loose belt without it failing to print entirely.

# Ender3 printing flattened on X axis
