All the screws are tightened and one is against the flat side. 
The smooth rods are in good condition. Sure not as new but good

Trapezoid nut I was talking about

I don't see any prior mentioning of the trapezoid nut in your previous posts, so this picture was out of context. Again, I'd check the grub screws, which I mentioned before and Joan posted pictures of.

@fuchsr This was my previous photo.

I’m thinking about this don’t-know-how-it’s-called, that lets the head move up and down on the Z axis… Maybe it’s ruined

the POM nut on the lead screw?

(Black thingie)

 

Yes exactly. Is it possible that if it’s ruined it causes that layers? 

RE: Weird layers alignment

Sure. Could be. Also, the screws on this one should not be as tight as other screws but a bit loose.

RE: Weird layers alignment

Oh, why shouldn’t be tight?
