I had a similar problem in my early days, I would not have known how to decode g-code back then, but yours is very random whereas as mine was consistent. I was printing architecture and every time I jumped across a window the resumed printing would produce an effect like yours; with the smaller models normally right across the front face (4 windows) until it settled down on the side walls (no windows). The areas below/above the windows were perfect. I resolved it in the end by slowing the print speed - whether or not I also played with retraction settings I do not recall.

I realized I'm probably not going to get an answer to this post because there are too many variables. So I decided to dissect the G-Code produced by Cura.
When I look at the code one layer at a time, in areas of this model, I see inconsistencies in where my print nozzle will be during the print. Another words,
if the layers are the same going up one layer at a time, printing the mirror of the last layer, why would the gcode change?
For example;
When I look at the vertical walls of this part, the have a wave in them. But the wave has a pattern in it.
When I look at the corners where windows in the cab were placed, the print quality dived. But not all along the Z axis. Only when there was
a transition in the way the previous layer had been laid down.
I guess where I don't get this is I should be seeing code that looks like a mirror, row by row when the print is the same going upwards.
Secondly, why do corners or changes in layer right angels or even small angles change the print quality unless it's the code...
Forgive me if I don't know what I'm talking about. Just trying to get good parts produced.
