Interesting observation (or maybe not)

I don't know if this is real or imagined, but it seems that when doing solid infill or bottom/top layers, the layers themselves tend to be smoother when laid down from front right to rear left versus the other way around. It seems like there is less stringing also.

Like I said, this could be imagined, but I am wondering if anyone else have noticed quirks like this or others unexplained phenomena.

 

Brand new hotend, but it could be askew by a fraction of a degree.

 

We've definitely had reports of hotends that are askew by a bit. I could see that causing what you are describing.
I've gotten the impression that it doesn't bother people much, but if it bothers you, you may want to take it apart and adjust.

 

As I have told others, it isn't a micron precise machine, so it really doesn't bother me but it was interesting to observe, and we are talking a fraction of a degree here.
