Re: Inconsistent Layers
Looks to me as if the fillament is "cupcaking" over the previous layer.
Could be issues in Z guidance/screw-threads, is it on the same height with every print?
Could be issues with temperature/fan speed but that is unlikely to be as uniform as in the picutre.

I’m getting this same thing on my new Mini. The imperfections are always at the same Z height regardless of what I’m printing. Did you find any solutions?
RE: Inconsistent Layers
These seem to be similar to known issues slicing with Slic3r/Plicer. Try slowing down the print speed, a lot. On enable Thin Wall detection.
The artifacts tend to occur when internal geometry changes, and layer print times change by a large percentage. I've also turn down the cooling criteria so the printer prints at roughly the same speed regardless of layer times - but this is probably not recommended for all case.
