Z banding on large prints?
Hi I noticed some strange banding artifacts showing up on large prints and not sure what could be causing it. Flow and PA has been calibrated for the filament and I have not noticed this on smaller prints before.

Realy curious on your sliced files. If there is a repetition in the bands, you might want to look and see in the gcode view of your slicer if there is something similar on (for example) cooling on/off, rotation (extruding clockwise vs anti-clockwise), flow, speed. I sometimes see these bands as well and can see on the gcode view for cooling fanspeed a similar patern... switching it on or off over the whole part could tell you someting?
Also, Near the corners it seems to be much better. Could this have to do with pressure advance, properly tuned (as you wrote) and that for normal extrusions you have a slight over extrusion?...

prove it to yourself, print a large vase mode item. If you have the same artifacts it is Z-banding, if not then it is a different issue

it was a combination of the model and artifacts caused by the slicer. Thank you for your guys time! @blacksmithforlife 🇺🇸 @Arthur_C
