Z-Banding? Not sure.
I really appreciate the community help with understanding how to level the bed and the glass/glue stick method. Helped a lot. I recently printed a benchy and xyz cube and I'm not sure how to interpret the results. I can't tell if this is z banding or right. I appreciate the help. Rather know before going down the mod territory.

Everyone will say 'yes' but more often than not it is over extrusion. Not much but enough to make layers ripple on the ends. The prints look good so you are on the right track but take very small steps when trying to fix the issue and you will sort it out pretty quick, just dont jump on the 'mod it now' wagon...at least not until you have tackled the other and more minor issues that can cause quality problems. So...if you are using 100% extrusion try using 98% with the exact same settings and see how it looks. Keep taking it down until your cube is undersized or if obvious under extrusion relics start to show up. But never underestimate the power of a percent or two of extrusion when it comes to quality. A tiny change matters and you will even need a 1-2% change of extrusion with the same filament that is simply a different color. The tiny things matter a lot.
ETA: Print it again but with 97% flow instead of 100% and see what it does. But dont assume anything until you are certain that the issues are not slicer related. Or at least that you cant overcome issues with a few slicer tweaks.
Agreed that Z-banding is sorta a BS catch-all for a bunch of easy issues. (... to which modding is not usually the answer.)
Also, run the PID autotune procedure every time you change your hotend or the cooling on it. Quite often fluctuations in the layer lines are caused by the hotend temperature oscillating.
The top layers look a bit thick. I use 95% as my baseline for PLA. Also, silver filaments are visually less forgiving and readily show flaws.
I appreciate the suggestion. Going to try to print with that setting. Ran into a problem where the extruder temperature kept climbing and not updating on the screen. Looked away for a bit and suddenly a little smoke and burning smell. :/
