You sure this isn’t some sort of flow issue? The z-axis should be judged based on measurements of the cube if I’m not mistaken (20mm cube = 20mm) while the look of the print is dependent on speed/flow/layer height/plastic quality. The extrusion looks pretty inconsistent, and I see a ton of ringing even without anything immediately near by to cause it (you can see it across the entire width below the little slashes from corner to corner).
I dunno what firmware you’re using, but with klipper, resonance compensation and input shaping can help eliminate things like this.

It might be a flow issue. I recently discovered that my hot end was coming apart, which was leading to some print inconsistencies. This is my first print after fixing that, and swapping extruder gears while I was in there. I’ll have to check my belts and take another pass through Ellis’s tuning guide.
I am running klipper, and even have an accelerometer mounted to my tool head, but haven’t taken the time to put some temporary wiring in place to test/tune it. I’ll also have to do that. I do see some fine/faint ringing in the parts.
As for these prints, they were printed fairly quickly on a 0.4mm nozzle with 0.2mm layer height in Polymaker ASA.
