Creality K1 Max unable to produce smooth walls

I have been troubleshooting this K1 Max for like a month now and I am still unable to produce smooth vertical walls.

It doesn't matter if I use Creality Slicer with all the auto calibration settings, or if I use orca with a manually tuned filament setting.

I already replaced the extruder gear because I thought it might be inconsistent extrusion but that didn't change anything.

Does anyone else with a K1 Max also have these issues? Is this just "standard" K1 walls and there's nothing I can do? If I can't get smooth walls then this machine is basically trash to me and I am going to sell it for scrap so I need to know like... Is this worth continuing to troubleshoot or is this shit just fucked and I need to find a new printer with a large build volume?
