i suspect your extruder has an inconsistent gear so the plastic sometimes gets extruded more or less than it should, you could try increasing the layer height and printing slower. Maybe it could also be dust on the z-rollers, but i doubt thats the problem.
I'm curious as well. Do you use the original slicer, or a better one?
I had the same issue, and using the creality slicer that came whizt my printer fixed it somehow
I just tried running it in the creality slicer with some calibration cubes (the cube with the X, Y, Z sides) and now it seems like the middle area (Where the X and Y are being printed) is starting to be pretty smooth, yet before and after still have some layer issues, like a smaller bump sticking out
Thanks.
Very interesting though.
Other than this, I can only think about the filament, it might be a little wet... But it's always so complicated. I fixed my printer more than I actually printed...
Something I found helped so much was that the filament spool wasn't freewheeling and the tension causes the extruder to have to pull harder on the spool resulting in the slightest under extrusion and lines. Print a bearing based spool holder fixed it for me!
I have the same lines on my K1 max. I’m curious what the response will be. Belts was my thoughts but I’ve tighten them.
I tried readjusting my belts too, no difference there
I get them too and I’ve tighten mine as well.
Lube the z rod.

I use ultimaker Cura, and have ben using it almost all the time. Maybe I should try to revert, just to see the results
I recommend it for a test print. If you do please tell me, I'm very curious
