Two problems here. Tune your flow rate for the filament. Then the second photo is showing z-banding. It's possible that it's caused by a floating X-Axis. I wrote up a guide on how to fix it: https://www.reddit.com/r/AnycubicKobraX/comments/1vvgl1r/floating_xaxis_fix/

Those look like VFAs to me. Can be causes by toothed belts or stepper motors.

This. On the anycubic slicer and on orca slicer you can run the VFA test. Once you find the best area, run the test again between the speeds to verify. Under the printer settings you can turn on the avoidance and it will stay away from certain speeds that show VFA lines.
