Here is an extreme example of notches caused by the printer. They go along all sides but are the strongest on the Y faces. They also happen quite randomly sometimes they are tiny sometimes they are stong.
I have tightened the belts already and while that reduced the ghosting on the X face alot, it did nothing on the Y and actually never helped with the notces. This test cube has notces and ripples too but not that strong (the skirting on the bottom of that cube is my fault I set the bed level a little too low).
All models have been sliced with Cura and printed on Anet A8. Flow = 110%, layer high 0.1 for the first example and 0.2 for the cube, printing temperature = 195°C, no change on jerking and acceleration from default settings. Cube size = 2x2x2cm.
The printer has frame support https://www.thingiverse.com/thing:1672959 but no other upgrades yet.

I see two problems with your printer: your filament seems to overheat in some areas, and you overextrude a little. My suspicion is, that your heating behavior is not well done and it overshoots the target temperature, leading to an overcooked filament, then the temperature drops below the temperature you need, leading to a wavy pattern and brown lines.
fixing
I suggest running a PID-tune cycle to get better heating behavior.

You can see it on the top of the Y frame, there is a deeper notch. Supportmaterial also often gets underextruded at the beginning of a layer line (I have retraction off btw for that reason).
