wavy, artifact and layer shift

Hello, since I don't have as much experience with setting up the firmware of the 3D printer I figured I should ask for help.

I am using a VCore 3 500 with the old standard configuration at release including a V6 Hotend, Duet 3 Mini 5+ and Bondtech BMG.

My biggest problem are the waves in the print. They especially happen after corners and get better the longer it goes in a straight line. It also seems to overshoot the corners as seen in the logo.
On the inside there are some artifacts going upwards as well as seen in the pictures.

I assume the layer shift might be because of too much resistance or too much acceleration even though I felt like the printer should be capable of more than I have it set to right now.

Before the print I tightened up the belts some more to test out how it behaves since I had those overshoot issues in the corners before and thought that would make it better, so maybe that was too much?

I am grateful for any suggestions what could cause these problems so I know in which direction I should look.

Edit: Here are the settings from the config for speed and acceleration. The print in the pictures was done at roughly had of the speed.

M566 X900.00 Y900.00 Z6.00 E3600.00 ; set maximum instantaneous speed changes (mm/min)
M203 X9600.00 Y9600.00 Z600.00 E3600.00 ; set maximum speeds (mm/min)
M201 X1500.00 Y1500.00 Z200.00 E3600.00 ; set accelerations (mm/s^2)
