New Ender 5 max - what i am doing wrong?

Ender-5 Max Printer
1

After using a 3 v3 KE for years without any mods / special settings, i bought a 5 Max. From Start, quality of prints was not very good, and became worse. Can someone with more experience have a look on my pictures, to give me Advice what to change? When i bought the V3, i had issues too, and was getting help by People that knew with one view what was going wrong. I aborted printing after first layers. The Object is a part of an enclosure and should start with a plain plate with some text.

I used PETG at 240/80 degrees.

Did you calibrate the filament profile? This looks like at least in part a flow rate issue. I don’t have much experience with petg so don’t know if those temps are good or not, but the E5Max does have a brass nozzle which conducts heat differently than a hardened steel you might be used to. You might find lowering the temp for the brass nozzle a bit will help too.
