OK, I would suggest a few things. Why are you printing on a Raft? this is not normally needed especially for your item.
Also it is very difficult to make a good quality print at 0.02mm layer height. Trust me I know. You would be better to print with 0.06mm layer height and it will come out looking better then you first picture.
You have spiralize the outer contour turned on. Turn this off.
Also 15mm/s print speed is very slow. Not sure what material you are using because you still didn't mention but it can easily over heat at that speed and such low layer height. You can reduce the temp really low but this will cause to much curling of the edges. I would suggest 30mm/s print speed
still it says 12 hours and the first try only took 1 hour
i changed somthing on mistake and now all is worng:\
Maybe you originally had the layer height at 0.2mm not 0.02mm?
Also like I said, 15mm/s print speed is very slow. This could be 30mm/s or 50mm/s
Also. Are you actually using a 0.25mm nozzle?
@daniho deleted the other topic to keep it here. Also please don't duplicate post if possible. Thanks!
Can you share more info?
What software and version are you using?
What print settings?
It looks like you have concentric infill turned on maybe but not sure with the limited amount of information you have provided.
