Hi everyone!
Anyone know whats going on here?
I printed 3 parts on the same plate and one of them had this issue.
Its like the upper layers has curled up or something.
Printed in ABS.
Any help is really appreciated, i have no idea what it could be
Welcome to the forum.
This issue is generally seen when the chamber temp is too low or the auxiliary fan is used, expecially with 3rd party ABS. The top layers are shrinking and the adhesion between layers let’s go. This issue isn’t normal when print in the X1C with Bambu ABS filament/profile.
What brand of filament are you using and what profile? What chamber temp are you seeing while printing? Are the auxiliary or chamber fan on?

Chamber temp is around 50 degrees Celsius i believe.
I have activate chamber temperature setting enabled and its set to 50 degrees Celsius.
Auxiliary fan is not on.
Abs brand is Clas Ohlson.
Im using the generic abs profile.
Could it be because the printer is positioned below a window and cold air could be leaking down?
I am in Norway and i cant remember having this problem earlier, its quite cold here now.
Yes this could be part of the issue. A chamber temp of roughly 50c is what you should look to maintain.
You might also try other brands of ABS as they are not all created equal.
What chamber heater are you using?
Sure it’s working properly? Use a separate temp sensor to verify.
Draft should always be avoided, especially with ABS.
Oh, and when the print is done always leave it to cool down to room temp before opening the door to bend the print off to avoid warping
