Hey,
I am using Orca Slicer as my standard slicing program for my P1S.
Today I wanted to print a model which I designed myself and I already printed in the past - last one was yesterday.
I did never save it inside the slicer so I always create a new project and import the stl file to the slicer. At today’s attempt I noticed weird lines at the top surface while checking the print in the preview window. The second weird thing is that the slice yesterday was perfectly fine without any weird lines. The Model itself hasn’t changed either. The print failed but that’s a different story 
Here is a screenshot of the slicer:
What I already tried:
- changed Filament from PETG to PLA
- Used a generic profile instead of my own
- restarted Orca Slicer
- restarted my computer
- imported same stl into Bambu Studio (the problem does not occur there)
- exported the object in different types of files (.obj, .3mf, .stl)
- compared settings to settings in Bambu Studio - all settings seem to be identical
Any ideas?
Thanks in advance.
