Hello everyone, unfortunately I have a problem with the print again. This time there are problems with the surface of the print. I haven’t had any problems like this before with the same settings.
It is printed at 120mm/s and the surface at 60mm/s and 100% infill.
I have already calibrated the print bed, flow and belt tension. I also printed the part with other filaments. However, always the same error in the same places.
Did you calibarte Flow and preassure advance with orca slicer?
Yes I did both of these. Before that it was fine and I didn’t change anything in the settings that could be due to the surface quality.
Hi Lukas,
The waves look like loose belts did you clean the carbon rods also ?
What type of filament is this ?
What is your flow & pa setting @ ?
What is your temp @ ?
Is you filament @1.75 if you check a few spots ?
I carried out the belt tensioning procedure after this problem, but it didn’t get any better afterwards.
The filament I use is SUNLU PLA+. I print it at 210 degrees (temperature tower already printed).
And the Flow is 1.04 and PA is at 0.028. The filament is 1.75mm.
The funny thing is that shortly before that I printed a part that still had a perfect surface.

Well if that is all ok and your nozzle we can see what this will do.
I don’t print with SUNLU PLA+ so I don’t know the perfect settings for it.
Reboot the printer to know fresh start and drop the flow to 0.9875 your pa is in range and set you volumetric speed to 16 you can run another pa test to see if you get the same settings.
How tall is this part 5mm ?
Can you print it with 20% infill for next test 5 top and 5 bottom & top surface speed @ 100 mm/s
If the side walls are shiny you are ok or flat black bump the nozzle up 5c in steps.
Keep us updated let see what happens 
Hello again 
The only problem was the flow. I calibrated this again with the Orca Slicer and reduced it to 0.95. Not only under the filament settings, but also separately for the surface under the quality settings. Now the surface is perfect.
Thank you once again for the help!
