Hello, i have a question: I printed a bigger part with Bambu PLA Silk Filament (Standard Setting) on my P1S and had following Problem (see picture).
Is this some kind of “ringing”? With which settings in Bambu Studio can I avoid that? The Surface on all sides of the model looks not clean.
I dried the filament before so the filament itself should be not the problem.
This was the Model with standard settings:
Thanks and best regards!
I would say it is not a smooth surface on the model.
The triangulation paired with a not 100% k-factor would be my best guess.
This pattern is not consistent with ringing. To test this theory, print a cube primitive using the same settings and compare the results. The cube’s right angles will make it easier to determine if ringing is present.
Additionally, please upload __your_ 3MF file as it was before you printed it. The image on your screen does not match the original 3MF from MakerWorld, which uses unoptimized default settings. Just because a file is on MakerWorld doesn’t mean the uploader knows what they’re doing. There are clear signs that this model was poorly configured for its size.
Based on the pattern in your uploaded image, I’d wager you’re using gyroid infill.
Finally, post a screenshot of the sliced model on your build plate and use the slider to show what the interior model looked like after slicing.
Here’s an example.
Thanks for the reply, I am going to try that after work to print a cube with the same settings and see how that goes.
I am currently printing a calibration Cube with the same silk filament. Lets see what the result looks like.
But I found that the poop looks a bit strange compared to my basic filament, see picture:
The grey one on the left is the Bambu Silk filament…
And another question, I saw a youtube video where someone said that this problem is common with core XY Printer and you have to adjust the belts. Does someone have experience with that? 
What do you think, this is my 4cm Calibration Cube with the same Silk Filament from Bambu. The Backside looks like it has ringing on it?
Another edit, I adjusted the Belts a bit on the backside of my P1S and tried another Calibration Cube with Silk and Basic PLA:
With the Basic PLA it looks better but the ringing on the Backside of the X Axis is still there a bit.
I also tried this small “ringing Test” i found on makerworld:
No ringing to see here.
Something else to watch out for are models turned into stl files with too low of resolution. I found the “refinement” setting in Fusion and was able to remove a lot of “faceting” in models by moving to “high” refinement. You can see the faceting in Studio if you look close. As an aside, “high” refinement still has facets but you can adjust the error slider even more to reduce error and make the facets so small you can’t see them at the cost of larger stl files.
This may not be what is going on and since it’s someone else’s model you are likely stuck with it. But for those building their own models, you can export near the same quality as step files.
I had time yesterday evening to tighten the belts and now they run in the middle of the pulley wheel on the backside of the printer. When you look for ringing on P1S online you find some suggestions about tightening the belts and center them on the pulley wheel…
I tried that and printed another cube, but I had the same results. After that I printed a “All in One 3D Printer test” with overhangs, bridges and stuff. On there is also a cube with 2x2x2cm but this worked without any problems.
My next step is to try out printing a cube with another layer of wall and reduce the speed a bit. I read ringing should also be present with high speeds. Maybe that is the problem with this cube?
