Looking for help. I’ve recently got a X2D and it’s quite a downgrade in comparison to my P2S. I’m printing using the default 0.24 profile and Bambu labs’ own PLA Matte profile. And it just gives me terrible top layers. I’ve tried: Running the printer calibration. Drying the filament in the A…

Your top layer issues are 100% happening because of 5% infill and insufficient top layers. Go through your print preview layer by layer, on the first solid layer after the infill you’ll see that it doesn’t go all the way to the outer walls.

I’m also having X2D print quality issues, terrible top surfaces that were perfectly fine on my P1S I owned prior. I’ve printed the same model as OP but with 15% infill and also gotten a terrible result

Seems like you did not searched too much around but there are more than 10 reports now for similar problems. Maybe even more. I am also fighting with same issue either under extrusion on top or bottom or over extrusion on the edges. Recently able to fix the under extrusion on the bottom. But have n…

Have you ever seen the ripples in sand in sand dunes? They are created by wind blowing across the sand. They look very similar to the waves on the top left surface of the first picture. The rough look on the right side looks very similar to what happens when there is slight lifting on the first l…

What 3dEd said above makes a lot of sense, but also I will add that Bambu matte seems to be big trouble maker for x2d and his default profiles. You can try to use the 45 degree deflectors. And also I have very good results in the last days to calibrate the process + filament profile by just printin…

I have been in talks with Support, and have not had success yet. They’ve since recommended: Retramming/Manual Bed Leveling. Full Filament Calibration. And last thing they send me was spare parts for Extruder Gear and Servo Motor. Unfortunately, it’s showing the exact same result. :frowning: So …

I think I’ve fixed the issue, I am currently running this by Bambu support, but in the meantime, here’s what I did to get much better results. TL;DR Flow Dynamics to 0.04 and Flow Rate to 0.966, and Max Volumetric down to 15. I’ve calibrated it using Calibration Guide - OrcaSlicer Wiki with Max Vo…

Very good experience! FYI my auto calibration for pa/flow dynamics show also between 15-18 with different filaments. Manual with bambu studio usually around 18-22. From my manual test I can see much higher pressure advance. Also I got better results by dropping flow rate around 15mm3/s for the mat…

Now spend some time with trying to calibrate the matte on the AUX and this seems to be a bigger challenge compared to the main. You know, for PLA multicolor prints. And the strange thing is that actual objects are not coming really bad or even they could be really good. But simple cube seems to be l…
