Problems with the surface - please help!

[hpoperator]

I am in despair and scream very loudly, but kindly, for help!

I have been studying Ellis page for about 5 days. Have Superslicer also set very well. The pages look great and my understanding has grown through the excellent work Elli has done. But unfortunately, despite extrusion_multiplier being set again, I can't get my surface set up well. Just to avoid misunderstandings: I strictly followed ellis instructions and did not stray from them here. In the places where he mentioned that you should, for example, define your own speed, the one at which you print in normal mode, I have done so (my printing speed is 75mm/sec, so moderate).

I first centered the flowtest at 0.92 and then finally I was able to find the final extrusion_multiplier at 0.925. Which I also entered as such.

Pressure_Advance I could find after the test also in 0.02:

Now after a subsequent print, the surface was mostly in order, but there are artifacts on it again in an irregular distance:

these "artifacts" or these small lines go against the direction of printing, virtually at the same point through several webs. I do not know what the reason for this is

I use a modified Ender 3v2 with Direct Extruder (Micro Swiss with Fullmetal Hotend), 2 linear rails on Y and one linear rail on X - both backlash free/smooth running and well lubricated (creep oil, not inhibiting), Z-belt drive, perforated magnet PEI plate, a Nevermore as filter, Fanduct= HeroMe 6 with 2x Radial 5015 component fans (= therefore also only 25% cooling during the pressure) and 1x 4020 as Hotendlüfter, a BL-Touch, motherboard is BTT SKR Pico, I run on a Raspberry Pi 3 Mainsail/Klipper. eSteps are set correctly, PID tuning completed and well leveled. Printing is exclusively ASA in an enclosure with 65°C constant pressure temperature (converted double-glazed beverage refrigerator). I print ASA, through determined SuperSlicer-TempTower, at 225°C at the nozzle and 110°C on the heating bed with standard very good adhesion.

The following are my SuperSlicer settings

My Print Settings:

My Filament Settings:

My Printer Settings:

My printer.cfg (/Klipper): - (In this are commented out comments, unfortunately in german language, sorry) https://pastebin.com/95B4Rp8q

I would be very grateful if someone could help me, unfortunately I find no way out alone :-(

Best regards!

Postscript: i reduced the perimeter_overlap to 25% (was previously set to 100%), then printed the same print again with the same settings and this is the result:

not disappeared, but better.

But what I also noticed afterwards, when I looked at the plates of the flowtest, is that these lines are also present in the 1.000 and the 0.990:

Maybe someone can get on here and help me find a solution?

I can hardly see the numbers of your pattern EM test. But looking at the picture of the undersite of your 0.925 EM calibration print, it seems that PA is not set well. The corners are very much rounded. I would advise getting PA set up correctly first as pretty much every subsequent calibration depends on a properly set up PA. Also what I noticed: Are you 100% sure that your filament has a consistent 1.75mm diameter? This case would be extremely rare. I would cut about 2m of filament, measuring every 10cm and average the values (i.e. with an excel table) to get a good estimation on the real diameter.

Hope that brings you a step forward :)
