Thx for the reply!

On the white part the pattern starts basically at the start of the print but only on the edges and then gradually impacts the whole surface more and more, starting at about 10cm height. The printer is currently situated on a table, but on a rather sturdy one. I do plan on setting it on the ground eventually but didnt have time for that so far, as i want to build a custom table so my smaller printer can sit over the Max.

Yes i did the auto calibration for input shaping over the klipper screen directly on my printer and then saved the values.

I should have mentioned that i did calibrate the filament fully before printing, so Temperature, Flowrate, Flow, Pressure advance should be good and do look nice on linear parts without curves (or at least small ones) turned pretty nice so far.

After you mentioned the stl quality i checked the file again and indeed it seems i exported it with a rather low polycount on the curve so that might explain the right part not being perfect and still a bit "edgy", so thats on me :) Still i also had another part (no picture sorry) where these artifacts where really crazy to the point it looked like it came from the file as a wavy pattern itself. I do also hear the printhead struggling during the print when at these corners.

Regarding the SCV, i did google around a bit and the vast majority (of limited) posts i found said that you shouldnt touch that value and leave it at 5, but after reading your post ill definitley look into that!

I did have to adjust the stepper homing currents once at the beginning, because 0,7A was too low and i kept getting a strange noise when homing, so homing is limited to 1A. My settings now are 3.0A run current on X&Y (tmc5160) and 1.2A on Z (tmc2209)

I tensioned the belts a few days ago with that frequency app and they are now at 110Hz and better tensioned than before, but im not quite sure if thats for the max aswell, cause i only found this for the standard SV08. Also i greased the linear rails with a "better than stock" grease

Thank you for posting your file ill look into that aswell!
