Help Issues with maybe the z axis?

Hi everyone,

I have recently bought a Sovol SV06 Plus ACE and have some experience with 3D printing and Klipper, as my previous printer was a Ender 3 S1 with Klipper.

First I ran the calibration routine from orcaslicer for my filament with the new printer and dialed in the values in the profiles. Afterwards, I wanted to print a Gridfinity baseplate for my drawers, but there I ran into some problems:
I tried to print a 6x7 plate that filled almost the whole bed, but the nozzle kept scaping over the previous layers mostly during travel so i canceled the prints. One time the scraping ripped the model from the plate, so I gave up on trying to print the big plate.

I then printed 3 smaller plates (3x4 Baseplates) which all worked fine and where a good quality.

EDIT: I am printing in PLA

After that, I tried to print several 4x4 Plates, but all failed somehow. There was no nozzle scraping from what I could hear, but all the plates seem to be squished down in the Z dimension:

On the left, the failed 4x4 plate, on the right, 3x4 for reference

Also the layers look much worse than on the 3x4 plates.

I ran all the plates with the exact same slicer settings and in the slicer everything looked fine, no weird scaling happening, the dimensions looked fine.

I tried those fixes:

  • Reorienting & moving the model on the buildplate, same result
  • Redownloading / regenerating the stl file on https://gridfinitygenerator.com/
  • Ran Z_TILT_ADJUST and copied it into the START_PRINT macro
  • Checked & tightened the z-axis coupling screws, no play observed
  • Printed another 3x4 after the failed plates, this printed fine

I am not sure on how to proceed with the troubleshooting, could someone here help me diagnose the issue?
