K2 Plus - Visible Layer Lines

Hello everyone!

I’m encountering my first major issue with my K2 Plus. So far, I’ve had no problems printing PLA, but PETG has been a different story.

This is my first large model on the K2 Plus, and I’ve noticed a pattern of visible lines forming:

  • They start appearing after the first third of the print
  • They become very pronounced toward the middle
  • Toward the end of the print, they start to spread out

I used Creality Slicer V6.0.4.1797 and the latest firmware (1.1.2.10). I previously printed this same model on a Sovol printer, and the lines were not present.

Has anyone encountered something similar? Any suggestions on what settings or hardware adjustments might help?

Thanks in advance for your insights!

You can try to
Heat the bed 10/20min before print.
Try a z-offset ( +0,025/+0,035)in fluidd just before the print start with the first purge line (i use that for petg)
Dry your petg. ( The little points probably disappear)
