@mooklepticon I print almost exclusively with PETG and what I have found that works for me is to dry the filament, even if coming right out of the package. With some filaments, decreasing the nozzle temperature also helps.

@PriorityMotif You might have another (or an additional) thing to look at - there are little holes, which might be due to wet filament. This could also be the cause of the issue you are having - if the filament is too wet, it could cause partial blocking, which might create the thinning lines in the infill. This also would not be very visible in the perimeter.

If you hear pops during the print, then you have wet filament and, if that’s the case, I would suggest that you look into this first.

@Wfh Looks great! 👍

@s3rvant I’m hoping that this will help: https://forum.creality.com/...

@PriorityMotif Seems that the hot end is too far from the plate.
