Hi! Looking for some advice here from friendly local experts.

I’ve printed this with Elegoo Neptune 3 Pro, 0.4 nozzle, Elegoo PETG filament, no enclosure. Using PrusaSlicer.

This print is basically all walls - the hex grid is thin. It’s 2mm thick and each segment is 1.5mm wide. I set 3 layers for walls in slicer. It was printed vertically, just as seen on picture.

The solid part of the print (back wall) came out just fine, but the hex grid part came… dirty. On the picture, there are a few hex segments that just broke off during the print at the base of vertical segments. And the rest of them have small loops of filament that stick outside of the intended surface, to the sides.

My suspicion is the print temperature is too low. I’m printing at 230, which is the low end of 230-260 range of the filament. But in my previous tests I noticed stringing that starts around 240, so I did a few other prints that were just fine at 230, and I made it my default temp for this spool.

Or is it just too fine detail for my printer with PETG? Or something else that I am missing?

    Thanks! I’m a beginner, got the printer about two months back. I didn’t do any special tuning apart from auto leveling the bed.

    I printed a temp tower with this filament, and it was okay from my viewpoint. Long overhangs were droopy on lower temperatures, and it had stringing from pointy ends on higher temps. I printed a few PETG prints before, but nothing with such fine details as this hexagonal thing.

    Can you point me to some good source of info about tuning? For a noob like me it is hard to tell good resource from slop-compiled one…
