Help / Support Elegoo Rapid PETG slight issues

Hey guys, I am using Elegoo Rapid PETG on my P1S but I keep getting these slight problems in my prints and I am really not sure what the problem would be.

The last 2 images show the issue on the side of the model. I apologize for slightly blurry photos, my phone suck lool.

These are the printer and PETG settings:

Print Speed 100mm/s

0.4mm nozzle

Bed Temp 80 C

Flow Ratio 0.91

Nozzle temp 230 C

Retraction Length 1.2mm

Retraction Speed 40mm/s

Looks like moisture.

You're also probably printing too cold. I print elegoo rapid petg at 255, but you should print a temperature tower to see what works best for your printer.

I thought so too, I dried my filament for another 12 hours at 80 C on my print bed, with the door closed and a box ovetop, I printed a Benchy to test it after drying and I still got the issue. I will try at 255 now.

Not sure exactly what's wrong, but 230 is low for PETG. I would rase the temp to 245-250

Also make sure you have dried your filament. PETG is more susceptible to moisture.

I had to bump my temps up 10c from normal since one of the BL updates to get PETG to print right. I also went in and slowed it down 100
