I have a Flsun Cube printer with an updated motherboard from MKS. I am using PETG filament. Everything I print has the pattern that the attached image has. It tends to only occur on the down side.
Printing with PLA does not do this. I have tried heated extruder @ 250, 240, 260 along with 5 degree changes. The bed temps have been tried between 50 and 80 degrees. What is causing this, or is it a sign of using PETG? The prints that are done in PETG are far nicer than PLA output

Could you be more specific what pattern you are referring to here? I see the 'pattern' that is caused by the extrusions here. The 5 perimeters with little bits of solid fill. Is that what you are referencing?
