Small blobs on edge of print, PETG
Hi
I'm having problems with getting my PETG print to look all right. Can someone help me with what to do?
I get theese small blobs on the side of my print, i'm printing at 0.2mm at 245c.

Those look like seams. Try a different alignment in Slicer and see if they improve, or at least move. Several factors affect seams, K-factor being one, retraction settings being another. Try printing a few of the sample parts; if they don't show the problem, something you are doing when slicing is not helping.
The other possibility is moisture in the filament. PETG is hydroscopic - and sucks up water pretty fast. When that moisture hits the nozzle is vaporizes and causes a pop of steam that blasts filament out unexpectedly. So if moving seams to the rear doesn't have an effect, moisture is my second guess.
