RE: Small blobs on edge of print, PETG
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.
