PETG outer wall defects
Recently swapped over from PLA to PETG. Getting lots of small gaps/bumps on external walls of prints. (pictures below)
Top and bottom layers both look good, no adhesion problems. Is it an extrusion issue? Relatively new to printing, just need to be pointed in the right direction 🙂
MK3s; Prusa slicer, standard settings; .200mm layer height; triple-checked live-z adjust using 75x75 square; PETG is Matterhackers Pro.

PETG is always produces little crumbs it seems. Moist filament can aggravate the problem. You might try drying your spool, although that's not what I usually see with moisture problems on PETG. Have you tried adjusting the z-seam position? Hard to tell for sure from the pics, but if set to random, you'll get a lot of little zits like that.

@bobstro
Was wondering if it might be moisture, but it's a new spool I opened only a few days ago. Will try both of your suggestions, thank you.
