Hey folks,
I was printing a frame with a fresh unopened roll of PETG. I haven’t seen this type of thing before. I’m guessing it’s because I tried a new (to me) cura setting to move the seam to the corner.
Besides this area, everything came out great.
Any tips on how to get PETG and corner seams to not do this? (Or is the issue unrelated?)


I generally calibrate per filament brand and type. Sometimes different colours of the same brand/type behave differently, but usually it’s fine. Haven’t really had issues where I had to change settings between batches.
Make sure you do the calibration on filament you’re sure is dry however… Then, in case you run into issues later just make sure it’s dry first.
I can’t believe how many of my print issues were simply related to wet filament.
