This happens with just this filament, dried it, set retraction to 5, nothing. i have no clue why this is happening. IMG_0488.MOV - Google Drive Hardened steel 0.4 nozzle. A1 full size. using external holder. Any tips or info I should give?

PETG likes to string. If you know for certain your filament is really good and dry (like, really good and dry), the next thing to check is temperature. You may be extruding too hot. You could just take the empirical approach and lower extruder temp by 10º to see what happens, or you can print a “temp tower” that will help you pick the optimal temperature in a more quantitative way.

I realize now that your second answer might be correct. I’m printing it at 270 because the extruder was skipping and I thought that my nozzle was too cool, not melting the filament at 255, and clicking. Now I realize that it was because the filament hadn’t made it to the nozzle, and I just had to give it a little push. What temperature should I set it to?
I typically print PETG at 250. But if there are a lot of unsupported overhangs, I might drop it to 240. There’s a “temperature tower” calibration model you can print that will do incremental temperature increases so you can see what temperature prints the best with that particular filament.
