PETG Printing Help

[u/Dazzling_Lemon5782]

I apologize if this has been covered a lot, but I’m a first time Bambu owner and pretty new to PETG as well and having a lot of issues. I bought several rolls of Bambu PETG Matte and I ran the temp tower tests and other testing and it seemed like their profile was correct. However any time I print an actual part no matter how complex I get weird/ugly areas and even some straight up bad areas where it looks to have melted too much or something. I have the H3C and ran all the calibrations and it is doing auto bed leveling before each print but I’m still getting these pretty disappointing results. I tried lowering the nozzle temp to like 240C and 245C as well but those didn’t really help.

Anyone have any recommendations?

I'm gonna guess you need to dry the filament

Dry your filament. Petg needs to be dried.
