PETG printed part has lines sticking out

Hi,

I’m printing with Elegoo Rapid PETG on the Bambu Lab H2D and i’m getting 3 lines sticking out of the print going all around the print. It looks like it’s just before and after going from long layer times to short, but one line is clearly in the short area and one in the long layer time area. Anyone have a clue what these lines can be? Using the generic PETG printer profile that I have had success with on other prints. Else i print on 0.2mm, inner/outer walls, 3 walls. Rest default.
