Why is this happening?

Doing a “large” project and noticing this on one side of the print.
(It actually looks worse in the photo than in real life.)

Anyone here know what might be causing this?
Filament: PETG-CF from Bambu (new out of the bag)
Nozzle: 0.4 (Right)
Profile: 0.20 mm Balanced Strength @BBL H2D
Default PETG-CF profile
Changes:

  • Wall loops: 10
  • Sparse Infill density: 20%

Is it printed in outer inner wall order?

No. Its inner / outer wall…

What I do not get is that it’s just in that area. below and above are okay.

Its like Pa went wacky in those areas. I see you have the h2d layer lines too. Sorry to hear this. Maybe a support ticket will help

I wonder if it would do the same thing with the left nozzle? :thinking:

It looks like the nozzle has hit your project.

You mentioned the filament was new out of the bag but not if you had dried it. The rest of the print looks good so it is possibly fine but also you could try drying it for 12 hours or so just in case.
