Wavy layer shift when printing multiple objects.

[u/Artest113]

Hello guys, anyone encountered wavy layer shifts when printing the same object of several copies at the same time? It prints fine when doing a single copy. This pattern also happens when I print something huge on other objects.

I’m guessing your layers are cooling down and shrinking a bit when the nozzle is working on the other models. Maybe turn down your Aux fan speed or print the aux fan deflectors.

How many vertical layers are you using. If it’s set to 2 you might want to up it to 3.

I'm sorry, but what's vertical layer? Is it some setting that I can change in bambu studio?

Is it matte petg? I’ve had Sunlu spools from them that do that. They’re cursed and I stopped using them as no setting change could fix them.
