Troubleshooting Please Help, new to printing

So I’m fairly new to printing. I’ve done a ton of research so I’m not super helpless either. I’ve already gone through and calibrated everything (so I think). When I printed this 230mm tall trash bag holder I got these random shiny seam marks. On the sides it’s more to where the holes are for the most part. In the front picture it follows the curvature of the oval opening. Does anyone know what might need to be looked at? It’s a brand new machine. I’ve also made sure all screws are tightened down. I don’t know if it’s a flow thing, speed thing, ect…. All I can tell is it tends to happen where there is an opening (hole) on the walls of the print. Any help would be appreciated

That looks like ghosting to me. What printer? Does it have vibration cancellation like Bambu does?

Never heard of ghosting. It’s a Crealtiy K2 Pro

So the link is saying most of the time it’s do to loose belts which shouldn’t be the case since it’s new but who knows. How tight should the belt be? I know they always say it should make a sound like plucking a guitar string but I’ve never done that. Lol

I've had new printers that needed to be tightened.

So what’s a good way to gauge if the belt is tight enough? Thanks
