Layer displacement but not. Bambu a1

Hi guys, already second time this week I have really weird issue with my prints. Some layers are displacing outwards around whole perimeter of the parts, like it It seems like layer shift but not. Geometry wise it looks like a chamfer, you could see that clearly on the photos. First thing what I have checked is how looks sliced model in order to understand if it comes from stl, but the model looks good. Have no idea what it could be.

Printed: lab a1
Bed: textured
Material: pla Bambu
Nozzle: standard 0.4



New print same results. Ghost chamfer is created. Not visible in Bambu Studio during slicing.

I am having similar issue, it always happens when the model has a base, and transitions to a wall. Like if you are prining a box/tray, the walls of the box always shifts out. It is very uniform and precise. and consistanly only happens at the base-to-wall transition.

I’ve been having a similar issue with my A1, it ruined a partial area of my build, but looking at some of the solutions sent they fixed the issue.
