Problems with the corners of my prints

Bambu Lab A1 Series Troubleshooting

Hello everyone

I have been working for a few days with my A1 (my first 3dprinter) and I´m having some problems with the corners of my prints.

As you can see, some parts print correctly and others have some kind of lumps in the corners. They are both printed with the same parameters, same pla, etc. n fact, I printed three pieces, the one that is fine is the second one, while the first and third had the lumps in the corners.

Can someone help me with this?

Thanks for advance

The pressure advance is a filament calibration setting you will want to investigate: Bambu Studio>Calibrate>Flow Dynamics

Is the selected Device busy?

Mine is but the items are not grayed out, but I am running 1.9.7.52 still.
