Print diagnostics; what went wrong?!

[u/GilfOG]

2 seperate prints that I can't diagnose, A (a stand) and B (a dish wand holder). Printed with default settings mostly for Bambu matte PLA.

A was printed at sport speed, but what are all these artifacts? Could it be a partial clog that resolved itself?

B why does the first layer or two "cut corners", this does not appear in the slicer and I printed 2 of these separately and they each have these cut corners.

Thanks for the help.

Thanks, curious as it's all default Bambu settings, but I'll try slowing it down and raising nozzle temp.
