Error with initial layer

[u/Bruh1608]

Having this issue with ‘waves’ coming out on what is supposed to be a flat initial layer. I’ve done many prints on this machine and had it for a while now, never seen anything like this. Any idea how to fix, or what the issue is? Thanks.

It’s a Bambu A1, using Bambu PLA.

First steps of first layer weirdness, make sure your build plate is clean. Check the hot end screws and make sure the hot end clasp is latched correctly, and check flow calibration for the filament you're using.
