Comment on Gaps in first layer, but not in brim?

Is it underextrusion/too high gaps or overextrusion mountains pushed up by the nozzle? It’s hard to tell if there is actual space between the plastic lines. Is this leading to print fails or bad first layer quality when the part is removed?
A tactic I’ve noticed by Orcaslicer, when using Bambu presets on my x1c, is to slightly overextrude the first layer. This forces the plastic solidly into a textured bed surface ensuring you get maximum hold. It doesn’t do this for the brim either.

Yea I’m beginning to wonder of flow rate isn’t adjusted for the brim. I may do a test as you can see through the gaps.

Well seeing as the brim is pretty smooth and properly filled I’m guessing it’s not a machine bed leveling thing.
Wondering if your print preset is messed up. Go to the Quality tab with advanced settings in orca, and near the bottom there should be “bottom surface flow ratio” as well as “elephants foot compensation” (i think, going completely from memory here) You may need to turn up the flow ratio and/or down the foot comp to get the bottom layer squeezed together properly, the defaults with the sv08 profile might not be right for your particular plate.
