What is causing this pattern in the first layer? (lemmy.world)

Flashforge creator pro 2 with PLA, standard quality preset, textured removable magnetic bed on the build plate.

The first lines are straight, but as it makes more parallel lines to build the layer, it starts to develop a scalloped pattern. This creates issues with smoothness when it fills back to join it from the other side later. I've leveled the build plate, although I suspect it's not perfectly flat and maybe slightly higher in the middle. Is this my problem? It appears to have the pattern even away from the middle if that makes sense.

Result of lowering the bed - perfectly deposited at the middle, underextruded at the edges

Manually adjusting the bed or just tweaking z offset? If you’re not using offset I could try that in small increments. It looks like you’re really close tho.

It could be a slicer thing. Gap infill settings should be looked at.

Also calibrating pa and flow might help. You need to calibrate these for every filament ideally.

That's not very underextruded on the edges, and doesn't seem indicative of bed warping IMO.

Which slicer are you using? If you're using PrusaSlicer the setting you're looking for is under Advanced > Extrusion Width > External Perimeter

Other slicers will also have this option just might be called something else.

Bump that up by .02mm or so and you'll probably be golden.

For reference on a 0.4mm nozzle my external extrusion width is 0.45 for external perimeters.

You might also need to bump up the infill/perimeters overlap coefficient by a few percent.
