Struggling with first layer adhesion/quality issue

Hello,

I’ve been using the Smooth plate for some prints, but I keep having issues with the first layer quality. All prints were printed using either Bambu PLA Basic or Matte, with Auto Flow Dynamics enabled.

As you can see from the photo below, some areas are performing way worse than others:


(Note that this was taken prior to fully cleaning the bed using warm water and dish soap.)

After washing the plate, the results were clearly better but I still wasn’t getting a smooth surface:

However, here comes the puzzling part: when I do a full bed first layer test, it comes out flawless! There are zero spots with artifacts and defects, it’s printed perfectly.

I might still redo the bed calibration procedure, but I’m really puzzled by these results. Are the other first layers issues caused because they have smaller surface areas? I really love the look of the smooth plate, but it’s starting to get a bit annoying when I keep getting these issues.

If given the errors I see, I’d probably run a volumetric flow rate wall test to see if it’s behaving as expected vs the filament profile. While that’s usually an Orcastudio thing, I think there were a few manually created ones using modifiers on makerworld and printables. They’re for x1c size and speeds, but I don’t think we’re that far off to be unable to use it.

It looks like “Auto Flow Dynamics” is disabled for the full bed first layer test?

Also, you could try to ensure auto bed levelling is enforced and not just in auto mode

It was set to “On”.

This option was also set to “On”.

Were you able to resolve this issue? I have the H2S and have this same issue. I have done all of the calibrations, adjusted the z offset, washed the plate etc. any updates?

Loosen/remove the front bed screw and re-try
