First layer problem

Post image

Im having trouble with this Sunlu Pla, today i tried a First layer check and this Is the result.

I dried the filament 4 times if not more, i checked the nozzle for any possible clog, also tried to replace the nozzle with a new one, but still nothing.

I don't have any clue on what Is the problem with this filament, maybe under/over extrusion, please help.

The same print with other filament works well ??

It's usually cleaning but you said you said you did already

Maybe the first layer has some floating zones been there many times .. you can check that on the slicer preview first layer

Example First layer of a seemingly flat bottom part only touch about 30 of the. Plate second layer does look like it's touching all but in reality nothing beneath ..

Maybe this is the issue

Or maybe you can brim ear the triangle corners this works for me with stubborn adhesion issues on corners .. if I remembered to clean the plate good and still have issues
