Strange first layer

[lui2004]

Since few days i have this strange first layer

i dont have change nothing

i print pla with nozzle: 200°C, bed: 60°C

if you need some other files for check

it's look like you have some fat on your print bed try to clean it with acetone and sandpaper or equal

[lui2004]

I have clean it All and with sandpaper

My and first layer looks like this in pics

I dont know what it is

@lui2004 Over extrusion. Either too much flow, or too close to the bed.

@lui2004 maybe also old/wet filament? Do you hear any popping as it extrudes? PLA isn't as bad as nylon/petg, but can still absorb water over time. I've also found damp filaments swell a but so you get some overextrusion at the same time...

[lui2004]

Thats only the first layer the rest of print looks perfect.

Flow and extruder is calibrated

[Phaedrux]

Then likely too close to the bed on the first layer.

As phaedrux says you're to close to the bed move your nozzle some babysteps higher
