help needed for the first layer calibration

Hi all,
My printer is having stringing problem (I hope I got the name right).
So far, i have tried: new filament and new nozzle. didn't help.

Can any expert help?
Thanks a ton

It would be easier to help if one could see a clear photograph .

Let me take a guess, You should drop the Z-Offset to lower this offset by another -0.1

those are big beads.
To get answers it hekps to give information.

As aminimum: printer type, print material, print settings: speed, layer thickness etc.

And - if known - build plate material.

It all makes a difference.
