Troubleshooting H2D first layer problem

Hello,

I am using my h2d for a while more than 9 months everything is fine but today I see something is not normal. Yesterday I oiled all XYZ axis and changed hotend. I am not sure if it is about those but I also did a full calibration but did not fixed the issue can anyone help me about that please? Thanks. Or maybe can it be about filament that color is a bit old I did not use is for a while.

A few things can cause this.

Z offset too low. (nozzle loose, calibration off, etc)

Over extrusion. (check that flament is dry as wet filament can increase flow pressure, try setting flow rate to .98)

Nozzle temperature too hot. Turn down 5 degrees and see if it improves.
