Suggestion........

Clean and level bed.

Any of the free cad programs will let you draw a square 60 x 60 and just 0.2 thick (one layer thick)
Export this as an STL/step file etc, whatever you are happy with.

Print this, prefereably in several places and look at the result. Use a generic slicer setting for PLA or whatever filament you are using

If you can see daylight between each layer line your nozzle is too far from the bed, if any look like a rough sea the nozzle is too close. Adjustments can be made in the 'Z' offset setting in the slicer, use 0.01mm to 0.05mm plus or minus incremental adjustments until you are happy.

Loads of Youtube videos on getting a good first layer which will then give you good bed adhesion.
