I changed filament this morning, and all of a sudden, my prints are failing at the beginning.
I am super new to this and I am using a Neptune 4.

And tips?

hard to tell but i'd say level

#

clean your bed with rubbing alcohol and level it

recalibrating it

What kind of filament is it? Different materials have different adhesions, but as the guys above pointed out, this is most likely a bad first layer. So leveling and adjusting z offset should do the trick.
You can use following calibration file, or anything similar.

Also check some online materials on first layer calibration and leveling e.g.

it's also best practice to go through the calibration process for different rolls and kinds of filament

do a flow, temp, retraction test and you are usually good to go for future prints with that roll

Thanks for the help. I cleaned the bed, leveled it, tried adjusting my z offset. Now it looks like that.

I'm using standard PLA.

Doesn't look clean at all but i don't know what to do.

I would make the nozzle much closer to the bed

I'll try that out

#

It is much MUCH better.

#

Should I lower it a bit more or do you feel it will be good enough?

Lowered it a little more
