First layer issues

Flow of different brand filaments or even different colors within the same brand can be different. you might need to increase or decrease temp.
are the perimeter lines nice and smushed or are they like cylinders just barely squished into the plate?

 

What are you currently using to hold down the part anything. What if any is the bed temp and what temp are you extruding at? Can you upload an image so we can see what you are talking about.

There are quite a few reasons for filament not sticking so the more information given the better.

 

Glad to hear it now you need to start posting some pics LOL

 

Without seeing anything at all I would GUESS that if you have first few layer issues it is a z height adjustment.

The first few layers are always the worst because of the inconsistencies that exist when these layers are put down if the first layer is too low then the second layer tends not to be embedded when it is put down to that it never really gets stuck to the first layer. If it is too high then the layers tend not to stick at all because the first layer is not really stick to anything and thus just gets moved out of the way when the next layer comes down on it.

What you want is the very first layer to be slight flattened against the bed that way it sticks and the printer settings about layer height are set to push the next layer down into the first layer somewhat so it actually bonds into it.

The first few layers go through a lot of tweaking as they get laid down but eventually things even out for the most part and subsequent layers seem to do just fine and that is what a lot of people see..The first few layers not so hot but then it start looking better. The problem is people thing it is like driving a car with the engine not warmed up a bit and that as it warms up it runs better so everything is kind of all right but this is not the case with 3d printing when you print you should be able to print great right from the start if all the settings are set correctly.

I use this next pic a lot because it shows some good things in it
First: The skirt nicely flattened and completely opaque so it is not too thin tells me the z height is on the mark
Second: It also shows the consistency in the layer around the entire print so that tells me at least the part of the bed where this print is being laid done is nice and level to the nozzle tip
Third: the single raised line in the upper area is where I was playing with the z axis manually and you can see what the full height of the filament would be if it was just sitting on the bed and not flattened, the difference between the other lines shows how flattened the good lines actually are.

So even though I stopped this print I could have let it go and it would have probably been just fine as the single line would have been compensated for by other layers.


I wish you continued good luck and hope this helps in some way

 

That is actually the best place to do it since the first layers and the perimeters are going to have almost identical conditions you can verify what the first layer looks like and if it is bad stop it right there with wasting so much filament and time.
