Try slowing down the print speed on the first few layers to something like 10-15mm/s. You may also need to raise your bed temperature if you haven't already. The stock 40C temp setting is too low. Most people run 60-65C

Try making your first layer .2 or .3mm...you may have to go in and toggle a check box in Cura to see the first layer thickness option. You could also try using a raft as well, but they are not always ideal. The nozzle temp varies by spool...technically you should print a temperature tower for each new spool, but if you are not adhering from the start, that isn't going to do you much good anyway unless you slice it at .3mm or something like that.

There are a ton of factors that go into what the temperature needs to be. A lower ambient room temperature can cause you to have to run it a bit hotter. My basement is usually pretty cool, so I have to run things on the warmer side. Also beware of humidity...you should take measures to keep your filament dry and not allow it to wick moisture into it. If you are using the spool of filament that came with the printer, set it aside and use something else. The demo material is very hit and miss on quality. I have great results with Amazon Basics/Overture PLA...but right now you have to take what you can get.

No 3d Printer is going to be flawless, especially not a $200 one. You are going to have to learn the ins and outs of how to design and run the printer successfully. The general public thinks you just click your fingers and a finished part comes out of the EZ bake oven, but that couldn't be further from the truth.

I highly recommend joining the Ender 3 Facebook group and sucking as much info up as you can, and ask questions. The folks are helpful and all have gone through the same learning curve as you are undertaking. Once you have some experience, the machine you bought has great bang for the buck.

A lot of people use glue sticks also if you don't have hair spray laying around to try.
