Can anyone help before my printer is thrown out the window

remove filament from printer and wipe the nozzle when you level.
even the smallest amount of filament left at the tip of the nozzle will give you a false level.

You have to remember that we are dealing with layer sizes as thin as five 100ths of a millimetre. ANYTHING between the nozzle tip and the paper will make a difference.

Have you found the secret setting of 3D Printing the smaller more detailed models.

If No then Continue.

In my printing of PLA it likes to be printed between 192-202C with a Bed temp of 40-60C.
Depending on your 3D Printer the start speed can be a 30-50% as compared to the 100% set in the slicer as full speed.
After the first layer has printed you can increase the print speed. I can print from 72-86% near perfect Models quite easily though have printed faster with a few Print flaws.

I have in the forums uploaded my Cura's profiles they include Cura 15.04.6 - Cura 4. An have used other slicers thou continue using my trusty Cura slicers.

Again here are my Cura Profiles

I run 210 on my nozzel and 60 on my bed for hatchbox pla. You may have a bad slicer

If the filament is curling around your nozzle then it is a sign that your z-height is too high.

Throwing is definitely not a good idea dear, you can go for repairing.
