Sounds like you're having very typical consumer level 3d printer issues. 3D printing is not a science, it's an art. Every spool of every material from every manufacturer is going to be slightly different than the next which potentially requires adjustments to your settings. Different models will respond differently to those same settings. Some models are simply not printable using a FDM machine. There are a lot of factors involved in getting a good print and if any one of them is not right the printer won't work. This is the main reason why imo these things are just not ready for prime time in the consumer space. People have been groomed to expect their technology to just work but in this case, "it just works" doesn't really happen.

Things to look at/adjust in addition to the items posted above:
speeds and feeds
flatness of the build plate
nozzle temperature (and bed if it is heated, I'm not specifically familiar with that model)
ACTUAL diameter of the filament (not the nominal, you will need to measure it)
Nozzle to bed gap at Z=0 (should be just enough to slide a piece of copy paper between with a bit of drag)
