It might be because your man ctrlpew has a getting started video where he goes thru initial Cura startup and setup and really helps familiarize us with the interface.

I've tried to install and navigate a few other interfaces, but Cura still feels easiest. I've printed the same models with eSun on the recommended basic pew settings and had nothing but success. I've also spent days tossing warped or failed prints, tweaking heat and cooling, and then trying to print again. I've tried a few other brands like Overture, because they came in a cool color or were a little cheaper. Just use eSun or Novamaker PLA+ unless you are printing a specialized/experimental model that the designer recommends. Just do an Ender 3 Pro, which is linked at the bottom. There are a few things I've learned from various sources along the way, or thru failed experiments, that I wish someone had compiled into one location: These packages have everything you need from multiple manufacturers collected into one package to get you from print bed to pew time without scouring the internet to shop for rails and blocks. Down below you'll find buttons to take you to a site you can download these STL files from, as well as links to new Complete Parts Packs. The G19 and G17 FMDA models are the most popular and proven printables, so they are an excellent start.

We're doing our best to collect some resources to help those just getting started with pew printing on this page.
