Nah its easy to fix if there are any problems!
Yeah. Was just looking at the Eclipson planes. They look great!
That's what I had. It was a great printer. I sold it to a buddy because I didn't use it enough. The first upgrades you need to do is stiffer bed springs, aluminum extruder, and Capricorn bowden tubing. I also printed a fan cover for the motherboard and drag chains for the cables from the hotend. I also did printed belt tensioners. Keep your bed clean and level and use hairspray for adhesion. The Ender 3 also has one of the biggest user bases out there so you can fix about any problem on them by consulting Google.
I'd recommend using fusion 360 it's an amazing program and it's very popular. Fusion 360 can convert cad files to stl no problem. It also has its own built in slicer, but I don't use it. For slicing your models, cura is a good slicing software.
