I own an Ender 3, it's about 3 years old and the issues I have with extrusion, leaking and filament blockage are monstrous.
Examples of problems like this are filament flow issues, filament blockage, and filament leaking out of the sides.
Problems like this take all day to fix, and in the end, they are never really fixed. Everything is so overbearingly finicky.
Not only that, but it seems one of its parts breaks down about every week (this may just be due to its age but I thought I would note it.)
It seems I run into the exact same problems every single time I 3D print. Nothing ever seems to go right. I am getting really tired of it, and I'm wondering if these kinds of problems aren't so frequent/ as big of a deal with more expensive (better) 3D printers, or if this is just normal.
