I have an Ender 3 v2. I assembled it, and my first print just worked. Apparently this isn't very common. It wasn't difficult, but I can see places people would run into issues.

It was about a month later the problems started. Plastic extruder broke like they all do, and the extruder gear was done.

A bed leveling probe is a game changer. A PEI bed plate is great. Those tubing couplers are super fragile. Klipper is nice.

Now it just works and I expect it to for a long time.

The trouble is that people don't want to spend the time and effort to get there. Me? I like that any replacement part is going to be 20 bucks or less. Everything wears eventually.
