I've been struggling with my K1 since Christmas. I bought it on sale for Black Friday and no matter who I contact at Creality, no one can tell me what replacement parts to order. K1 parts don't fit my printer. They want pictures to see what 'buckle' I have, because my serial number isn't enough information, but who wants to tear down a printer just to take pictures? Now my thermistor is broken (a leg weld just fell right off while I was fixing a clog), and I can't order a new one because what do I order? This printer doesn't take K1 parts. Every time I order something, it has to get shipped back. I'm annoyed and venting, but also trying to help anyone else considering a Creality printer. Don't do it. Their support is a joke and they take zero accountability.
I've added an image for help explaining the problem. These two JST connections are completely different, but both are supposed to be for the K1. And both of these listings are Creality Official:
Yeah, I'm not even sure what to get now. But they're taking this Frankenstein monstrosity back or I'm going to burn them to the ground. I'm loud, angry, and litigious.
Prusas are expensive but they fucking work.
It's between that and an Elegoo.
I have no hands on experience with Elegoo's printers, I have a pair of Arduino Uno clones with their brand on it though, and they aren't bad.
