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:
This is sad to hear. I have an Ender 3 Pro that has been nothing short of a workhouse for 6.5 years now. I've upgraded a few parts here and there as thats kinda the fun. Dual Z motors 2 yrs after, upgraded the hot end to a direct extrusion one a year or so after that so I could print TPU. Just Got the silent motherboard about a year ago. Solid as a rock. A friend got the CR-10 shortly after, same luck.
With all the issues and sketchy closed source madness Prusa and Bamboo are having, i was tempted to upgrade to a much larger Creality unit, but I guess I'll rethink or wait on that now.
Don't buy Creality. I really liked the K1 but their support is insanely user-hostile.
