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:


My printer before this was an Ender 3 v2, I’m not useless. But when I can’t even find parts that fit, that’s a problem.
Yeah honestly I went back and read your OP and it sounds like maybe you straight up got a counterfeit unit or something? That’s wild. If genuine replacement parts don’t fit that’s super whack
It’s not counterfeit. Creality literally admitted the problem. It’s super whack, I agree.
Yea, none of what he says makes sense.
I have a K1 that doesn’t take early K1 parts. I think they changed things mid-production to use the unicorn nozzles that they evidently designed for another printer. During that time, the hotend was changed twice as well. This means if I order a hotend kit, I have a very low chance of actually getting the part I need. I’m not sure how to shop, because everything just says K1.
Usually that means a v1, v2, etc. there are k1v1, k1v2, k1c, k1 max, k1 plus, k1se, etc. so you need to verify exactly which version you have and order the parts specific to your system.
Creality wouldn’t explain that to me, and I’ve never seen a listing with versions for the K1. Can you find one so I can see what you mean?
I just googled it. You should be able to tell based on the hot end and serial number
But Creality can’t even tell. They asked for pictures.
Yeah you’re probably talking to some idiot that doesn’t actually work for creality their third party low level tech and either the Philippines or India so they have no clue what they’re talking about. Just Google it I I found descriptions on one site that said you can tell the difference between the V1 and the V2 based off of like the hot end or the fan or something like that that they’re only slight modifications. You may be able to go on crealities website itself and there may be a section to be able to put in for like your warranty and when you click into it it should give you additional details something like that is usually where I would start at.
