Creality Original Extruder Assembled MK8 Hotend Kit Full Set Upgrade with Low Friction Capricorn Tubing for 3D Printer CR-7 CR-8 CR-10S S4 S5

My original hot end thermistor failed and the thing went into a meltdown. This new unit was super fast and easy to attach and was printing again great in minutes.

My original print head burnt up on me and I needed a replacement. I went through several different vendors trying to get it fixed and found this one. Installed it and it has been working like a champ, even better then the original from Creality. Since then I've updated the cooling system on my printer but the hot end is still from this purchase. If you are having issues with your print head I recommend you get this one. For the money it is a really good product and so far I've had little to any problems getting this to Print PLA and PLA+, may now even get brave and try another filament.

The new hot end took all of two minutes to install and worked perfectly upon its first test heat-up. My only complaint is that it did not come with mounting screws. Most people more than likely will already have them but I swapped back to this hot end after using an E3D V6 set up that did not need the old screws. I more than likely threw them out which or course is my own fault. The product comes as described, the extra screws were just wishful thinking. Fortunately I had some spares laying around. Anyway, the product works fine and takes only minutes to install. I would absolutely recommend that Creality printer owners purchase it if they need a replacement.

My Cr10 was aging after a few years of constant use. My horned fans were dying so I soldered in new ones. Then my heater cartridge went out in the hot end so I bought this replacement setup. I wish I would’ve just done that to begin with. Installed right in, no issues, have put about 100hours on it so far with no issues at all. Highly recommend!

I got this assembly because I didn't want to mess with the electrical to replace the hot end and the fans. I was hoping it would just be plug and play. For the most part it is, but they don't include the small pneumatic connector (pc4-m6) for the extruder. So I had to pull the old bowden tube out. It worked for one print, which came out great, but on the second print and the next two after that, the connector wouldn't hold the new Capricorn bowden tubing, it kept pushing it out. So I'm guessing that I need to replace that part, as I already trimmed the tubing flat with a Capricorn cutter, and reinserted it multiple times as well as replaced the little clip. It would have been helpful if a new one had been included with the set.

The extruder assembly works well except on arrival the heat block was loose and filament oozed all over the place. After cleaning the heat block thuroughly and screwing it back together so it wasn't loose/didn't leak it ran fine for maybe 40 hours of printing and then a long print failed because the heat block seemed to loosen itself and plastic began oozing out the top again. I'm ordering a new hotend just because I don't want to deal with the recurring leaking which i've never had issues with on any other hot ends. Assembly was quite easy though.

So far so good. double check everything is tight and together before you actually start printing as I have bought similar hot ends in the past and they came loose and had issues with leaking. I have multiple printers but the one that's was going on was the HICTOP cr10 knockoff and I found that the wiring harness was pinned differently on the assembly than as the original one for my knock-off printer. I would assume that this is due to it being a knock off and it not being an actual creality. I ended up having to unsolder the connector and resolder the wires back on in the correct order for my printer.

I started having issues with my print head showing squeeze out where it shouldn't. It was looking like a mess so I went the easy route and bought this. Plug it in, 2 minutes, level the bed and kicked off a print it's been going flawlessly for the last 6 hours. I bought 2 and plan to always keep at least 1 of these on hand for backup.
