ANYCUBIC Kobra 3D Printer Extruder Hotend V5 J-Head Print Head with Silicone Sock 0.4mm Nozzle 24V Ceramic Cartridge Heater ONLY Suit for Kobra,NOT Work with Kobra GO,Kobra Neo, Kobra Max,Kobra Plus

I've had no problems with it, works great.

After having been thrilled with the performance of my Kobra 2, I noticed the print quality begin to decline.Long story short, I mistakenly got this in hopes of modifying it to take regular volcano nozzles, and after realizing some goofs I had made, I decided to just install this piece.What a difference!Yeah. I could have gotten away with just cleaning the original one, but I had managed to bake some filament in there pretty well.Anyway ... Get one of these, or clean up they one you have. Slapping a new one in there was quick, easy, and painless.

Anycubic Kobra user here, had a simple issue that ground my PEI build plate and subsequently caused my hotend to get clogged with burned PLA. Before this incident, I printed PLA, PLA+ and Silk PLA perfectly with no issues, just slice and print. After this clogging incident, Instead of cleaning it out, I decided to get a this new hotend with my new genuine Anycubic PEI build plate from Amazon. (Anycubic is currently out of stock of Kobra hotends and I couldn't find another source of authentic Kobra hotends) Little did I realize the nightmare that it would put me through over the next week. I tried every calibration known to man including multiple attempts at PID tuning using pronterface. Nothing but stringing, blobs, and horrible layers due to unstable temps. PID tuning actually made things worse by then introducing abnormal hotend temp errors. After a week, I gave up and decided to splurge on a Bambu X1C. But today I decided to give the Kobra and the old clogged hotend one more chance by cleaning it with a heat gun. Once I got the original hotend completely cleaned, put a new nozzle and PTFE tube in and reinstalled, then re-tuned PID, I was back to perfect prints! That proved to me that this generic hotend is complete junk and will be returned back to Amazon.

Perfect fit for my anycubic vyper. Works great, I have bought these several times.

Had to replace a broken hot end in one of my Vypers. This one has been good enough, works at least as well as the one from Anycubic. The only issue I really had was that it surprisingly did not come with even one sock. So if you need socks, order them separately I guess.

I have found it just as easy to buy the whole hotend and swap out the old one after a major clog because its just 2 machine screws and 3 wires it takes less time than doing a nozzle change and cleaning of the heating block and with this u get a new teflon tube and new thermistor and everything it prints so nice after a hotend swap out if it majorly clogs again im gonna just get this hotend and make it like brand new so easy. I love it.

The hot end on the FLSUN Q5 is cheaply made. It looks nice but after a few dozen prints it will fail. I replaced it with the UniTak 3D V5 . It's not an exact replacement. I had to mill off A LITTLE of the opposite sides of the heat sink fins to get it to fit between the two fans. It could have been done with a jewelers saw or even carefully with a hacksaw, possibly even filed away but I had access to a mill of sorts so I did it that way. Also two tiny holes need to be drilled into the bottom fin. Make sure the flat sides you just cut are aligned properly between the fans before you mark the holes or just have a couple of extra holes. Don't cut off too much fin as they must cover those tiny mounting holes.

works great put it in and my printer is working like new again.
