The ANYCUBIC Kobra 2 Hotend V5 J‑Head Print Head is an excellent upgrade for my Kobra 2 printer! Right out of the box, installation was straightforward and the adapter fit perfectly with the existing mount. The included 0.4 mm nozzle and ceramic heating cartridge heat up quickly and provide consistent, reliable extrusion with very few issues—even on long prints. I also appreciate the high‑quality silicone sock that helps maintain stable temperatures and keeps the heater block cleaner by preventing filament burns and drips. Since installing this hotend, I’ve noticed smoother layers, better filament flow, and reduced stringing on detailed prints. Whether printing PLA, PETG, or TPU, the performance has been excellent and very reliable. Overall, this hotend delivers great value, improved print quality, and dependable performance with my Kobra 2. Highly recommended for anyone looking to upgrade or replace their stock hotend!

I removed the old hotend per the instructions on Anycubic's website. The install for this was easy and it seemed to match the dimensions and look of the original with no visible differences, at first. Once I installed it, I did a PID calibration on the printer as recommended by the manufacturer and fired up my first test print of a temp tower. After the first initial layer, the nozzle immediately began to glob out filament and make a huge mess of the next couple of layers until I manually stopped the print. I took it apart and removed the hotend and cleaned a ton of filament that was jammed in the nozzle. I reinstalled the hotend but what I didn't notice at the time is that the PTFE guide tube that had pushed itself out of the neck about 2mm. When I went to reinstall it, I did just as the first time and pushed up until it was flush and locked the lever back in position. It seemed to have tension when pulling down so I put things back together and fired up a second print. Same thing, temp tower. This time, it laid down the first layer nearly perfectly so I walked out the room. As I was walking away, I heard a loud grinding noise so I ran back in to see what was going on. The gap in the PTFE tube caused the neck to not sit flush and it was not fully locked in position so it had dropped down after the first layer and been dragged along my $35 build plate and dug huge holes and trails in it. I stopped the print, heated up the print head and removed it again and as I pulled it out of the print head, this time the PTFE guide tube fell completely out of the hotend and onto the floor along with a small piece of filament that was left inside. Now not only am I out a functional hotend but I lost a $35 build plate. I try not to leave bad reviews unless I have to and the second install was a bit of user error as I should have noticed, at the point, that the PTFE guide tube was not properly glued into the unit like the factory ones are but it certainly shouldn't fall out.

Fantastic. Our prints have never been better and we’ve had the printer nearly a year. I can’t believe how much of a difference changing this piece has made. Will continue to use this. Not sure on durability just yet but hoping for hours of printing.

This nozzle is fantastic — it heats up insanely fast, so there’s almost zero waiting before a print. The tiny temp jumps are negligible. One warning though: do not get thermal paste in the nozzle opening or you’ll regret it. The instructions don’t explain this, but the paste goes only on the heatsink area where the heater cartridge makes contact (the white rectangular block with the wires). Easily one of the best upgrades I’ve made to my Kobra 3 V2. The steel nozzle tames picky filaments like glow, matte black, and other heavy blends with no drama. It’s my go‑to for anything abrasive or stubborn.

I say probably because I purchased because I got an error message " check hot end and wiring ". Replaced the hot end with this item and I still get the error. Most likely not the hot end but something else so I can't give the fault to this. It's " probably a good item "

Heats up the way it should an makes great prints no leaks an was easy to install

Worked great!! Fit perfect Solved my clogging issue instantly. I wasn’t able to print ANYTHING before this product. Heats up super fast and cut my prep time down by more than half. fast overnight delivery at a amazing price! So happy i can finally print

This item didn't exactly meet requirements as one was bent

Magnífico. No cuesta instalarlo de nuevo. Imprime muy bien. Al principio no podía calibrar y pensé que no valía (pensé en devolverlo), pero una vez hecho un par de pruebas de impresión primero, apagué la máquina y al día siguiente, intenté de calibrarla de nuevo con éxito. Lo volvería a comprar sin duda.

Was getting a print head error every time I tried printing. Installed this replacement and it now works perfectly. Perfect print quality and an easy fix.
