BIQU H2 V2S Direct Drive Extruder 24V H2 V2.0 Upgrade for Ender-3 Pro Ender-5 CR10 BIQU B1 BX Voron V0 2.4 Dual Gear Extruder DIY 3D Printer Kit

EDIT: I'm updating my review to a 0 if I could. I've had nothing but issues with 2 of them. I've had to pull them apart more times than I can count and have cost my business thousands of dollars. I'll be seeking advice on getting refunds for these because they never should have been released the way they currently are AND without being able to buy accessories for it. They now FINALLY months later sell the 0.6mm nozzle replacement, but that's still not good enough. Released too early. DO NOT BUY IT IF YOU DON'T WANT TO PULL IT APART EVERY WEEKEND TO KEEP YOUR PRINTER GOING. Listen to the others who have had the same issue. I was recommended the H2 V2 by a friend who swore by how good it was. It had been a time since he'd bought his and we found there was a new LITE version. Now if anyone knows anything about direct drive it's that it adds weight to the gantry which we don't want, so grabbing a lighter model is an excellent choice. Fast forward to today where I open my package only to find that they supply ONE nozzle with the product and it's a 0.6mm brass nozzle. Disregarding other reviewers saying that it's awful, my needs require a 0.4mm nozzle. I started searching up the nozzle "M4 0.4mm Nozzle" indicated by the guide that it comes with and... nothing. Nothing comes up. Amazon, google, nothing. The M4 NOZZLE DOESN'T EXIST, yet. I've realised, like many others here that the nozzle isn't standard. It's 4mm wide, instead of 6mm wide like the volcano nozzles, and 1mm shorter than the volcano as well, this was done on purpose so even if you tried to bore out the thread to a 6mm sizing to use the volcano, you'd have a colder spot as you get to the end of the nozzle and would likely cause issues. I WOULD NOT recommend buying the V2 lite, yet. I contacted their support and havent heard back yet, however the company has said to others "Don't worry, we'll soon have accessories coming out for this". That's NOT GOOD ENOUGH. It was supplied with ONE nozzle and if something goes wrong with it or it's defective, you can't immediately use the product. Not to mention of someone wanted this to put a 0.8mm or 1.0mm nozzle in it to print big products, or for my purposes use a 0.4mm to print small or finely detailed parts, we can't even use the damned thing because it came with a nozzle size we weren't expected. Not to mention that ALL of the advertisement designs and photos don't mention the thread size ON PURPOSE as they KNOW it would deter people from buying their product meaning they already know what they were doing was wrong. I want to be able to buy more nozzles from anywhere, not only from BIQU where they can dictate whatever price point they want. A major let down. (A side note, from what I can tell the build quality is good however i'm not a huge fan of how the big rectangular piece is held on to the entire unit by a very thin bolt, seems like it'll snap one day, idk.)

This is the most put together system I have yet to try. With very little tinkering I was able to get this configured and printing at relatively high speeds and quality using the provided information and datasheets. I have around 500hrs of print time, and I have not had a clog, skipping, or wear. The filament path is pretty optimized and can print even 65 shore hardness tpu with ease. Speeds are good with a volumetric flow of around 15mm3/s The fan is seriously silent and I haven't had an issue with heat creep. The entire thing is metal and even after a few bed crashes it is still holding strong. The m3 holes allow a ton of mounting options for all the accessories you can want. There are a ton of mounting options on thingiverse and community designing almost any attachment. Overall a very reliable and easy to install design with plenty of community support and good speeds

i have now used this for around 3 months, and it works like a charm, and compared to all the problems the H2 V1 had, then i would say, this is how it should have been in the first place. The good: - Extrusion is always consistant, so my print have not had any artifacts on my prints, not even under extrusion. - The extruder has a lot of torque, compared to my old extruder ( a cnc aluminium mk8 type extruder). - the mounting holes all around the H2 extruder body, makes it very easy to install, or install parts on it, like i did. - the new placement of the screws holding the heatbreake in place is a welcome additon, even tho i havent had any reason to remove it. The bad: - The metal gears can be a bit noisy with fast retractions, but thats just how metal gears are by nature, when they are not submerched in oil like a gearbox. - You can not adjust the tension of the arm, i have yet not found this to be a problem, but this could be a problem for someone wanting to print in flexibles. Over all, for such a tiny direct extruder, thee Biqu H2 V2 is a great option, from what i have experienced so far.

Excellent little extruder, I have one on an Ender 6 and a X5SA, both Core XY and this thing is perfect, no complaints. This thing is small, light and compact and ideal for converting bowden to direct drive. Yes it clicks during retraction but its not noisy, people relatively new to 3d printing are too used to silent boards and quiet printers. It's a mechanical machine people, it's gonna make some noise.

bonne extrudeuses mais la plupart des vidéos de test sur yoube sont certainement sponsorisés par le fabricant car c'est pas non plus le top pour ma part réglage step a 962 et non 932
