BIQU H2 Extruder V2.0 New Upgraded Dual Gear Extruder 3D Printer Dual Drive Feed Not Stuck for Creality Ender&CR Series Printers, Geeetech, Anycubic Mega S Printers and Prusa I3 DIY 3D Printer Kits

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

un calvaire a mettre en œuvre! et le filament fond dans l'extrudeur.
