BIQU Upgraded Direct Dual Gear H2 V2.0 Extruder 3D Printer Part Dual Drive Feed Extruder for Creality Ender & CR Series Printers, Anycubic Mega S, Geeetech Printers and Prusa I3 DIY Printer Kits

Perhaps I’m lucky but I’ve had no issues at all with this extruder , I have a Creality ender 6 Corexy I’ve not been happy with the results since I got it till now , I first cannibalised the printer and added a linear rail for the original extruder still not the best prints so added linear rails to the gantry print better but still not great so I looked at direct drive which I prefer (I also had the top cover for this printer which caused height issues ) I found this H2 Extruder on Amazon I ummmed and arrred for several days with the bad reviews , but wanting a direct extruder I decided to buy one , in the meantime I visited thingiverse for mounting bracket and print cooling fan , found both and printed then off on my ender5 , petg 100% fill 0.2 print thickness , as normal with Amazon dingdong the next morning it arrived , I didn’t realise quite how small it was but off I went to cannibalise the ender 6 a bit more , I was surprised how easy it was to fit , swapped the cables with the ones supplied fitted it to the linear rail I would say 40 mins see it fitted and all back together , then I had to change the steps yes there is no usb connection on the outside of this orinter you have to remover the bottom cover from the printer and connect the usb cable to the motherboard I have left mine conducted an run the cable out the side so connection to a laptop is no different to other printers , I did the e step calibration via prontaface I found the 932 Estep count was right so no changing I did run print temp test via prontaface just to update the board and to make sure the hotend behaved , i can’t remember the geodes fir it but search the net you should find the easy I started my first print a print I previously printed and with in the first inch of print layer lines had gone when I compared the 2 prints they were worlds apart to say they was printed in the same printer just changing the extruder I was surprised how bad stock hotends on 3d printers can be , as for the reviews I have to disagree with the negative reviews either they have a really bad extruder or just didn’t fit it or calibrate correctly I don’t know , grinding noise none what so ever, when I got the extruder I did open it up to see how grinding noise could come from this extruder but there’s a few cogs and wheels that I added a small amount of grease to just as a precaution , I’ve had 0 issues with it and I printed several large and small prints and it doesn’t complain , I had an issue finding the hot end silicone sock replacement so connected the seller seller who kindly set me some and I’ve since found them on Amazon so I’m very happy , it’s been on my printer now for about 2 months if things change I will update this review , for me it was worth taking the chance as I now have an ender 6 worth having , from this I have updated the extruder on my other printers from the stock crap supplied with the printer and print quality and improved big time , I recommend this h2 extruder on how it’s has performed for me

Fantastic package with proper heat and thermistor cartridge. Works well, plenty of heat power, pushes filament without any issues and is quiet. I thought there maybe problems with the small stepper motor but it works great. Small, light and cheap.

I have an anet A8 plus and sent through several different extruders before I tried this one.I couldn't get a perfect first layer print with any of them other than this one

Bought it with littlebit reservarions in my expetations, but to be honest, its top notch quality. Installed it for my Ender 3 Pro and it works without any hassle. Ofcourse you need to make backplate yourself, but there are plenty of solutions downloadable for free.Really nice would be, if Biqu supplied some part cooling solution too for this extruder.

Wszystko działa jak należy.

una maravilla lo simple y rapido que es, ademas hay multitud de acoples para diferentes maquinas que hay, lo unico te dioso es montar y desmontar porque hasta que le pillas el punto al montar tienes que presionar la palanca del filamento para que encaje bien

Der BIQU H2 ist genial, ich bin so froh das ich das originale Hotend meines Ender6 auf den kleinen Direktextruder umgebaut habe, hab den Umbau oft in diversen Foren gesehen und mich dann auch entschieden es zu machen, das war die beste Idee. Die Drucker Qualität ist viel besser, ich kann schneller drucken. Und habe seit dem Umbau keine Verstopfung mehr was für mich das beste daran ist .Und natürlich hat Amazon wie immer den besten Preis und wie immer super schnell geliefert .Absolute kauf Empfehlung.

Consegna Amazon impeccabile. Peccato per il pessimo controllo qualità del produttore: il motore non era assemblato e le viti "disperse" in mezzo agli ingranaggi, le tolleranze di costruzione rendono difficilissimo il riassemblaggio.... guardate qualche video su Youtube prima di acquistare.... Come rovinare un possibile ottimo prodotto!

Calidad precio no hay quien iguale esta printhead, super recomendada!
