I purchased this as I had damaged the original x gantry when re-installing some components. It was cheaper than an original gantry and is extremely sturdy. It was also extremely easy to fit and includes the advantage of making the extruder direct drive making the machine as a whole more functional.

Decent clone, easy to install, makes a good budget friendly upgrade and can still use your current extruder that fits nicely on top.

I've been pretty much avoiding going the Direct Drive route because I always felt I had my Bowden + Linear Advance setup pretty much dialled-in. But I'm a tinkerer at heart, and I needed a weekend project. So I grabbed this Direct Drive bracket and went to work. First things first, I parked it on a Voxelab Aquila - an Ender 3 V2 clone. In fact, that's why I chose this bracket: turns out, the pictures shows the bracket installed on a rig with an Aquila shroud. So I knew it would fit. And it did. (FWIW, I'm also rocking a BMG clone - you know the one: all plastic - so I knew my extrusion was already in good hands right at the start of the filament path.) So, 30 minutes after receiving the package I had it installed. I inverted my spool holder so the handle was facing the front - directly above the Direct Drive - and went to work printing THOSE five squares. Now here's where things get interesting. I thought I had my Bowden + Linear Advance dialled-in like a sweetheart. Going Direct Drive proved me wrong. Or, at least, it proved the limits of a Bowden setup. See, straight off the bat I could see I was over-extruding. One wall test later, I dropped my previously perfect 100% flow rate in Cura to 80.40% and saw a huge improvement in print quality - and this was with Linear Advance disabled (M900 K0 in my start gcode). Wow. I always knew my flow rate, when calibrated, should be around 80% but I'd get wall delamination at that rate under a Bowden - but not with Direct Drive. Double wow! Now this makes perfect sense, because there's impossible-to-remove play in a Bowden setup - even with Linear Advance. And that's something Direct Drive can't suffer from. And the difference in quality and dimensional accuracy speaks for itself. Linear Advance was the first "upgrade" I did to my printer (a soldering mod to the motherboard). It was fantastic when dialled-in. Direct Drive beats it. As far as I'm concerned, the age of the Bowden rig is over. Just be sure to dial-in that retraction distance and speed. It makes a whole new world of difference.

I honestly didn't know what to expect from this kit; I was pleasantly surprised in what I found... The kit comes very well packaged, labelled correctly and has a very easy to follow instruction manual. I would advise you pay close attention to your specific hot-end when disassembling it; there may be additional features such as sensors you may need to orientate correctly. The bracketry is fairly well made and heavy duty for the application (0.105" thick). The hole accuracy is good and the black finish blends well with the machine. I decided against using the supplied Bowden tube as a length of capricorn tube came with my new extruder mechanism. The supplied cable extension is of sufficient quality to work, although I don't like the idea of have more connections in line than necessary. I decided to re-use an older X axis cable I had laying around. The cable ties and re-useable velcro straps are a nice touch and made the installation that much easier. NOTE: The spring adjustment screw on the extruder mechanism cannot be tightened once installed, consider changing the screw for a standard bolt (which is supplied), for access with a spanner. Overall, this is a fantastic value for money mod, that has very few comprimises. Beware that the install may not be as easy as you might think; order of operations is important.

Easy to install and set up, it's just a pity that all the parts you need to fully upgrade your 3D printer to direct drive is not available as a kit, but all the parts are available separately.

Install went perfectly ok, and parts seems to be of good quality. I really don't understand the reviews stating that the spring arm bolt is in the way of the motor mount screw. It's not hard to work out that you put the motor mount screw on to the hole first, then insert the adjustment hex bolt, and wind it right in so you can get the hex key in and tighten up. What I am frustrated about is that the description clearly says that a BL touch bracket is available. Upon asking the seller, I got a message back saying "we don't have a bracket". How did you take a promo picture with one attached then? I'd print one, but can't now unless I take everything back off again.

Saw this kit recommended over the official Creality kit because of the centre of balance and light weight. It works well for me, easy to install if you take your time and follow the instructions - which cover using it with different extruders.

Lieferumfang: Geliefert wird der Umbausatz in kleineren Tüten und mit einem (wenn auch in Ameisenschrift) verfassten Beiblatt. Umbau: Für den Umbau wird der X-Gantry (also der Teil, auf dem der Hotend sitzt) ausgetauscht. Also die untere, konzentrische Schraube lösen, das Zugband beiderseits lösen und dann abnehmen. Die neue Grantry im umgekehrten Prozess wieder anbringen... der obere Teil für den Steppermotor, der den Extruder bedient, wird ohne den Steppermotor auf die Gantry gesetzt und dann - entsprechend des Handbuchs und des vorliegenden Extruders - auf die entsprechenden Bohrungen gesetzt und festgezogen. Steppermotor wird mit dem Extruder festgeschraubt. Fertig. Mit etwas Selbstvertrauen und ggf. Erfahrung eine Sache von unter 10 Minuten. Der Umbau ist, wie schon gesagt, ÄUSSERST einfach und dank der Tatsache, dass das Ding aus Metall ist, auch steif und robust. Vorsicht allerdings, wenn man einen selbstgedruckten Fan-Duct (also das Teil, dass das Hotend umgibt und mittels Lüftern mit Luft zum Kühlen versorgt. Dadurch, dass die Schiene, auf dem der Extruder sitzt, etwas übersteht, sind größere Ducts (wie mein "Original"-Satsana) nicht kompatibel. Ich hatte allerdings einen Remix des Satsanas mit zwei Part-Cooling-Fans und musste nichts weiter machen, als den linken Lüfter zu entfernen, was dem Druckbild aber nicht schadet. Da ich zudem ein Dual-Z-System habe, kann ich wenig darüber sagen, ob die Gewichtsverteilung vorteilhaft ist oder nicht, weil beide Seiten der "Querstrebe" von einer Schraube gehalten wird. Die Druckqualität hat sich aber merklich verbessert, daher kann ich das Kit empfehlen.

ダイレクトにしたことでフィラメント交換が本当に楽になりました！！ もっと早く交換しておけば良かったと思いました。

Very easy installation with the provided manual. Works as expected.

Para mi Ender 3 V2, embona perfectamente y trabaja como lo prometido, si. Duda un producto de calidad y cumple su cometido. Debo decir que sus instrucciones en video son un poco básicas. Yo, con un conocimiento en mecánica tube dificultades menores, no bajo la calificación ya que es falta de conocimiento propio. No es una instalación que no esperemos hacer al hacer este cambio de extrusion.

This was apparently in my case so pretty unique: At the last step you see that the fan holder does not quite fit on the bracket, the holes do not exactly match. But If you are going to file a bit, it fits perfectly. Furthermore, if you have bimetal hotend then you have to take into account recommended 85mm that it should be shorter. I am very positive about the seller and highly recommend it. This item is better than the original directdrive that Creality sells.
