Put the unit together and all seems to fit apart from Id say the belt it maybe 1 or 2 teeth short as when I run my gantry up to the very top the stress on the rods is too much for the motor and it skips steps, but if Im only going up to 190mm high its working great, maybe over time the belt will loosen off a bit. It was also missing t-buts for the upper middle belt tensioner (which is not really needed as the belt it probably too tight rather than being loose enough to need a tensioner). lead screws are nice and straight and the bracket to fit onto the RHS of the X gantry fits great. I did have to design and 3D print a piece to fit under the RHS rod bearing holder to stop the RH lead screw - I added a photo of it (printed in white with an M3 nut and bolt.

Flawless. Parts fit very well on my end 3. The timing belt is a bit short. You don't need the belt tensioner.

Einwandfrei. Teile passen sehr gut an meinen Ender 3. Der Zahnriemen ist ein bisschen kurz. Man benötigt den Riemenspanner nicht.

It does not come with instructions but any skilled DIYer could manage it. Check some YouTube videos if necessary. All the items required are there. The belt need to be put in place before installing the geared pulley, because the belt is not very stretchable. Make sure that the 2nd Z screw is aligned as much as possible to the frame and loosen up the T8 nut which will help with the screw wobble. Do not forget to put some grease on the screws.

The threaded bars came straight, despite the packaging not being the best. The pieces had not been stuffed. There is a lack of paper instructions. There are videos on the internet of how to mount it even though printed instructions would have been handy. the printer with this modification no longer has the problem of synchronism with the double Z axis. I recommend the purchase.

le barre filettate sono arrivate dritte, nonostante l'imballaggio non fosse dei migliori. i pezzi non erano stati imbottiti. mancano le istruzioni cartacee. su internet si trovano dei video di come si monta anche se delle istruzioni stampate avrebbero fatto comodo. la stampante con questa modifica non ha più il problema di sincronismo con il doppio asse Z. Consiglio l'acquisto.

I didn't take a assembled photo, but it works wonderfully! Unfortunately, my Ender 3 is rarely in use since I bought a new printer, but if I need to print more, I've already run both at the same time. I am satisfied, good quality, top!

Ich habe leider kein zusammengebautes Foto gemacht, aber es funktioniert wunderbar! Leider ist mein Ender 3 selten im Einsatz, da ich mir einen neuen Drucker gekauft habe, aber falls ich mehr drucken muss, habe ich schon beide gleichzeitig laufen lassen. Ich bin zufrieden, gute Qualität, top!

Great product. Mine is fine but sticks came without any box. Luckily they didn't bend on the shipping.

Good update for my Ender 3V2. The installation is easy and fast. I have added two axial ball bearings so that the second thread spindle cannot slip in the bearing.

Gutes Update für meinen Ender 3V2. Der Einbau ist einfach und schnell gemacht. Ich habe zusätzlich noch zwei Axialkugellager eingebaut damit die zweite Gewindespindel nicht in der Lagerung rutschen kann.
