Creality 3D Official Printer Ender 3 Dual Z-axis Upgrade Kit with Lead Screw, Metal Power Supply Holder and Stepper Motor, 3D Printer Ugrades Kit for Ender 3, Ender 3 Pro, Ender 3 V2

Installs well, nothing too complicated. I did notice a marked improvement on overall quality, especially when things get tall. it makes tramming the bed much more consistent, and if you add this to the yellow spring and aluminum adjuster wheel upgrade, you shouldn't to ever tram it again.

Work as expected, everything needed to install it is included

Good directions and everything was a perfect fit. Was difficult to get perfectly level but has stayed pretty solid. Reduced z banding a little bit. Worth the money.

That added z stability really helps on the older ender3

I combined this upgrade with the Sprite Extruder Pro at the same time because i was worried about the extra weight of the new extruder on my plain single Z-axis Ender 3. So because i did 2 upgrades at once, i don't know if this kit had any effect on print quality since the extruder upgrade definitely did improve things. Based on my printing experience you don't need this kit by itself. The original extruder on a stock Ender 3 is going to be the main hardware holding back your print quality. But if you upgrade the extruder, you should probably get this kit too, and definitely get it if the new setup is heavier. I thought installation would be a lot easier than it was. I was expecting an adapter cable to plug into the existing original Z-axis cable as an extension but you actually get an entire new Z-axis cable that plugs into the mainboard. So that means opening up the mainboard area. I had no intention of leaving the original cable in there unattached so i also had to undo the wire bunch to remove the original one and wrap it all back up again. The assembly instructions are extremely minimalistic so i'd recommend watching a video first. I had to take apart the carriage to attach the new rod plate but the worst part was aligning the entire gantry when there's now two separate rods. The rods have to be aligned both to the frame and to each other. Keep in mind that you probably can't move the gantry by hand anymore because i really doubt you can turn both Z-axis rods at exactly the same speed. So now when moving the gantry for any reason you have to power up the motors and do it that way to keep the alignment in sync. It's a bit annoying (but obviously worth it). It took me longer to install the dual Z-axis kit than it did to do the entire extruder upgrade.

Fixed a side to side say the machine had developed. Recommend for anyone with one of these to avoid it eventually happening.

I was skeptical about the necessity of this kit, but it has been a game changer. I installed this on an ender 3 pro. Since I installed it have not had to relevel my bed. I have notice less artifacts even with printing at 200mmps. Installation is a little involved but it is pretty straight forward.

Tenía problemas de nivel cuando solo tenía 1 eje y constantemente se caían los soportes, eso acabó con un doble eje z, si comprás la ender 3 DEBES comprar esta actualización.

The kit doesn't work for the Ender 3 Max, as the lead screw is too short, however the mounts and accessories fit. Had to buy a separate lead screw that was longer, but once I did that, it fit beautifully. Was easy to assemble, despite there being NO instructions in the box whatsoever. Thankfully I found a video to confirm my steps, but bags were not numbered, and mostly labeled in Chinese. Just make sure when installing you watch a YouTube video to confirm your steps, and when dealing with the concentric nut, make sure it goes back in the right way or your pom wheel won't work.

Installed on ender 3 max with 500mm z rods

Se lo instale a una Ender 3 v2 y ahora imprime con mejor calidad aunque tuve que ajustar el z offset.

I recently purchased this upgrade, and I must say that the quality is overall solid. However, I did notice that the instruction guide was a bit blurry and challenging to read; I have no idea if it is just for me. Despite this minor issue, I found this upgrade very useful and practical. I would recommend it to others who need a dual Z-rod upgrade.
