Creality 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 3D Printer

Works perfect and pretty easy to install. Great upgrade for my Ender 3 pro.

Was having some z axis issues with and ender 3 pro that had some extra weight on the gantry. This was a perfect solution to making it a little more stable. The instructions aren't great, but the university of YouTube has plenty of install videos.

This is one of the best upgrades that I did to my printer. I was stuck with an ender 3 pro with BL touch and an 8 bit board which made the BL Touch almost useless. I got the Creality 4.2.7 board with silent drivers and touch screen and it was all plug and play. Great directions and pictures help me with getting it all installed and printing a Benchy in less than 2 hours. The printer sits next to me on a wire shelf and I have to look to see if it is still printing because of how quiet the stepper motors are now. I would recommend this to anyone that has an Ender 3 pro with the 8 bit v1.1.4 board. Time saving tip wire the runout sensor and use it. It has saved many of my prints from being victim of breaks in the filament or just running out all together.

The first package I had received looked to be an open return,Amazon quickly rectified this and I now have the complete part kit. The only gripe is that the z-axis support bearings, that attach to the top, do not fit the ender 3.

Not sure if it really helps the print quality, but it certainly has not hurt it! does seem to help on larger (wide x) prints as layering is smoother. we made couple other changes same time, so they all help some. Glad we made this upgrade.

Identical to original Z axis motor and thread rod. Includes Plug-n-Play wiring, no software changes were needed. Did not come pre-lubricated like original did. Recommend lubricating from the start.

Installation is pretty easy but this kit lacks two things.1. Leveling jigs for the rail.2. Syringe for greasing ball bearings.I was able to find printable jigs and ordered some syringes. During installation I discovered that the stock belt on the E3 Pro is a couple of mm short and I had file the end of the x axis tensioner to make everything fit. Also the rail extends the extruder about 8mm so you have to account for that in your configuration.

If you're thinking about getting it, I would do it. Pretty cheap and relatively easy to install if you can infer from the 6 low-wuality pictures they provide in the "directions." Either way, once its going and level, its plug and play and makes your layers way more even. everything is more level and its honestly surprised me. makes prints look much more like a 700 dollar printer than a 1-200 dollar one.

I didn't think it would improve as much as it did. With the dual screws and a CR touch, this printer even though it is a be slow, produces excellent prints.

When you by the sprite hotend this upgrade is nearly essential.

The good... The peices that come with this for mounting your hot end are great for flexible install weather you have the Sprite or the other.The meh... The placement is just off for the switches so you will need to adjust your end stop to merry up to the hotend mount to make it work.The ugly... I didn't get this installed till after the return period, but the shuttle was broken from the start as one of the alignment pins on the end piece was broken and causes the bearings to get caught when moving. Upon further inspection my unit was shipped with minimal balls in the shuttle which caused a fair amount of noise and grinding sound when in use. The lube provided was to viscous and caused binding with the bearings and caused some issues of binding. This lead to me having to clean the shuttle order new bearings and see the issues with the shuttle also the edges of the shuttle look chewed up and rough like someone beat it up before shipping.Do I recommend this product yes ... Just not from creality. It looks like a knock off product and for a bit more you can get a better quality

La qualité de la tige et du mécanisme semble aussi bonne que l'originale inclue avec l'imprimante. Seule chose à noter : le feuillet d'instruction d'assemblage est très sommaire et il est beaucoup plus facile de suivre les instructions vidéos qui sont sur la page du produit sur Amazon. Ne pas oublier de lubrifier la tige (lubrifiant non inclus !) avec graisse ou huile quelconque pour éviter le bruit et l'usure prématurée du palier fileté.

received the package on next day of order. Clean and lubed the bearings and rail, install the assembly using the leveling jig previously printed. Rolls smoothly but as soon as I tighten the gantry plate with the 4 bolts it starts to bind, had to add 2mm shims to the bolts to make it smoother but still not as smooth as without the gantry plate. seems like the bolts are too long and possibly hitting the ball bearings causing binding and/or gantry plate slightly warped. This kit comes with a MGN12C carriage which is slight small than the H carriage. Maybe if it came with the hardware for H carriage it would work better? Overall not super satisfied.update:Just rechecked the dimensions this is a MGN9C rail kit, description is wrong
