CrealityEnder 3 Dual Z-axis Upgrade Kit with Lead Screw, Metal Power Supply Holder and Stepper Motor 3D Printer Screw Rod Kit for Ender -3 Pro/Ender 3 V2/Ender 3 Neo/Ender 3 V2 Neo

Other than the poor instructions, the kit is great! Since installing, I haven't had any "spaghetti" prints, and prints are coming out very well.-the only thing I wish it had was a timing belt to keep the 2 screws synchronized, but so far I haven't had any issues with them getting "off". I could not find a kit that had the additional motor/screw, AND a timing belt and sprockets, but I see that I can buy a kit that has the 2 longer screws, sprockets and belt.

This was a very easy fit to my E3 v2 Neo. Directions not that great, but some common sense and youtube watching and you will be all set. Has everything you need to get it connected and running. Took the slop out of my gantry and produced better prints.

the y splitter cable that the kit came w is not compatible. I went to see if i had misplaced an adapter somewhere. After going over the box, it became clear that the cable i have is wrong. ☹️ Besides that all the mechanical parts look good!UPDATE: all bad y’all, i just realized that i needed to hook up the y axis splitter straight into the mother board, before doing any prints post-set-up i highly recommend making sure the x axis gantry is lined up & the bed i leveled out accordingly

Big fan of dual motor Z-axis. It was the difference between "ok" and "great" for my scratch built.What the He11 am I supposed to do with the extra wire? I finally just plugged in all three ends, then just folded wire and zip-tied until it all routed nicely. Great product, worth the price I paid, but the cable started to make me quite frustrated.

This is the 2nd time I have purchased this kit. They make your prints that much better. Its inexpensive insurance agains z-wobble. Easy to install, just takes about 10-15 mins.
