Good Dual Z Upgrade for and Ender 3 Pro with a V4.2.7 board. Wasn't difficult to install with supplied instructions. Only grip is the top bearing blocks are too tight and cause binding on my machine.

This is not the official kit as i believed it to be when i ordered it, but it does seem to work after some tweaks. After first installation I had some binding and Z lines. I did some adjusting of everything and it got better, but I still got some squeaking and binding. Eventually I removed the top bearings as it seemed they were causing my issues, and cleaned and re-lubed both Z screws and now its very nice, seems to stay in tram pretty well, squeaks and Z lines are gone. If you take the time to adjust and lube things.. and in my case remove / not install the top bearings its a good upgrade for the E3 when adding a Direct drive.

It may not be mentioned in the instructions, but the best way to install is assemble everything, then loosen each of the four frame bolts on the top on your Ender, two left and two right. Just loosen them enough so the frame can move a few mm in either direction. Raise your Z axis to its highest point then tighten. Use any sort of T type tool, a carpenters square or whatever, and for the new Z axis screw manually turn it to make the Z bar parallel to the top bar from side to side. For those who said to not install the screw guides, they are wrong. When Z axis it at highest point, put in the guides with a little bit of give. If you see the bearing of the guides at the top you installed it upside down. The bearing should be at the bottom. Take an hour or so and raise and lower your Z axis and loosen and adjust the frame and screw guides if you hear any clicking. After doing all of this you will have a kick butt setup, ready for direct drive extruder or whatever. Yes it does take some time, but it is well worth it and fun to calibrate.And to those who said they had to drill holes for the power supply, not sure wtf they were talking about. Everything fit perfectly. If you install the parts wrong yeah I could see why drilling holes would be needed. Just hold the supply in place and look and experiment with how the pieces should go together. Pretty simple to figure out.

I got this because one side of my Z Axis was dropping and I couldn’t get it straightened out. This fixed it with no issues but took a couple of tries to get the screws to sync. Everything you need comes with it. Only downside was that the screw stabilizer blocks that are supposed to go at the top to keep everything stead cause the screws to bind up so I couldn’t use them. Still, with the dual screws, it’s more than stable enough when leaving them off. It’s worth the money and the 30 mins to hook it up.

Installed this when I did the initial build of my ender 3 v2. The stepper is much louder than the stock stepper motors. Instructions are not for beginners, but there are good videos o. YouTube that help with the install.
