Once installed and tuned, it eliminates most if not all z-banding and other gantry issues. I own two of these kits for my Ender 3s
I was going crazy trying to get the gantry to hang level on my Ender 3v2. After many hours of Google-Fu I came to the conclusion that I could either live with it or add a dual z kit. I almost bought an electric kit until I came across this one. I like that it’s all mechanical and I won’t have to worry about routing wires for another stepper motor. It took me about 20 minutes to go from unplugging the printer to plugging it back in and running a test print. Just to point out, there are other kits on that jungle-theme retail site that look like this one, but this kit comes with pillow blocks that have bearings in them. Look closely at the knock-off’s pictures.
The sagging axis on my ender bothered me, not only because it looked ridiculous, but it was causing other issues. Excessive wearing of the rollers from supporting a cantilevered beam, print inaccuracies, etc. But over time it became a pressing issue once it began to introduce variance and unpredictability. Sure, it’s a cheap printer, “it’s to be expected at this price level.” No it’s not, I’d call the level of movement and variability in that axis unacceptable. It made it so that even with ABL, first layers were all over the place. Some buried into the print surface, some not adhering at all. Glue on glass, really good surfaces worked, but felt like that was a band aid. I’d tram the bed, then post print do a bed visualization, and it would be wildly different. Heavy springs and witness marks on the fittings, the bed didn’t move.
This solved all that. Perfect and repeatable first layers, even layers across the bed, set it and forget it leveling. If nothing else it’s a cheap upgrade that should have been stock. Plus, if you’re in it to tinker, you’ll have to move the power supply, which brings about all sorts of creative options.
Removed the screws and added the standard spacers. Then did this dual z. Works like a charm! I bought the autoleveler previously but haven’t installed it because this solves my problem. No calibration needed, it really helps!
Installed this along with converting my Z axis to linear rail, and couldn’t be happier. No z sag and constant adjusting anymore. Thanks TH3D.
Easy to install kit everything fits, if your looking for an easy way to add duel Z drive to your printer this will do the trick.
I noticed my Ender3 gantry was starting to sag. Even after leveling and adjusting it just a few prints later it was sagging again. Following the instructions they provide on the support site, with lots of pictures, it was a quick and easy install. No more worrying about my X gantry being level. Thanks TH3D!
Works great on my CR-20 Pro, helped to improve the accuracy of my probe and removed any sagging of the gantry. It was a little bit of work to get everything aligned properly, but in the end, it went together fine.
Was a PITA for moi to get everything correctly aligned and squared and leveled. But worth the effort by far! My Z axis has never been smoother, with zero binding, even with the print head and DD motor over there, smooth as a babies bottom! Not surprised to see this fantastic and affordable upgrade sold out! Sooo glad I got mine already! Christmas will be a 3d printed gift year! Thanks for all the cool stuff, Tim!
was really easy to install. great idea to improve printer. Was dreading taking the gantry apart, again, to tighten up the screws. now I suspect it will be a non issue in the future.
