    Got mine yesterday (7/17/2019) and even with no printed install instructions available I had very little trouble installing it. You do have to be careful not to lose the small parts and get the POM wheel spacers installed correctly on the second X-Gantry bracket but once you have these on and the eccentric nut adjusted for snug but smooth movement it’s great. I’ve seen a lot of negative posts from the know-it-all’s saying you don’t need this, it’s too expensive, and a bunch of other negative things, but folks, this thing solved a nagging problem I was having of the Z axis skipping a layer due due to the X gantry sagging on the un-driven end.

    Adding this and once I had both ends synchronized so the bottom ends were both at exactly the same height before tightening up the belt, it runs smoothly, makes manual bed leveling (tramming if you prefer) a bit easier (I don’t have an EZABL installed) and on the few pieces I’ve printed since installing it the vertical surface(s) are a bit smoother.

    In my opinion as a hobby user (I don’t sell my prints) Creality should have included this in the original printer in the first place. It may not be a MUST have, but it sure makes mine work much better than it did originally.

    Update to my earlier review. Since installing and getting everything adjusted right, including manual bed leveling, I haven’t touched any adjustments since. Everything is printing as close to perfectly as any of these machines can, and I’ve also found that I am now getting outstanding adhesion to the glass bed without any adhesive at all. I did a very thorough cleaning with dish soap and water plus followed that up with a denatured alcohol bath to make sure the glass was squeaky clean. Since that, an occasional alcohol cleaning has kept it working great. Haven’t tried ABS yet but I suspect that WILL need some adhesion help considering the high rate of warping with ABS.

    Before installing the Dual Z Axis mod from TH3D, I had to re-level every several days and had to use Layerneer’s “Bed Weld” to get things to stick. Hopefully won’t need any more of that except for ABS.

    This upgrade is amazing! I was constantly fighting my X-gantry level since building the printer. Install took much less time than I expected, and the instructions from the forum were helpful. First layer z-offset is much more consistent now. I also did not realize how much this upgrade would improve print quality. There is virtually no z-banding now, and the external perimeter surfaces are super smooth. This upgrade is an absolute must for your Ender3. Thank you TH3D!

    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.

      You can set the PSU on the table next to the machine or we have a page with all the STL files to relocate all the variations of PSUs on these machines: https://www.th3dstudio.com/knowledgebase/ender-3-dual-z-kit-psu-relocation-stl-links/

    Direct Drive and this. Nothing better!

    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!

    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. Only real issue is I had to switch out the upgraded coupler I had on it for a solid one because it was slowly coming apart during prints.

      Will this work with the micro swiss direct drive kit, not interference problmes?

      The kit installs on the rear for the main parts and you can place the belt tensioner facing the rear as well to avoid collision with the extruder when at higher z heights.

    Didnt really need to get this but thought i would try it out. I use a Bltouch and had minor problems with gantry level but was able to adjust the wheels to make it work. I thought i would the dual z out and it works better than i could hope. This turned from a item i dont need to something i am glad i have. It was easy to install (took time to do it right) and now my Ender 3 is works flawless on every print. I will be buying another one for my other Ender. This is something that Creality needs to put as stock.

  10. Question

    James

    I’m running a 400XL extender kit and was wondering if it’s possible to get belts of other sizes? I would rather do that than to spilt my Z cable to run two steppers off my SKR Mini E3

      Sorry but we only carry the belt that fits the stock printer.

  11. Question

    Jeff Sparks

    This is going to be my next upgrade. Would it be useful to also install the anti backlash nuts on both sides or is it less of an issue with the dual screw?

    • Tim Hoogland

      Much less of an issue. If you have the antibacklash already put it on the motor driven side. Only one of those is needed.

    The kit does exactly what I needed it to do, remove the cant of the X axis bar. The directions are minimal which isn’t a big deal as it is rather intuitive to put together. My biggest complaint about the product is the Dibond support for the tensioner pulley. I was expecting a higher quality of material for this piece, i.e. an anodized aluminum plate. The finish work on the Dibond was awful. It looked like it was hand cut and not done very well at all. I cleaned it up but I will probably find someone to make a new plate for me as it is embarrassing to have this piece of aluminum covered plastic on my pride and joy.

    The print quality is of my machine has been greatly improved though.

      Thanks for the feedback on the tensioner part. Would a printed adapter plate be preferred if done in ABS versus the ACM part?

    Is this a better solution for eliminating X gantry sagging than a second stepper w/lead screw? Thx

      We definitely think its a great solution and less work to install. The other solution will not keep it from getting out of alignment like this will. 🙂

  14. Just what my printered needed and easy to install!

    JimH (verified owner)

    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!
