These are 4 start anti-backlash nuts though I couldn't see this in the description. They don't fit Ender 5 pro, new version, which has 2 start lead screws, and probably don't fit others. Please check before ordering

Installed really well on and Ender 3 Pro. I've noticed after modifying just about every system on the printer that as my tolerances become tighter and tighter, general shortcomings in the design start to become apparent. I'm not saying the Ender 3 Pro isn't a great printer at a fantastic price - it most definitely is! It is the definition of a truly extensible platform with unlimited possibilities. My modifications or "upgrades" are too numerous to list ad nauseum, but I have begun to see Z hops showing slightly uneven setdowns. This is due to not only play in the stock brass nut that attaches to the z rail, but general backlash by definition. The spring keeps constant tension between both parts of the anti-backlash nuts and the locking tongue and groove disallow either from turning in reference to each other. The slight gap allows the transmission of force applied in the opposite direction, which causes backlash, to the spring which compresses and decompresses thusly negating that force on the z axis and all the things attached to it. Viola... Problem solved. I ended up needing to put one set of m5 washers between the stepper's plastic attachment block and the frame to correctly line up the leadscrew with the center of the hole in the z axis plate. Doing this happened to align dead center. Two of the four mounting holes in the top half of the part lined up well with the existing holes on the z axis plate. Easy installation and very pleased with the results. If something should go awry in the future, I will update this review as I always do. Would recommend and would buy again. I haven't tried the couplers yet, although I'm maybe not the biggest fan of the set screw design... But I bought this set for the two anti-backlash nuts and the couplers will go in one of my parts boxes for another day.

J'ai dû pour diverses raisons monter et démonter plusieurs fois mon axe. J'ai pourtant fait attention mais une patte de maintien en laiton a cédé... Un peu déçu de l'achat.
