DawnbladeEnder-3 Dual Z Axis Upgrade Kit with Lead Screw Stepper Motor, 3D Printer Upgrade Parts for Creality Ender-3 / Ender-3 V2 / Ender-3 Pro/Voxelab Aquila

This kit was fairly easy to install, kind of fun if you like working on stuff. It has a few extra parts for a "non-NEO " ender 3 that don't get used but this doesn't cause any issues.I also purchased a "3D Printer Dual Z Axis Lead Screw Aluminum Kit Timing belt width 6mm Gear 20 teeth for CR10/Ender3 Series 3D Printer" kit from AliX for $10, I highly recommend adding a sync belt kit and true your x gantry to your bed; the sync belt will keep it true, unless you mess with your bed leveling screws...

The z screw straight, the nema motor standard, and the aluminum parts to spec, and even an extra thrown in. It did seem to be a little thinner aluminum than other kits I've seen, but they work for this use case without issue, not being flimsy by any stretch.While it's argueable if a backlash preventer is valuable on this type of printer, If you're going to do it anyway you might as well get this double z kit which basically gives you that for free. This kit was also less expensive than the official creality kit, so double bonus.I never use the PSU mounts that are included with these kits, only because I like to relocate the PSU differently, however this mount would have been adequate.

As the title says, decent kit. Went together well for my old E3v2. Substantially reduced X axis droop. Only two complaints. The motor that is supplied isn't a Creality motor and I must have gotten a bad one, because I already had to replace it a week in. Thankfully I have spare parts laying around.Second, the idler bearing to reduce z screw play is nice, but it's NOISY. Mine chatters like an old woman. That very well could be a bent screw (which it rolled perfectly on the counter top when I installed it...) or just my luck. Like I said, neither are show stoppers and the kit performs what it's meant to do, just that motor really annoyed me. I am sure I have a bag of Timken 408 bearings around here somewhere that I can replace it with, it's just kind of annoying that I buy something and then have to fix it.At any rate, I would buy this kit again.

Installation took a good while longer than I expected, due in part to the included instructions not being very helpful. However once I got it figured out, everything went smoothly and feels solid.After leveling & calibrating my print quality has notably increased, and a couple issues I've been fighting for months disappeared. Overall very happy with the kit.

La instalación fue rápida y sin mayores complicaciones, he obtenido buenos resultados.
