Ender 3 Accessories Dual Z Axis Kit Lead Screw Dual Z Stepper Motor Upgrade Kit for Creality Ender 3, Ender 3 Pro, Ender 3 V2, Voxelab Aquila 3D Printer

I received this yesterday and installed it today I think it will prove to be a great upgrade to my Ender 3 as the Z axis is quite a heavy piece of moving part on the printer and the additional help of the second stepper motor must surely help keep the axis even - we shall see the first print in progress.The upgrade kit is well packaged and comes with nearly everything you need to do the job and does not take long to complete and doesn`t require major strip down of your printer. The instructions are pictorial and stepped and are easy to follow.The ONLY THING WRONG is that when you go to re-install the power supply onto the brackets supplied there are no holes in the PSU at the back you need to drill a pair of holes and attach the unit with a pair of short self tapping screws. The instructions step 12 sadly just ignore this inconvenient truth and leave you to sort this one out yourself. Hence not the 5 stars it deserves.I shall post this now and upload my benchy test boat image when it has printed.Photo 1 shows bracket in place behind the psu with no holes in the PSU skirt for it.Photo 2 shows the bracket secured to the PSU skirt using self tapping screws.

Poor instructions, but that wasn't a big deal to me. It may well be to others. Mechanism is all a bit "Meccano" with no precision anywhere and the lead screw nut hanging loose off its bracket. The biggest issue is that it is not possible to use it as both of the servos rotate backwards, so it tries to home by going skyward. That is because the splitter cable socket is wired mirror image to what it should be. This should have been a nice upgrade, but attention to detail lets it down badly. Clearly they don't bother with any sort of QC.

Easy to fit, great value for money. A must have for DD converstions
