Say no to elephants foot, inconsistent first layers & Z banding. This is the ultimate z axis rebuild / upgrade using brace rods, Oldham couplings, dual z screws & thrust bearings.
You can see quantifiable results before and after the upgrade. I will show you the what, how & why of every upgrade. After this you can forget your z axis troubles once and for all.
This video is a part of my Ender 3 upgrade / rebuild series. Do check out the previous videos for all the upgrades and mods.
