On a stock Ender-3 the X gantry is driven at one end only, so the far side is carried by its wheels alone and tends to settle a fraction as the machine works. This kit adds a second lead screw and drive on the opposite upright, holding both ends at the same height. You see the difference on tall prints: banding down one side of the model eases off, and the gantry no longer needs nudging back to horizontal after a heavy job. It fits the Ender-3, Ender-3 Pro, Ender-3 V2, Ender-3 Neo and Ender-3 V2 Neo, with brackets and fixings included.
Good for
- Tall prints with visible Z banding
