While installing my dual Z rod kit for my Ender 3, I noticed something I had completely missed. From the looks of it, I think my Z 2040 extrusions are bent? When I look at the printer head-on at the bottom the Z extrusion sits flush with the Y extrusion shown below:
However, when I then look at it head-on at the top, the Z extrusion does not sit flush with the 2020 extrusion mounted on top shown below:
This is the case for both Z 2040 extrusions. Does this mean my extrusions are bent? How would this affect my prints? Would I need to buy replacement 2040 extrusions or is this fine?
