I recently replaced my aging but well dialled in FLSun Q5 with an Elegoo CC2.

I am very pleased at being able to print much larger things, but I get this effect at height. This is an egregious example but even cleaner prints still have obvious layer shifts.

    I had a problem at an exact height every time and it was a tiny bit of dirt on the z screw. I couldn’t see it because it was a white wisp of filament in the threads but after a cleaning and lube the problem went away.

    I should say, I have so far changed to scarf joints, changed to normal z-hop and increased a-hop height.

    I also increased brim size, even though I had no evidence of lifting.

      Just seeing this. If you really think this isn’t warping print a cylinder tower in the spot where this parts messed up edge was on the bed. If that prints with an issue in the same exact height, it’s a problem with your mechanisms, likely z axis.

    The fact that it is just one side and not even across the z axis tells me that side lifted from warping. Clean your bed with soap and water, use a brim, and if those don’t work slow the print down. Long straight lines are prone to warping.

    X axis is off.

    Yes. The left to right. Not top to bottom (z)

    When the x axis is off, the auto bed leveler can compensate for it. For a while. Until it gets high off the bed.

    Then the skew becomes more problematic as the height increases.

    Basically you need to adjust your x to be level on both sides. One side is higher/lower than the other. Probably by 1-2 mm or even less. (On the z rods).

    Now I know how to do this on an ender 3 v3. But not your model.

    But here is a link to the ender one so you can better understand the issue and how to fix it.

    I recommend looking over some of the comments to help explain this issue better and why it’s causing the problem you are seeing.

    Alternative cause:

    If the print is lifting from the plate it can cause a similar issue but those errors would likely be closer to the bottom. But not always.

    Is there any lifting or warping of the bottom of the print ?
