Layer shift? What causes this?
Since I finished building my CORE One, it seems to have layer shift issues on large or high infill prints. What could be causing this?
Example (70% gyroid infill).
Belt tensions are good, per the tuner.
You can see it had a couple small layer shifts, then the BIG one. Also, the layer before the big one, looks like it was printing on a curve...? Part was just a cube, all the previously layers were vertical/horizontal lines.
Help! Please and thank you.

Is your gantry completely square? Does the print head move freely to all corners and nothing is binding?

Forgot to add. When you run X and Y calibration, do they still pass?

This will be interesting, not only does it print the gyroid infill on a curve on top of a layer of straight lines, it follows the same curve consistently in that layer, that consistency throws me off. If the part lost adhesion I would expect much more of a mess, not consistent curves, if it bumped into something I would expect a shift and continued straight lines. If the part is oriented straight on the print surface my understanding is that both x and y steppers need to move go get a straight line, it is almost like a stepper is not able to keep up periodically, in any case it will be interesting to see what ends up being the root cause.

Is the "avoid crossing parameters"option set? Aside from the basics already discussed above, this seems to be the major culprit for layer shifts as it apparently generates such high speed directional changes that the printer loses it.
