Layer Shift

Just a heads up that this isn’t a layer shift. A layer shift moves the entire model away from its origin because of a step loss. There are also other reasons. A layer shift doesn’t return to its original position several layers up. It stays shifted. It also isn’t only on one face. CoreXY machines shift different than Cartesian machines. Generally cartesian machines shift in X or Y while CoreXY shifts in a combination of X and Y.

What you’re seeing here is the material shrinking when it it printing the inside top layer. The larger amount of plastic pulls the edges in as it cools. When the walls are printed on top of this they print in the original position which shows as a step because the part underneath of them has shrunk in.
