That's layer shift, and there are two options:

1. The print didn't stick to the bed well, and while the newer layers were placed properly, the model on which they were placed was not where it should have been.

But this is most likely the second:

2. The head got momentarily hung, probably on part of the model, and so the head was not where the printer thought it was, and material was deposited in the wrong X/Y position from there upward; the same issue may have caused subsequent moves.I'm guessing there's no closed-loop feedback, so no detection of missed steps - correct?All you can do is watch the print and try and determine at which point the head gets hung on the model. It's possible that thicker layers and/or more cooling can fix this. See also:
