shifted

A few hours into a print I checked and the whole thing had shifted.
Anybody know what causes this?

One of your axis motors skipped, likely because the hot end got caught on an overhang that curled up.

There really aren't any overhangs to curl.
I'm going to print a cylinder and see if it slips at about the same height.

Watch out to see if the bowden tube didn't get caught on a cheapskate. If it snags for a second it will cause the belt to skip a few teeth and shift the print over.

Right, maybe not overhangs, per se, but I can definitely see areas of the print where stray pieces of plastic are curled upwards and could interfere with the tool path. But as Holy1 mentioned, it could be some other physical interruption of the tool path.

An axis motor skipped. You will have to determine the exact cause.

If the belt isn't trim enough it can get caught when the print rises quickly and if the belt isn't tight enough it can slip. If the print surface wasn't layered smooth enough with fresh glue..sometimes too much glue can offset a lump in the layers printed and end up making plastic balls/lint that the nozzle can trip over and if the trip is big enough the print arm can lose it's place for the rest of the print.
