Print jumps 7mm in Y direction after initial layers

Doing a quick ebay search, do the Kysan steppers you bought from ebay have the Kysan branded sticker on them? There seems to be two, one without this sticker and one with.

I bought one from the 3dmakerworld seller. Their picture doesn't show a Kysan sticker, but the motor came with one. Although I do have to chuckle - it looked like a label anyone could have printed and stuck on the motor.

These motors all tend to look the same, but one obvious thing about this one I found impressive is the wire gauge. It's marked #22, compared to the #26 wires on the OEM motors from MakerFarm. Heftier wire should mean less resistance, leading to more power being applied directly to the motor. I'm not sure that difference in the motor specs alone would have justified the increase in wire size for the Kysan.
