Print has jumped in X and Y axis?  

RE: Print has jumped in X and Y axis?

The good old layer shift... 

A whole bunch of reasons why it might happen:

• Pulley screws on X or Y motor not properly tightened. One has to be tightened against the flat side of the motor shaft!
• Belt not correctly tightened. Use this tension meter to get it right: https://www.prusaprinters.org/prints/46639
• X carriage over-squeezed. Loosen the back plate on the X carriage axis. (only relevant for Mk3S)
• Nozzle hit an obstacle. Some patterns such as grid have lines that cross within one layer. This can lead to little pile-ups at the intersection points, in particular if you have slight overextrusion, which in turn can lead to the nozzle catching at those pile-ups. See https://help.prusa3d.com/en/article/infill-patterns_177130/
• Zip ties on the wire bundle on the back of the extruder not properly positioned, so they or the cables hit the model.
