layer shifting

[rioz 0]

I got layer shifting in the printouts.  Model is rendered in Cura and looked ok.  But most of them will shift in X axis (shown in figures).  Anyone has experience on it and can share your solution?  Is a hardware or software problem?  Any method to check if there is a layer shifting (in Cura or gcode) and prevent it?

Hi there, 

 

Layers shifted that bad means the belt skipped a few gear's teeth. Check belt tension and if the belt and gears are clean.

Will it caused by step motor overheat?  I found the step motor (x axis) is very hot after printing an hour.
