Layer misalignment is generally caused by missed steps. There are a few common causes:

- Stepper driver adjusted too low
- Belt too loose on stepper gear.
- Extruder nozzle hitting the object while printing. (part lifting/curling)
- Interference in motion of the X or Y carriages.
- Attempting to print outside the physical X/Y limits (switch engaging)
- Error in gcode (uncommon)

Hope this info helps!

Also anything jamming the movement. Stray end of the belt or a wire.
Also the drive gear on the motor slipping.

I have changed stepper drivers now it works OK
