Layer shifting during print

Hello Everybody!

I have a problem with my printer, Creality Ender 3. The layers are shifting no matter what I do. I have another printer which works just fine (after I changed the whole hot end part to a new one), but this one I tried to fix and I just don’t know what to do.
The same print comes out fine from the other printer so not sd card or gcode problem. I fixed the belts, they are not loose. Also tried to fix the printers table so that it wouldn’t wobble while printing. What else to do?
I would buy any part and repair if necessary.
thank you

Layer shifts can have the following issues:

  • Belts not tight enough (or way too tight so that it’s hard to move)
  • Acceleration too high
  • Something is obstructing the axis mechanically from moving
  • Stepper motor current too low or damaged motor cable (drive the axis manually and slightly hold it with your hand, if it needs very little force until the motor makes a clicking noise that could be it)

I would check it in this order.
