Possible causes for the printer not printing correct dimensions:

  • Incorrect number of steps/mm in firmware settings
  • Belts are not tight enough
  • Pulley slips on the shaft

Looking at the picture, I would go for the first case, because distortion looks regular. Try checking microstep settings on your board, and settings in the firmware.

This could be because your belts are either old or not tight enough. Try adjust or replacing the belts and try again.
