11 Level the X Axis

  • Measure the distance from the X-axis smooth rod to the Z-axis upper connectors on the right and left side of the 3D printer.
  • If the measurements are not equal, manually rotate the right threaded rod clockwise/counterclockwise until the right hand measurement matches the left hand measurement.
  • Verify the leveling of the X-axis by measuring the distance between the X-axis smooth rod and the Z-axis upper connector on the right and left hand side of the 3D printer. Repeat the above steps until level within +-1 mm.
