Recalibrate the Z-Axis

 

To ensure your printer is ready for printing:

  1. Spread grease on the lead screw, if needed.
  2. Manually move the stage up and down to disperse the grease.
  3. Ensure the print stage can move the entire travel span of the Z-axis.
  4. Start the Shim Bed Level utility
  5. Use the Plastic Shim to check the leveling at the first thumb screw. If the level seems good, skip to step 6. If the leveling seems off, please follow the next steps:
    1. Attempt to adjust the thumb screw to obtain a good level at the first point. If there is enough travel in the thumb screw to attain a good level at that point, continue with the leveling process and skip to step 6.
    2. If the print bed is too close or too far from the print head to accurately level the print bed, please run the Z-Offset utility.
      Note: To access the Z-Offset utility, go to "Menu" -> "Bed Level" -> "Adjust Z-Offset".
  6. Run the Bed Level Test Print and confirm that the bed is leveled correcly.
