Modification Z-HOME Standard line

The height, often called “Z max,” in your 3D printer represents the distance between the print nozzle and the print bed when the printer is in its reference position, known as “zero” or “home.” This value is a critical part of calibrating your machine and must be corrected to ensure optimal operation.

When you turn on your printer, you can find the height value displayed on the monitoring screen among the various data shown. This value is referred to as “Z” and is important for setting up the printer correctly before starting a 3D print.

As the height value varies, the following scenarios may occur:

To manually change the height or Z max value on your printer, follow these general steps:

  • Make sure the build bed is positioned correctly and clean the nozzle.
  • Return the printer to the starting position, “autohome”, so that it is in the reference position.
  • Go to your printer’s “PREPARE” menu. Depending on the version, you may find two options:
  • “Modify height”
  • “Modifica Z max” (Set Z max)
  • Select the correct command to change the height or Z max value.

The screen will allow you to choose a scale value at the top, usually between 10mm, 1mm, and 0.1mm. This will determine how far you want to move the nozzle along the Z-axis.

  • With the scale value set to 10 mm, turn the control knob so that the nozzle drops approximately 20 mm from the print bed.
  • Click the knob once to select the scale value at 10 mm.
  • Next, with the scale value set to 1 mm, turn the control knob so that the nozzle drops to about 2 mm from the print bed.
  • Click the knob once to select the scale value at 0.1 mm.
  • With the scale value set to 0.1 mm, turn the control knob so that the nozzle drops approximately 1 mm from the print bed.
  • Click the knob twice to activate the “SAVE Z.”
  • Turn the knob again to bring up “OK.”
  • Click the knob to confirm and save the new Z max.
  • Your printer will exit the command and automatically return to the starting position.

If necessary, complete the calibration using the “Manual Leveling” command in the “PREPARE” menu, adjusting the plane so that it is uniform in all positions.

Remember that the exact procedure may vary depending on your printer and firmware; So, always consult your machine’s specific manual for more details.
