XYZ-Axes Offset Calibration

Model [•] Hylo.01
Category [ ] Installation [•] Operation [ ] Maintenance

Summary

The procedure that follows gives instructions on how to calibrate the T0 and T1 relative positions along the XYZ-axes. Well-calibrated XYZ toolhead offsets can prevent poor first layer adhesion, shifts and other print defects caused by misalignment.

AON3D recommends calibrating:

  • the Z-axis before every single material print;
  • the XYZ-axes before every dual material print.

Estimated time: 15 minutes

Prepare the Machine

  1. Install the hotend on the toolhead assembly that has a nozzle size that matches the print profile. Refer to Replace Hotend.
  2. Make sure the nozzle is clean:
    1. On the graphical user interface (GUI), navigate to the Home tab.
    2. Select CLEAN POSITION
    3. Make sure the nozzle if free of debris. Use a wire brush to clean the nozzle if necessary.
  3. Repeat steps 1 and 2 with the adjacent toolhead if necessary.
  4. Install a bed sheet. Refer to the Install Build Platform procedure.
  5. Close the door.
  6. Preheat Build Chamber and Bed:
    1. Select Files
    2. Select the filename to print.
    3. Select PREHEAT.
    4. Wait for thermal equilibrium.

Z-Axis Calibration

  1. Navigate to the Calibration tab.
  2. Select CALIBRATE.
  3. Wait for the probing sequence to complete.

XY-Axes Calibration

If a print uses the two toolheads for the same print, the toolheads must be calibrated along the X/Y-axes before a print is started. The X/Y-axes calibration procedure adjusts the coordinate system of the two toolheads to be in line with each other.

The inspection drawer components overheat if left at chamber temperature over 80°C for extended period of time. The drawer will close automatically 120 seconds after opening to prevent overheating when chamber temperature is over 80°C.

  1. Navigate to the Calibration tab.
  2. Select START XY OFFSET.
  3. Use the distance adjustment buttons to center the nozzle to the crosshair.
  4. Select SAVE OFFSET AND START NEXT TOOL.
  5. Repeat steps 2 and 3 with the adjacent toolhead.
  6. Select SAVE OFFSET.

Evaluate the First Layer

The Z offset calibration can be adjusted in minute increments while printing to help get the correct first layer:

  1. Select the Calibration tab.
  2. Under Bed Mesh select 0.2, 0.1 or 0.05 mm increment.
  3. Under Bed Mesh, select UP or DOWN to adjust the distance between the build platform and the nozzle.
    1. Select UP to increase the offset between the build plate and the nozzle.
    2. Select DOWN to decrease the offset between the build plate and the nozzle.
