[Sonic Mini 4K] Z-axis calibration

Z-axis calibration is essential for every 3D printer. Run this test to make sure that the building plate is leveled to the LCD screen. This is to ensure that models and prints will adhere to the building plate.

We will guide you through the steps of calibrating your Sonic Mini 4K LCD 3D printer by using a piece of A4 paper:

1. Z-axis calibration

Power up and Prepare

• Remove the resin vat and make sure to remove any objects present on the machine's platform.
  
  
• Attach the building plate knob to the printer and align it with the pins. Screw and tighten the building plate.
  
  Please ensure that the building plate remains stable and does not shift while tightening.

• Use the Allen wrench included in the toolbox to loosen all 4 screws on the sides of the building plate in a counterclockwise direction. After loosening it, double-check to see if the plate is loose and movable.
  
• Pull the building plate in a downward motion until the screws on the building plate have been pulled down completely.
  
• Place a piece of paper  (roughly 0.07-0.10 mm) on the LCD

Please use 3 sheets of A4 size paper if you are using ACF Film. Furthermore if you are having any compression issues in Z Axis, feel free to check out our post here.

Perform z-axis calibration

• Click NEXT and wait for 1-2 minutes as the building plate extends to the LCD screen.
  
• Apply pressure and press down firmly on the sides of the building plate. Pull on the piece of paper to make sure the building plate is laying tight against it.
  
• Tighten all four screws on the sides of the building plate in a clockwise direction while pressing down on the building plate with the other hand, in a cross pattern order, e.g., top-right, lower-left, top-left, and lower-right.
  
• Tug on all four corners of the A4 paper to check for pressure intensity. If it is tight, please proceed onto the next step. If it isn’t, please perform the Z-axis calibration test again.

If the paper is still loose, please perform the Z-axis Calibration test directly on the resin vat. The FEP thickness is approximately 0.14-0.15 mm

Complete the calibration

• Click DONE on the touch panel.
• Wait for the building plate to retract. Once the plate has retracted, remove the A4 paper. 

After completing the aforementioned steps, the Z-axis calibration should be successfully done, and you are now prepared to embark on your printing journey.
