Performing Z-axis Calibration on the Sonic Mighty 4K

February 22, 2021 Uncategorized 0

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

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

Step 1: Settings

On the touch panel, click TOOLS, then click Z CALIB on your touch panel to begin the calibration process.

Before clicking NEXT, please complete steps 2 – 4

Step 2: Remove the Resin Vat

Remove the resin vat and make sure to remove any objects present on the machine’s platform. 

Step 3: Install the Build Platform

Attach the build platform knob to the printer and make sure it is aligned with the platform at the back. Screw and tighten the build platform. 

Step 4: Loosen the Screws

Use the Allen wrench included in the toolbox to loosen all 4 screws on the sides of the build platform in a counterclockwise direction. After loosening it, double-check to see if the plate is loose and movable.

*Note: While loosening the build platform, DO NOT remove the 4 screws present on the sides.

Step 5: Place a piece of paper on the LCD

Prepare a piece of A4 paper (roughly 0.07-0.10 mm) and lay it flat on the LCD screen. This piece of paper will be used for leveling the build platform. Click NEXT and wait for 1-2 minutes as the build platform extends to the LCD screen.

*Note: Make sure the A4 paper is large enough to cover the entire LCD screen.

Step 6: Apply pressure on the Build Platform

Once the build platform has touched down, apply pressure and press down firmly on the sides of the build platform. Pull on the piece of paper to make sure the build platform is laying tight against it. 

*Note: Make sure your device makes a beeping sound before moving onto the next step. 

Step 7: Tighten the Screws in a Cross Pattern Order

Once you have successfully adjusted the build platform, tighten all four screws on the sides of the build platform in a clockwise direction while pressing down on the build platform with the other hand, in a cross pattern order, e.g., top-right, lower-left, top-left, and lower-right. 

Step 8: Double-Check Z-axis Calibration

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. 

Step 9: DONE

Click DONE on the touch panel and wait for the build platform to retract. Once the plate has retracted, remove the A4 paper.
