In order to improve the quality of your models and produce high-quality 3D prints, Z-axis calibration is essential for every LCD 3D printer. Please refer to this video as an example. 

Here are the steps you need to follow to calibrate your resin 3D printer. 

Step 1: Remove the resin vat. Make sure to remove any objects present on the printer’s LCD screen.  

Step 2: Prepare a piece of A4 paper and lay it flat on the LCD screen. This piece of paper will be used for leveling the build platform. 

Step 3: Use a wrench to loosen all 4 screws present on the sides of the build platform. After loosening it, make sure to double-check to see if the platform is loose and movable. 

Step 4: Click on the Z-axis button on your printer’s LCD touch panel to begin the process. Wait for 1-2 minutes as the build platform extends to touch the A4 paper laying flat on the LCD screen.  

Step 5: Once the platform has touched down, press down tightly on the sides of the build platform and adjust it to make sure it is laying tight against the sheet of paper.

Step 6: Once the building platform has been adjusted, tighten all 4 screws on the sides of the build platform. 

Step 7: Click DONE on the LCD screen, and wait for the building platform to retract. 

Step 8: Once the platform has retracted, remove the A4 paper and you’re ready to begin your 3D printing journey!
