[Sonic Mega 8K V2] How to Run the LCD Test

LCD is a critical component of resin-based 3D printers. The LCD screen is responsible for displaying the layers of the 3D model that will be printed. The light from the LCD screen passes through a bottom layer of a resin vat, curing the resin in a precise pattern that matches the 3D model's shape.

To ensure that the Sonic Mega 8K V2's LCD screen is working correctly, you can perform an LCD test. This test checks if the lighting and masking functions of the printer are working correctly. The following steps will guide you on how to run the test on your Sonic Mega 8K V2:

DO NOT look directly at the UV Light to prevent eye discomfort

1. LCD Test

Power up and Prepare

• Plug in the  power cable located at the back of the printer and switch on the power.

Perform the LCD  test

• On the touch panel, tap TOOLS > LCD TEST

• Click LIGHT UP mode or LCD GRID mode

Confirm proper functionality

• Compare the image on the LCD with the one on the touch panel.
• If the image shown on the LCD matches the one on the touch panel, it indicates that the LCD is functioning correctly. However, if there are any discrepancies, it may indicate that the UV lights or the Mono-LCD screen is not working correctly.

2. VAT Cleaning

Power up and Prepare

• Plug in the  power cable located at the back of the printer and switch on the power.

Perform the Vat cleaning

• Click TOOLS, then click VAT CLEANING.

Confirm proper functionality

• On the touch panel, a white rectangle will appear.
• On the LCD screen, a bright blue square will appear, while the entire screen is illuminated. Run this test to make sure the UV lights are distributed evenly.

3. Performing a Dry Print

If you're experiencing issues such as flickering or glitches, a dry print can be a helpful troubleshooting tool. A dry print is a test print that you run without placing the resin vat and building plate. This allows you to check whether the LCD is flickering or functioning correctly.

Power up and Prepare

• Plug the power source on the printer, and turn on your printer.
• Remove the resin vat and building plate from the printer.

Perform the dry run test

• Save a .CTB file onto a USB drive and then plug it into the USB port on your printer.
• Click on the file from the touch panel to start the print.

Confirm proper functionality

• Check the LCD screen to see if the image displayed on it matches the one on the touch panel.

Performing the above test can help you to identify any issues with the LCD and ensure that it is functioning correctly.
