[Sonic Mini] 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 Mini'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 Mini:

1. LCD test

Please avoid directly looking into the UV light to prevent any eye discomfront.

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

• A bright blue square will appear on the LCD. Compare the image on the LCD with the one on the touch panel.

 Confirm proper functionality

• Check if the image on the touch panel is same as the display on the LCD

2. Performing a Dry Print

If you're experiencing issues with 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 and
• Remove the resin vat and building plate from the printer

Perform the dry run test

• Save a sliced file onto a USB drive and then plug it into the USB port on your printer
• Click on the file from 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

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