[Sonic Mini 8K S] 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 8K S'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 8K S.

DO NOT look directly at the UV light to prevent eye discomfort.

1. Running 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

Confirm proper functionality

• The rectangular image should appear on the touch panel and LCD screen
• Run this test to see if the image displayed on LCD matches the image on touch panel

2. 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.

• Plug in the power cord and turn on the printer 
• 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
