[Sonic Mini 8K] How to Run the LCD Test

Before printing or when encountering an issue, you may need to check the status of your Sonic Mini 8K's LCD screen. This is to ensure that both the UV lights and the 7.1” Mono-LCD screen are functioning properly. We will guide you through the steps of performing an LCD test and how you can read the test. 

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

1. Running LCD Test

Power up and Prepare

• Remove the resin vat from the printer
• Plug in the power cable located at the back of the printer and switch on the power
• On the touch panel, click TOOLS → LCD TEST

Confirm proper functionality

• A white rectangular frame should appear on touch panel
• A blue rectangular frame will appear on the LCD
• Run this test to see if the image displayed on LCD matches the image on touch panel
• If you encounter any issues with the LCD, please refer here.

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.

Power up and Prepare

• 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

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

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

After making sure everything is functioning correctly on your LCD 3D printer, you’re all set to proceed to the next step: Z-Axis Calibration.
