LCD Screen Firmware Update
- Copy the “LCD.BIN” files to the SD card. (Select the “LCD.BIN” file in the “Print” interface is NOT NEEDED when updating the LCD Firmware.)
- Turn off the printer and reset the X-axis and Y-axis. Move the X-axis and Y-axis to make sure the limit switches are triggered.
- Press and hold the knob to turn on the printer.
- Keep pressing the knob until the two extruder fans start to work and the LCD firmware will then start automatically.
- The update process takes about 4 minutes. After the update is completed, the screen will automatically restart. The screen is updated now.
- After the update is complete, please delete the firmware in the SD card in case the update will start automatically when you turn on the printer.
