DO NOT UPDATE THE FIRMWARE BEFORE COMPLETING A FEW PRINTS.
If you update the firmware right away what are you going to say when asking for help after something doesn't work?
YOU: “I updated my firmware and my printer doesn't work.”
COMMUNITY: “Was it working before you updated the firmware?”
YOU: “I don't know, I didn't try.
Updating the firmware before using the printer introduces another variable to the troubleshooting session you may have to go through.
UPDATING THE FIRMWARE IS NOT SUPPORTED BY MONOPRICE

Note: If you have trouble updating, please format microSD card or use another microSD card and try again. Try a microSD card that is 4GB or less formatted with FAT. The printer can be picky at which cards it will update from so try a few cards.

1. Disconnect USB cable
2. Copy the lcd.bin file to the micro SD card and put into printer while powered off
3. Move the x-axis (x-carriage) all the way to the left making sure the endstop stays pressed in.
4. Slide the y-axis (bed) all the way to the back making sure the endstop stays pressed in.
5. Press and hold down the control dial/button
6. While keeping the control dial/button pressed down, power on the printer. Keep the control dial/button pressed down until the fan on the hotend starts spinning (about 3-5 seconds).
   The LCD will stay black until the update process is finished which is about one minute or less. The LCD will turn on when the update is complete.
7. Restart Printer
8. Delete lcd.bin from micro SD card if printer keeps restarting.

4. If microSD available and lcd.bin file exist. Turn on FAN to indicate updating has started.
5. Re-initialize IO and upload firmware for LCD module.
