Updating the LCD Firmware

1. Get a microSD card and format it to FAT-32 with 4096 bytes for the sector size
2. Copy the contents of the LCDFirmware directory to the root of the SD card. (Note: This needs to be just the contents of the folder. Do not copy the LCDFirmware folder itself)
3. Turn off your printer if it is on
4. Remove the front panel of your printer by removing all the bolts on the face of it. This does include the ones holding the Y bed rods in place
5. Gently pull the panel forward so you can get to the side of the LCD screen. On the left side of it there is an SD card slot that you should have access to via a cutout in the box around it. If you do not, just remove the box around the screen by removing the 4 bolts that hold it on

12. Restart your printer and you should see a new boot animation
