The LCD orientation for this firmware is set to landscape (horizontal) mode due to how Marlin works. The stock LCD is in portrait (vertical) mode.

You should print off the LCD rotation adapter if you want to use the LCD easier. All the STL files are in the package below. Source: Thingiverse

1.i – In the file explorer open the mks_robin_nano35_kp3s folder

1.j – Look for the latest Robin_nano.bin file and copy that to your SD card. This SD card must be FAT32 formatted.

1.k – Power OFF your printer and Insert the SD card with the latest Robin_nano.bin file into your printer. Turn the printer on. It will take a little longer than normal to boot up.

1.l – When the printer boots you will see the TH3D logo on your LCD. Make sure to reset your EEPROM on your printer after flashing any firmware. You can do this from your printer LCD or by sending a M502 followed by M500 with your favorite Gcode sender application.
