+#### Klipper.bin And Printer.cfg

+**Compiling The Klipper.bin File**  
+Referring to the notes in the example printer.cfg file MKS offers, you have to choose the following settings for compiling the `klipper.bin` file:

+
+After you compiled the bin file, you need to *rename the file to `Robin_nano_v3.bin`, copy it onto a microSD card (FAT32 formatted, completely empty) and insert it into the microSD cardreader while board is *not* powered on. Then power on the board and wait about 5-10min to complete the flashing procedure. Turn off the power again, take out the card and connect the board to your Klipper host via USB cable.
