Klipper Firmware Flashing

This section explains the process of downloading the Klipper firmware file (klipper.bin) created in the Klipper Firmware Creation section from your Raspberry Pi, and installing it on your Anycubic Vyper printer using an SD card.

For the steps listed below, I will be using WinSCP as my FTP program of choice, you can use whatever FTP program you are used to, most of the steps should translate easily to other programs.

• Open WinSCP on your Windows computer and create a New Site;

WinSCP - New Site

• Enter the following information into the fields as described below

  • Host name: <IP address of your Raspberry Pi>;

  • User name: pi;

  • Password: <Your Raspberry Pi password>;

• Click Login;

WinSCP Settings

• You may receive a warning message advising 'Continue connecting to an unknown server and its host key to cache?';

  • Click Yes to continue;

Warning

• Navigate to the /home/pi/klipper/out folder;

  • Select the klipper.bin file;

  • Then select download;

klipper.bin

• Select the download folder of your choice;

  • Click Ok;

Download Location

• Navigate to the folder you downloaded the klipper.bin file;

  • Rename the file to main_board_20xxxxxx.bin;

Original

Renamed

• Copy the main_board_20xxxxxx.bin file to the root of an SD Card;

You will want to use a quality SD card (I don't trust the SD card that is included from Anycubic). You should format the SD Card as FAT32 and the main_board_20xxxxxx.binshould be the only file.

• Eject the SD Card from your computer properly;

• With your Anycubic Vyper 3D printer powered off;

  • Insert the SD Card with the main_board_20xxxxxx.bin file into your printer;

• Power on your printer;

  • The printer should make a few beeping sounds and the firmware will be installed;

The firmware update is a very short process, only takes approx. 10 seconds to complete. Leave the SD card and printer turned on for approx. 1 minute for good measure.

• Power off your printer;

• Remove the SD Card from the printer;

• Connect the Raspberry Pi via the USB cable to the printer;

• Power on the printer.
