# Klipper Firmware Flashing

This section explains the process of downloading the Klipper firmware file (klipper.bin) created in the [Klipper Firmware Creation](/klipper-installation-for-anycubic-vyper/klipper-firmware/klipper-firmware-creation.md) section from your Raspberry Pi, and installing it on your Anycubic Vyper printer using an SD card.

{% hint style="info" %}
For the steps listed below, I will be using [WinSCP](https://sourceforge.net/projects/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.
{% endhint %}

* Open <mark style="color:red;">`WinSCP`</mark> on your Windows computer and create a <mark style="color:red;">`New Site`</mark>;

![WinSCP - New Site](/files/b2RH0bijgNAMHGsaI5oF)

* Enter the following information into the fields as described below
  * Host name: <mark style="color:red;">`<IP address of your Raspberry Pi>`</mark>;
  * User name: <mark style="color:red;">`pi`</mark>;
  * Password: <mark style="color:red;">`<Your Raspberry Pi password>`</mark>;
* Click <mark style="color:red;">`Login`</mark>;

![WinSCP Settings](/files/CXQDCsULkTeLNrfIeNRh)

* You may receive a warning message advising 'Continue connecting to an unknown server and its host key to cache?';
  * Click <mark style="color:red;">`Yes`</mark> to continue;

![Warning](/files/QJ1loDm0Qt3hgvag7mJr)

* Navigate to the <mark style="color:red;">`/home/pi/klipper/out`</mark> folder;
  * Select the <mark style="color:red;">`klipper.bin`</mark> file;
  * Then select <mark style="color:red;">`download`</mark>;

![klipper.bin](/files/0NEfwRE4r2ASdfr1NjAW)

* Select the download folder of your choice;
  * Click <mark style="color:red;">`Ok`</mark>;

![Download Location](/files/H7QccjK0MZGoyV2gLGuz)

* Navigate to the folder you downloaded the <mark style="color:red;">`klipper.bin`</mark> file;
  * Rename the file to <mark style="color:red;">`main_board_20xxxxxx.bin`</mark>;

![Original](/files/VPWunupNrRHauGRRvQrI) ![Renamed](/files/xm8U73xtCiPq1AcBBr15)

* Copy the <mark style="color:red;">`main_board_20xxxxxx.bin`</mark> file to the root of an SD Card;

{% hint style="info" %}
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 <mark style="color:red;">`main_board_20xxxxxx.bin`</mark>should be the only file.
{% endhint %}

* Eject the SD Card from your computer properly;
* With your Anycubic Vyper 3D printer powered off;
  * Insert the SD Card with the <mark style="color:red;">`main_board_20xxxxxx.bin`</mark> file into your printer;
* Power on your printer;
  * The printer should make a few beeping sounds and the firmware will be installed;

{% hint style="info" %}
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.
{% endhint %}

* 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.
