How to Install Klipper on Sidewinder X2: Config and Setup

The Sidewinder X2 is quite a capable machine, but it can be even better with Klipper Firmware. In this guide I will show you how to install Klipper on Sidewinder X2 and take advantage of all the benefits it comes with.

What is Klipper?

Klipper is an open-source firmware for your 3D printer that combines the power of a Raspberry Pi and your printer main board for better printer control. By doing this, you are able to run your printer at higher speeds with better precision and control.

Why Install Klipper on Sidewinder X2?

By installing Klipper on the Sidewinder X2, you will be able to print a bit faster compared to a stock printer, and you will also be able to control your printer remotely, trough Wi-Fi. The main reason to install Klipper is to use Pressure Advance and Input Shaper, which will greatly improve your print quality and speed.

To install Klipper on Sidewinder X2, you need to have the following:

  1. Raspberry Pi (any Pi version will work)
  2. MainsailOS or FluiddPi – In this guide I will use MainsailOS and a Raspberry Pi 4.
  3. Sidewinder X2 3D Printer
  4. Quality Power Supply for your Raspberry Pi

Before you begin

Before you begin

Please note that installing Klipper on the Sidewinder X2 requires some experience with 3D printers and hardware. This is not a trivial task for beginners, and you may break your printer during the process. If you don’t feel comfortable doing this, then keep the stock firmware.

Read the full guide carefully and install Klipper on Sidewinder X2 only after you properly understood all the steps involved. If you have questions before starting, leave a comment and wait for a reply.

I am not responsible for any damage you may cause to your printer by following this guide. You are doing this on your own responsibility.

The configuration file shared in this article, is made for the stock Sidewinder X2. It’s also worth noting that the stock touchscreen will not work anymore, and you will need to use the WebUI for controlling the printer. If you still want a standalone touchscreen, then I recommend buying a BIQU PI TFT50 and install KlipperScreen.

Install Mainsail or Fluidd


Before we begin, we need to install the web interface for our Klipper setup. I recommend installing Mainsail because it is actively developed and it’s easy to use, but you can also install Fluidd.

I have written complete instructions on how to install Mainsail OS and Fluidd, so check out one of those articles before moving to the next step. In this guide I will use Mainsail.

The articles also cover the installation of KIAUH which is a handy tool to have when running Klipper.

Now you are in the SSH console of your FluiddPi install. Enter the Klipper folder:

cd klipper

Open the Klipper Firmware Configuration screen using the following command:

make menuconfig

The Klipper Firmware Configuration screen will appear. Using your navigation keys, move through the menus and replicate the same settings I used.

When finished, press Q then Y to save your configuration. Now run the following command to start building the firmware:


The build process will start and when finished, the firmware will be ready to install.

Put the printer in DFU mode

The Ruby 1.2 board used by the newer Artillery printers need to be put into DFU mode in order to flash the firmware. This is done using the M997 command from a terminal window. I like to use Pronterface, but you can do it via OctoPrint or any other terminal of choice.

Connect your printer to to the computer via a USB Cable, and check the COM port in Device Manager. In my case, it’s COM3

Open Pronterface, and connect to the printer using the COM port and the 115200 Baud Rate, run the M997 command then proceed to the flashing step.

If this command fails, then you need to put the machine in DFU mode using the jumper pin on the board.

To do this, you need to remove the bottom cover of the printer in order to gain physical access to the Artillery Ruby board. Then, you need to install a jumper to connect the BOOT and the +3.3V pin. This connection will put the Ruby board in DFU mode and will allow you to flash the printer.

When the flashing process is complete, the jumper can be removed.

Flash Klipper firmware on Sidewinder X2

Back to the Pi terminal window, connect the USB cable from the X2 to the Pi and enter the following command to list all the USB devices:


A list of USB devices will be returned. Our printer will be listed under STMicroelectronics STM Device in DFU Mode. We need to know the ID of the USB device.

Start the flashing process with the following command:

make flash FLASH_DEVICE=0483:df11

The flashing process will start and in a few seconds, it will be completed.

Copy the printer.cfg file to Mainsail

To make things easier, I pre-configured a printer.cfg for the stock Sidewinder X2 which can be downloaded and copied in Mainsail.

Navigate to Machine, then click on the Upload button.

Mainsail Upload cfg | How to Install Klipper on Sidewinder X2: Config and Setup

Select the printer.cfg file to upload it, then use the power button in the top right corner to perform a restart. If everything is configured correctly, the printer will be connected. If this doesn’t happen, then you probably need to update the serial port in the config file. KIAUH can help with that.

Feel free to home the printer first, to make sure everything is running correctly. Heat up the nozzle and heatbed and check if the temperature rises as expected. If everything looks good, then you are ready to start the calibration of your Z offset.

Please note that my config includes the calibrated values for my stock Sidewinder X2. These settings should work pretty well, but I recommend taking the time and doing your own calibrations for best results.

I also recommend using a small piece of tape to cover the 5V pin coming from your Raspberry Pi. This will fix the always on display from the printer.

If you want to improve the probing speed of your Sidewinder X2, I also recommend checking out this macro. It speeds up probing quite a lot, and it’s easy to setup.

How to revert to stock firmware on Sidewinder X2?

The flashing process for the stock Marlin firmware on Sidewinder X2 was described by Artillery in this PDF file, so I won’t go trough the whole setup again.

First, you need to download the latest stock firmware source and compile it. Then, you put the Ruby Board in DFU mode like shown previously, using the jumper pin. Finally, you flash the firmware using the tools mentioned in Artillery’s PDF.

I might do a more detailed guide in the future, if this proves to be an issue for people trying to revert to stock.

Wrapping up

I hope this guide was helpful for you, and now you are running Klipper on your Sidewinder X2. The printer running Marlin is fine, but with Klipper the machine can be really good.

After you do some prints with the X2 running Klipper, you will probably see that one of the main limiting factors when printing fast is part cooling. I covered the most popular hardware upgrades for the X2 in the Artillery Sidewinder X2 Upgrades: Paid and Free article. Check it out, you might find something useful there.

  1. I have been transferring my Genius Pro to Klipper just now. Initially it didnt work, but I got a great hint from someone in Reddit, saying I should issue the ls /dev/serial/by-id/* command after having flashed the firmware and connected the printer with the PI, to find my own ID which had to be inserted in the MCU part of the printer.cfg file (this in case you are using a printer.cfg from soomeone else.)
    MAy be some other read here might benefit from this as well.
    Thanks for the general isntructions in any case

  2. Hi. Is there a way to enable the runout sensor? I checked the documentation and there is a switch/config but I have no clue what pin I have to add.

  3. If I remember correctly, the filament sensor on the X2 is wired to the TFT screen.
    If you change its location, then you should be able to find the pin and enable it in the config.

  1. First of all thank you for the detailed tutorial.
    Unfortunately, I had to take the jumper variant, but it works!

    I have two questions.
    With the heightmap I get a print bed difference of 0.13mm. Is this ok?

    With some prints I get the following error message: error: Move out of range: -22.000 85.000 5.000 [0.000]

    I use your config file. Do you know what could be the reason?

  2. hi i am getting this when i try to flash the ruby board
    File downloaded successfully
    Transitioning to dfuMANIFEST state
    dfu-util: can’t detach
    Resetting USB to switch back to runtime mode

    1. Had the same issue, rebooting the raspberry pi running mainsailos too after flashing and removing the jumper solved the issue…

  3. Hi. It would be nice adding the following to your printer.cfg in order to have some control about the LED.

    [neopixel my_neopixel]
    pin: PB7

    [gcode_macro LED_ON]
    SET_LED LED=my_neopixel RED=0.5 GREEN=0.5 BLUE=0.5

    [gcode_macro LED_OFF]
    SET_LED LED=my_neopixel RED=0 GREEN=0 BLUE=0

          1. Option ‘set_led led’ is not valid in section ‘gcode_macro led_on’

            Once the underlying issue is corrected, use the “RESTART”
            command to reload the config and restart the host software.
            Printer is halted

    1. Hey, i tried the neopixel macro along with some others with output_pin.
      It seems that klipper in not a fan of it.

  4. Hello4

    Thank you very much for this perfect description.
    I have a few questions about that.
    1, How to turn on the filament sensor,
    2, Pressre Advance and Imput Sharper functions how to set,


    1. 1. The filament sensor would bees to be connected to the board and configured.
      2. I included the settings in the config. But if you want to tune them, follow the Klipper documentation

  5. Hi.
    Thank you for the article. I have done this, but I always get the Message, that klippy can not be connected.

    I have also looked, what the right USB-Port-Adress is, but I don not get a connection.

    Who can help me?

  6. hello, thank you for this tuto ! To install it on a genius pro I only need to change “position_max” values for all 3 axis since its the same hardware ?

  7. Hi, it would be nice for your preconfigured printer.cfg that you add the line:

    [controller_fan stepper_fan]
    pin: PC6
    idle_timeout: 300

    This will enable the fan at the bottom to kinda cool the stepper driver. Without there will be missing steps while printing, reason being due overheating.
