This project is a modification of the Ender 3 V2, replacing the original print head with a Voron Afterburner. All the parts needed for this modification are listed in BOM. The part of the mod is changing the firmware to Klipper instead of Marlin, which is optional and can be done separately.

It is recommended to print the hotend assembly parts with temperature-resistant materials such as PETG or ABS. Voron design team recommends using primary and accent color (for more information, check out their docs). They recommend printing the parts with 40% infill and 4 outer walls.
Detailed assembly instructions coming soon..
Installing Fluidd, the Klipper WebUI, is fairly straightforward:
Download the Raspberry Pi image here or clone the repository onto an existing OS. After downloading, flash the image to a SD card. Insert the card into the Raspberry Pi, and you're set to go.
There are instances of running Fluidd and Klipper in Docker, so you could also try that.
To install Klipper:
```
cd klipper/
make menuconfig
```
This step is for SKR Mini E3 V2
- Select "Enable extra-low level configuration"
- STM32F1
- STM32F103
- Bootloader Offset: 28KiB bootloader
- USB for communication
- Enter the USB ID. You can find them by
lsusb -v. Vendor ID should be0x1eaf, USB Device ID should be0x0004and USB Serial Number is the "iSerial" from lsusb -v, so 0. - Put !PA14 into the GPIO Pins
- Save the config
Then compile the firmware:
make clean #use when updating firmware!
make
When compiled, copy and rename the klipper.bin file in /klipper/out/ folder to firmware.bin (check your board for naming convention) and copy it to an SD card. Turn off the printer and insert the card. Turn on the printer. The firmware should be flashed.
Then find the USB ID:
ls /dev/serial/by-id/*
Change the serial in printer.cfg:
[mcu]
serial: /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0
Since I've got a BTT SKR Mini E3 V2 board, I copied the configuration I found for this board and modified it to suit my printer. The configuration file is attached and there are marks where any additional changes are required.
Copy the printer.cfg to klipper_config/.
