Afterburner Toolhead PCB (rev3.2)

Sourcing Parts

I purchased the PCB only, I sourced the rest of the parts for the kit myself.

Kit contains the Quantity needed for building 1 unit.

Klipper Firmware Configuration

USB

cd ~/klipper/
make clean
make menuconfig KCONFIG_CONFIG=config.easy_brd

Set the following configuration:

(Top)Klipper Firmware Configuration[ ] Enable extra low-level configuration options    Micro-controller Architecture (SAMC21/SAMD21/SAMD51/SAME5x)  --->    Processor model (SAMD21G18)  --->     Bootloader offset (8KiB bootloader)  --->    Clock Reference (Internal clock)  --->    Communication interface (USB)  --->  [Space/Enter] Toggle/enter [?] Help [/] Search[Q] Quit (prompts for save) [ESC] Leave menu

Backup config, Build and Flash to the board:

cp config.easy_brd ../printer_data/config/Firmware/
make KCONFIG_CONFIG=config.easy_brd -j4
sudo apt install bossa-cli
sudo bossac -i -d -p /dev/ttyACM0 -e -w -v -R --offset=0x2000 out/klipper.bin

Klipper Expander

PCB to expand the ports that can be used for fans and neopixels. I already have RGB neopixel strips and will need an additional neopixel header as the Stealthburner LEDs I have purchased are incompatible with the strips as they are RGBW.

Printing Parts

There are three different mounts, one vertical, one horizontal and one for DIN rail.

I have printed the horizontal mount as I am planning on mounting the Klipper Expander on the bottom of the rear electronics compartment of the Voron 1.8.

Assembly

I purchased this already assembled.

Klipper Firmware Configuration

USB

cd ~/klipper/
make clean
make menuconfig KCONFIG_CONFIG=config.klipper_expander

Set the following configuration:

(Top)Klipper Firmware Configuration[*] Enable extra low-level configuration options    Micro-controller Architecture (STMicroelectronics STM32)  --->    Processor model (STM32F042)  --->     Bootloader offset (No bootloader)  --->    Clock Reference (Internal clock)  --->    Communication interface (USB (on PA9/PA10))  --->    USB ids  --->    Optional features (to reduce code size)  --->[*] Optimize stepper code for 'step on both edges'() GPIO pins to set at micro-controller startup  [Space/Enter] Toggle/enter [?] Help [/] Search[Q] Quit (prompts for save) [ESC] Leave menu

As the firmware is too large to fit in the supplied flash, we also need to disable some features:

(Top) → Optional features (to reduce code size)Klipper Firmware Configuration[*] Support micro-controller based ADC (analog to digital) [*] Support communicating with external chips via SPI bus[*]     Support software based SPI "bit-banging"[*] Support communicating with external chips via I2C bus[*]     Support software based I2C "bit-banging"[*] Support GPIO based button reading[ ] Support Trinamic stepper motor driver UART communication[*] Support 'neopixel' type LED control[*] Support measuring fan tachometer GPIO pins    *** LCD chips ***[*] Support ST7920 LCD display[*] Support HD44780 LCD display    *** Accelerometer chips ***[*] Support adxl accelerometers[*] Support lis2dw and lis3dh 3-axis accelerometers[*] Support MPU accelerometers[*] Support ICM20948 accelerometer    *** External ADC type chips ***[*] Support thermocouple MAX sensors[*] Support HX711 and HX717 ADC chips[*] Support ADS 1220 ADC chip    *** Other external sensor chips ***[ ] Support ldc1612 eddy current sensor[ ] Support angle sensors  [Space/Enter] Toggle/enter [?] Help [/] Search[Q] Quit (prompts for save) [ESC] Leave menu

Install the boot jumper and reset the board to put the board into DFU mode.

Backup config, Build and Flash to the board:

cp config.klipper_expander ../printer_data/config/Firmware/
make KCONFIG_CONFIG=config.klipper_expander -j4
make KCONFIG_CONFIG=config.klipper_expander flash FLASH_DEVICE=0483:df11
