Configuration and Documentation for the Annex K3

Installation

Install some headless RPi OS, then use KIAUH to install klipper, moonraker, fluidd, and pgcode.

Flashing the Z-Axis Controller (BTT-SKR 1.4 Turbo)

You can do the configuration step automatically with:

cp ~/printer_data/config/klipper-make/bttskr14.config ~/klipper/.config

Run make menuconfig from the klipper directory, and pick the following options:

1. Architecture: LPC176x
2. Processor: lpc1769 (120MHz)
3. Bootloader: 16KiB
4. Interface: USB

Note: If make menuconfig fails because of a set locale error, run this command to fix it: export LC_ALL=en_GB.UTF-8

Then run make to build the firmware. Grab that from the printer with scp vandal:klipper/out/klipper.bin firmware.bin, and then copy it onto the microSD card. Hit the reset button to flash the firmware. The firmware ID should be:

/dev/serial/by-id/usb-Klipper_lpc1769_0A60FF0D22813AAFF5116A5CC12000F5-if00

Flashing the XY-Axis Controller (Constellation Supernova)

You can do the configuration step automatically with:

cp ~/printer_data/config/klipper-make/supernova.config ~/klipper/.config

Run make menuconfig from the klipper directory, and pick the following options:

1. Architecture: RP2040
2. Bootloader: 0
3. Interface: USB

Then run make to build the firmware. Grab that from the printer with scp vandal:klipper/out/klipper.uf2 klipper.uf2, connect the RP2040 to the computer via a USB B Micro cable while holding down the boot button, and then copy it onto the device. Connect the device back to the Raspberry Pi. The firmware ID should be:

/dev/serial/by-id/usb-Klipper_rp2040_E6609103C3335822-if00

Flashing the Extruder Controller (EBB 36)

You can do the configuration step automatically with:

cp ~/printer_data/config/klipper-make/ebb36.config ~/klipper/.config

Run make menuconfig from the klipper directory, and pick the following options:

1. Enable extra low-level configuration options
2. Architecture: STM32
3. Processor: STM32F072
4. Bootloader offset: 8KiB
5. Communication interface: CAN bus (on PB8/PB9)
6. GPIO Pins: !PB10

Then run make to build the firmware. Flash using python3 ~/klipper/lib/canboot/flash_can.py -u 9e75a34aab5b.

TODO

• Check interop between fluidd and pgcode.
