Need Help Getting Klipper installed on a Kraken mcu Or MCU

I am essentially done building this thing. I have everything working. BTT Pi2 installed ok having all the expected software packages. I want Klipper to run on my Kraken for a lot of good reasons.

I am getting errors like Moonraker can not find comunicate with Klipper. Or cannot connect to MCU.

It is driving me nuts that this is holding me up right at the end of the build. I need the system at least booting into a workable configuration to I can make the adjustments I I am sure to have with my pinter.cfg file.

I cannot even find the buttons on the Kraken that BTT says are there.

Try these 3. https://docs.vorondesign.com/build/software/
BTT's config for the Kraken https://github.com/bigtreetech/BIGTREETECH-Kraken
And maybe use Kiauh https://github.com/dw-0/kiauh

I have successfully flashed everything onto my BTT-Pi2 but I cannot tell whats going on with the Kraken. How do you get into the blue grey menu screens? I have the Pi using the USB-c and the Kraken using USB standard. The board is powered by the power supply.

I am essentially getting and error that Klippy cannot connect to Klipper...any ideas?

Please share the actual, exact error.

(Also, blue/Grey menu screens? What?)

Thank you so much for the link! I am starting to upgrade to Kraken and need a sample .cfg file

Klipper is a 3d-printer firmware. Contribute to Klipper3d/klipper development by creating an account on GitHub.

This is the github for the config references. BTT published their generic config (that NoGuru posted above)

Klipper wants the printer.cfg.

Just copy the default kraken to your printer, rename the file to "printer.cfg" and start there.

You will need to add the MCU line. Should look like this:

[mcu]
canbus_uuid: ca90cdaf1bc3

or

[mcu]
serial: /dev/serial/by-id/usb-Klipper_stm32f042x6_050021000843565036343620-if00

And then you need to tell Klipper what type of printer it is with this:

[printer]
kinematics: corexy
max_velocity: 700 # 800 via ellis tuning for speed and acceleration
max_accel: 8000 # Set to 10000 for ADXL resonance testing
max_z_velocity: 300 # Max 15 for 12V TMC Drivers, can increase for 24V
max_z_accel: 400
square_corner_velocity: 5.0
