Thanks man! I got hung up at the point with the M112 error, and your video got me past it!

Just a clarification; `sudo apt update` simply updates the OS list of packages and compares to what is installed. Following up with `sudo apt upgrade` actually updates the pacakges/software. That just makes sure that things are up to date in terms of package versions etc so that when the Klipper script runs it is getting the right packages. It's not "grabbing information", it's actually downloading and installing the packages needed to compile Klipper for the SKR2.

Usually PA1 just means port A, pin 1. Arduino likes to label pins A & D for analog and digital but the chip also has ports A and ports D which don't correspond in any way to analog or digital. Given the SKR2 also uses pins PC & PE its safe to assume PA1 & PA2 is port A rather than A(nalog).

Seems the klipper process has changed, can you make an updated video for this board? please and thank you.

ok so finally I got everything working. there are some things that are a bit odd and different but. It worked it finally worked. Also took less time to figure this out than Marlin that firmware is absolutely incredibly ridiculous and excruciatingly painful to deal with.

To find what ARM chip you have on the skr 2, its printed right on the big chip in the center of the board. Newer models have the STM32F429.

Copying `klipper.bin` to the SKR2's SD Card can be done on the RPi. Just put the SD Card into the USB adapter as was shown in the video, but then plug into the RPi and mount the drive. Don't forget to rename the `klipper.bin` to `firmware.bin` as per the config file text. If you need help mounting the USB adapter on the RPi, google something like `mount usb raspberry pi` for help.

Would be really useful if you did a guide on proximity sensors / inductive sensors with the octopus board. Can't figure out how to check if mine is working or not using the 3 pin slot.

any idea why i'm follow you video and found that i can't home my printer due to all stopper show triggered but the actual printer is not ?

[zergmare]

I got mine to work! But I gotta ask, why use octoprint and not fluidd?

[FlashStationCom]

Thanks for the great tutorial! I'm stuck at 19:30, it's when you are puting your firmware.bin file in the boot. In your video, you have a one file FIRMWARE.CUR, while I have about 20 different files in my folder. Is it alright or did I do something wrong?

What happens it won't open on the command line when you add http, username and password for octopi

Hi Ed, first of all, thank you for this tutorial, im a big raspberry noob, you help me get into it.
Im having problems connecting to my skr 2 . if wont connect, it tries al the different baud rates but doesnt connect. i tried a different usb cable, i tried the different usb ports nothing.... can you help me?

Does the SKR 2 really need clipper I mean the processor is 32 bit clocked at 600+mhz.
I really can't see why a person should bother with klipper when the control board is so powerful.
The only Thing I can think of is only the interface

Great tutorial, you're level of detail is excellent and easy to understand. I have a question/issue though, I am using the SKR 2 Rev B board (identified by the MOSFET HY1904) .

Chose processor model STM32F429 in make menuconfig.
Edited config file in Octopi for
Used cp ~/klipper/config/ ~/printer.cfg

Your printer's firmware reported an error. Due to that OctoPrint will disconnect. Reported error: Can not update MCU 'mcu' config as it is shutdown

Here is the MCU setup in config:

[mcu]
serial:

Obtained from ls /dev/serial/by-id/*

Is there something obvious I am missing or is more information required? Thanks in advance.

Thanks for the tutorial! After about 8 trials, I'm desperate for some help... Perhaps you can see what's wrong?
