First Ratrig Problems with connecting

Hello, I got my first Ratrig VCore3 and trying to connect klipper.

I followed all instructions and doublechecked the wiring. Everything seems to be fine. Also the firmware upgrade was succesfull.

Now i am trying to set the printer.cfg. But i am not able to connect the printer. Also no light is blinking or something on the BigTreetech Octopus V1.1 Mainboard.

I attached my klipper.log

Hope someone can help me. I am getting crazy xD

In the log i can see this error
File "/home/pi/klippy-env/lib/python3.9/site-packages/serial/serialposix.py", line 265, in open
self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/btt-octopus-11'
Dont know if this need to be fixed before the cfg and how

Looks like firmware wasn't flashed, how did you verify it was flashed successfully?

Hm i didnt checked it. Didnt know how. Just followed the instructions on ratos. And updated all packsges. I see this was only for the pi packages. Do you know a tutorial how i can updste the board?

I copied the img to the pi connect the board with the cable. Set the jumper into the board and started the updates on the pi

Ahh, you missed the step where you flash the firmware then

Thanks for your respond. I am little bit confused now. I have done this step. Connected the board to the pi after installing ratos on the pi. Can xou plz tell me how i can check the firmware on the board or where i can get the firmware for the board so i can try i it mannually again

did you do this step ?

After completing the wifi setup wizard, wait a couple of minutes, then open http://RatOS.local/configure?step=1 in your browser (or whatever hostname you chose during setup). Complete the wizard to flash your control board and optionally a toolboard.

Yes sir i did. Something funny happend
I put the jumper back for the firmwareupdate and the printer started.
The blue one

I thought this is only for the update and not needed for working like in the description

Upload a picture of your wiring

progressive-amaranthOP•7/3/23, 3:52 AM

Here is a picture of the wiring. I didnt cleaned up the wiring. Need to debug first. Dont know if you can see something.

blacksmithforlife•7/3/23, 4:42 AM

Yeah, can't see anything from that angle and the fact you used red and black for everything. Time to get out the multimeter and test everything

progressive-amaranthOP•7/3/23, 5:04 AM

The multimeter showed 0V. I will check it seperatly if it works.

progressive-amaranthOP•7/3/23, 5:04 AM

Thanks for your help

I checked the wiring and it was wrong so i changed it but i got a short circuit on the board. Now i will get a new one. The Converter wasnt on 24V. After the short circuit i measuered with the multimeter and found out that the converter had 27V. I changed now to 24V and will try it again with the new board.

progressive-amaranthOP•7/4/23, 4:11 AM

Can you give me an advice so this doesnt happen again. Can i first connect the board to the converter and try it. Is this the only way the bosrd can get a short circuit. Or are the also other ways i need to check.
