Octopus V1.1 detected but is unresponsive
I am currently setting up a ratrig vcore 3.1 and am struggling with the firmware setup.
I have connected the raspberry to the btt octopus v1.1 as described in the instructions.
After inserting the microSD card, I was able to start the configuration via 'http://ratos.local/configure'.
After selecting the control board and flashing the firmware via microSD card, the following message appears:
"
Octopus V1.1 detected but is unresponsive.
Klipper doesn't seem to be running on your board, which may indicate faulty firmware or a faulty board. Please check your board and try flashing it again.
"
Flashing the firmware seems to have worked, as the SD card now contains a .CUR file instead of a .bin file.
dmesg gives the following output:
"
[ 5602.331123] usb 1-1.3: new full-speed USB device number 7 using xhci_hcd
[ 5602.442537] usb 1-1.3: New USB device found, idVendor=1d50, idProduct=614e, bcdDevice= 1.00

"
and ls /dev/serial/by-id returns
"
usb-Klipper_stm32f446xx_btt-octopus-11-if00
"
Does anyone have an idea what the problem could be?
I already tried:
- a different microSD card
- everything is unplugged except 24V power, 5V power for the raspberry pi and USB connection between the pi and the octopus
- flashing the octopus with 5V USB power

"I've seen this happen if klipper is restarted before it has finished compling it's files. If you reflash and connect to the wifi, try waiting a good 5-10 minutes before going through the board verification process and see if that fixes the issue. I'm looking at ways to prevent this from happening, it's getting quite annoying!

I tried doing exactly what you suggested, but the issue is still coming up for me. Do you have any more suggestions?
Skip the board screen entirely (i might've just replied to you on reddit)
To fix it you can do:

That seems to have worked! Thank you!
I was also wondering if there was an easy way to change the wifi for the printer if it moves locations?
Yeah just go to the configure page. If the pi can't connect to the configured wifi network it'll host the RatOS hotspot and you can just connect to that and go to /configure. In fact /configure is always available, change it as much as you want 🙂

This helps so much and I really appreciate it, but I think I have one more question. I was trying to connect to an open network and every time I try to do so it does not allow me to connect, is there any way to fix this or will it only work for password protected networks?
It will only work on password protected networks because you shouldn't be using unprotected networks (!!)
that's a major security risk
You're allowing everyone and their mom to start a fire where your printer is located.
Unprotected wifi is just a bad idea in general

Okay, I will have to talk to IT at my work and get the printer connected to the secure network. I was hoping to be able to just connect it to the guest network, but that is okay
If you talk to them i'm sure they'll tell you not to connect it to the guest network anyway 😄 You can just use the hotspot at work 🙂

Oh I did not know the hotspot would work for printing things as well, this is good to know
It will indeed, Fabreeko has used it at rep rap festival for that purpose actually

Well this is great news! Thank you so much for all of your help!
Sure thing!
