RatOS will not connect to my mcu
Have tried different cords, when I flashed the controller it returned a .cur file like it should have, now though I cannot connect to it.

Have you looked at and worked through all the suggestions in https://discord.com/channels/582187371529764864/1046952693480038500 ?

Are you using RatOS? I had the same problem after updaten my SKR2. Search for the Serial ID and check if that’s correct in the config

Ive worked through all the suggestions and it seems like the octopus is being recognized by the pi but I think the serial id for the board may be incorrect in config
did you flash it with the correct firmware?
national-gold•2y ago
Yes, I’ve tried the one from the firmware_binaries folder and the generic klipper one for the octopus, the klipper one shows up on ssh but with the one from ratos it doesn’t show up

@jeffbezosvevo I'm at exactly the same point- worked through everything in the FAQ linked, checked that the .bin changed to .cur, firmware is correct for the SKR2 board, checked all wiring

It just doesn’t show up or connect and I’m not really sure what else to try

Me either, mine is a V-Minion but I'm in the same spot.
Did you first run
COMPILE FIRMWARE
?national-gold•2y ago
Yes
Is there any way to recompile without starting over with ratos?
Yes, run the macro in the web UI

I recompiled and reflashed my board, no change.
and what is the output when you run
dmesg -w
and then plug in your octopus?sensitive-blue•2y ago
Mine just returns the same 'mcu unable to connect' message, that's before and after plugging in the USB to the SKR2.
