unable to connect to MCU?
Ok.. i'm at a loss as to what happened and why. I have a Rat 500, all metal hotend and I printed 2 or 3 things yesterday, including mount for the BTT SFS V2.0. I hooked up the new SFS, plugged it in as shown in the document. All seem's good, the Dashboard showed the sensor and showed it had filament. I decided to check if I had any updates that were needed before starting a print...there were a couple so i applied them and now I can't get the pi to connect to the mcu, but yet, when i go to the http://ratos.local/configure?step=1 and in the upper right hand side and under Moonraker I choose flash all attached MCU's and it goes through and flashes and says successfuly flashed attached 1/1 mcu. I reboot and still the problem is there. Here is what log file is showing. Any help is greatly appreciated

Can you connect to the Linux is via ssh? Then you can do is - alg /dev/serial/by-id /*
This will give you all serial ports, then you can use the one that's most likely and out that in your config
