I'm stuck at MCU Protocol error

I'm stuck at "MCU Protocol error" When the Pi comes up it goes to Klipper. I can't find how to get to just the Pi to run the commands there. Sorry, not a Pi person and this is driving me crazy.

What commands are you trying to run?

The question is how to get to the Pi shell. If I use the IP address it just goes straight to Klipper and I haven't found an option to close Klipper and just have the Pi OS screen. Though the machine is at work and I'm now home for the day. Probably should have built this thing at home and then moved it to work. I'm doing so much overtime that I barely get time on the build. 😕

What is a pi os screen? I think you're looking for the command line which you can use any terminal, I'd suggest powershell. Do a "ssh pi@ipaddress" (replacing IP address), default password is "raspberry"

I'll try that tomorrow. The ssh route goes straiht into the RatOS. I reflashed the Pi and now I'm at the printer screen. Maybe the SD card got corrupted? I'll chase through the rest of the initial install. Hope this has it fixed.

Sorry, the poor printer is well down on the current priority list. I re-imaged the Pi several times because I was having problems with the Pi using Wifi to get to the internet (likely just a problem with our internal network topology). Took the electronics home and skipped the Wifi part to force the Pi to use the router and that finally got everything talking and updating.
