Raspberry and mother board crashed
Today I was printing a calibration print, nothing special and I wanted to check how far along the print was and I couldn't connect to ratos through the web interface. When I checked the printer, the calibration print finished, raspberry pi and everything had power so there should be no reason for me not to be able to connect to it. So after a while I saw that ratos was hosting a wifi access point, just like at the beginning where you flash your motherboard and initialize your printer. So now I had to reinstall the ratos image to raspberry pi and now I am attempting to reflash the motherboard. Why would this happen? I grounded everything. The raspberry pi has it's own power source.

it just lost connection to your wifi - no need to reinstall ratos. You probably need to move it closer to the router and get a better/newer router
I have put an access point right next to the raspberry pi and it didn't want to connect, I also later just plugged and ethernet cable directly into the pi and nothing
I have seen where the camera can try and stream too much and it crashes the networking until you reboot the pi
I don't have a camera connected. The weird thing is, OK I reintalled ratos but now I just cannot flash the motherboard. It says that the motherboard is unresponsive.
Shouldn't need to reflash the MCU. If you can SSH into the pi, you can check under
/dev for the MCU device link.I don't understand. When I try connect my pi with the motherboard and turn everything on, it says "moonraker can't connect to klipper". So I go under the configure steps and try to follow the steps again, but now I am stuck with the board flashing step. Could you please tell me the steps and what to look for under the /dev?
If you do an
ls -l /dev the MCU should be pretty obvious if it's being seen.
Given that you've released the pi, it's likely that the settings in printer.cfg for the MCU device are missingis this it?
Yes
Now that needs to be in your printer.cfg
The first image shows what is inside the printer.cfg file, now if I go to the directory i see in the printer.cfg ->
You might be able to go through the setup and skip the firmware flashing. I don't know for sure, never tried it. But at this point your MCU board is already flashed. You just need the printer.cfg fully configured. If you have a backup that could work.
Okay i fixed the problem. The thing was quite unfortunate. When I decided to reinstall ratos we somehow didn't have internet access that's why the c_helper function was missing. (I checked the
system status klipper.service and there was an error with the c_helper.os). So now I checked that I had internet access and reinstalled everything so now it works. Thanks for the help.If you don't mind, mark as resolved.
