Filament Sensor failure
I built the CoreOne + kit and it tested fine and calibrated fine. I had maximum two prints with little success and then began having issues with the sensors. I changed the filaments and have not had one successful print since. I had to change the nozzle and take apart the nextruder, but now I still have sensor issues. I have taken it apart and followed the trouble shooting for the sensors, but nothing seems to work. No matter what I do I cannot get through to the sensor calibration, it immediately says there is a problem with the sensors. I am at a loss and frustrated.

Get on the chat with Prusa—their 24x8 support is one reason you paid the Prusa premium. They can walk you throught the process.
