Failed Z axis calibration after mk4s -> Core One upgrade
What sort of things should I look into for troubleshooting why the Z axis fails calibration? It seems to make a grinding sound. It is able to move the bed up to the top.

Check if the nozzle is actually hitting the build plate. I had to lower the nozzle a bit to pass the Z axis calibration.

Yes, that was the problem.

Going to piggyback on here as I am having the same issues and tried to lower the nozzle but no luck. I have tried adjusting the trapezoidal nuts and even have a level to check the true of the bed and everything looks good but just will not pass. Any ideas on what else it could be?
