As the title says, there is a potential major issue in the logic of printer starting up after factory reset. The bed is at the top part of the chamber, I decided to do factory reset since some prints started doing problems. OK, factory reset, printer restarts, welcome screen next next, and then self test. The bed goes up, and it presses on the nozzle with such force that you can see the rods and siderails bending a bit, and nozzle is now possibly bent. I will wait for self test to finish and inspect the nozzle. That tells me that the sensor in the bed are not working after you press selft test, the bed just goes up, and when it touches the nozzle it does not stop but continues to push up and bends the whole structure, and only then stops, probably from over current in the motors. This should NOT happen!!!
I think for that it would be best to create a ticket with appended log, so Bambu can understand how that happened.
will do 
Just have to pull the logs
