Print stops middle Air but the nozzle keep moving

OK. I figure out that this first issue is the same bed level/nozzle hitting the model as reported in various other posts here. I left my phone recording a new print and I was able to see the nozzle hitting the model and removing one of the legs from the bed. After that it create a mess just like this one.

Still haven’t found a solution, but going to try manual leveling the bed and tightening the screws as suggested in this topic
