The entire cone of the nozzle is below the top edge of the bed. I did another print (w. a raft) of a cube and it repeated again the banging against the bed.
I checked the screws and all are tight. I did remove the print module to fix a filament problem but it is installed per the instructions with one empty hole in the plate above the screw and one empty below the bottom screw. But this is moot as the printer after installing the print module printed once fine.
Attached is a picture of the print head as it was stoped. I just turned off the power to the printer. Thanks for the help.
