I can't get anything from my printer since I change filament (I always use PLA from SUNLU). I changed the nozzle, redo the leveling... Every time now, the nozzle seems way to close to the bed and the PLA just stick to the nozzle and not the bed. I was wandering if I need to change the hot end.
This is me leveling each corner and center of the printer using a flyer from a shoe store.
and this is the result when I try to print stuff (actually square to refine the leveling):
