I have had a problem with my new longer lk4 pro. I started a new project of printing that lasted 6 hours, but during the job I had to go out for 1 hour. When I came home the printer was as blocked without the job's finished even if it wasn't off. I read in the display "The job is not done. Do yo want to recovery the printing?" and I chose "yes". But the printer started to whistle and it turned off suddenly. I don't understand why and I need an help from you. What is my printer's problem? How can I do? What can be the solution? The only thing that I've noticed is that nozzle is wasted as we can see in the photos. I look forward to your answer!! Thank you.
