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.
Hello
How are you?
The prompt "Whether to resume printing" is the printer's power-off and resuming printing function. This situation means that the MCU restarts while you are away.
When you warm up the hot end, the screen turns off, which means that the motherboard has lost power, and you can notice that the 3010 fan of the hot end is not working.
I will first confirm the root of the problem with you, and then provide you with a solution.
