I did a 7 hour print successfully. After that I started a new print immediately. First everything was ok, but after a while nozzle didn't extrude material properly. I stopped the printing. After that print core aa didn't cool down (it stayed 175c and just said "waiting"). So i booted the printer. I unloaded material 1(pla) and loaded the same material back. In loading The material came out from the nozzle end (maybe little bit thin). After confirming the loading of the material printer started to cool down the print core aa. It was again stuck for maybe 15minutes and didn't cool down (said "waiting" in the printer). I booted the printer again and waited for the cores to cool down to 40c. After that I tried to start printing and cura was stuck in preparing phase for a half hour and it didn't start printing. The temperature of the core aa was around 210c all the time. II had not other option the to boot the printer again. Is there a problem with the cooling or why is it just stuck in preparing phase?

    It sounds like your front fan may not be running; if strings of filament have gotten caught in the fan blades, the fan won't run. If it's not running, the print won't start, but it also won't be able to finish cooling down the print core after you try to abort it.

    Power of the printer and use tweezers to try to remove any visible strings of filament around the fan. When the fan is clear of debris strings it should run normally again.

    It would help if you could send us the logs when this happens.

    This can be done using the menu steps:

    System -> Maintenance -> Diagnostics -> Dump logs to USB.

    Thanks!
