Hey Pedro,

what do you mean with "crashed". Was the fan turned off during the print? If yes - are both side fans off? The UM2 head has 3 fans. Two big ones to each side and a small one at the back of the head which is always on when the nozzle/filament is hot.

Do they work if you go in the tune menu while printing (fan speed)

Or in maintenance -> set fan speed

In cura you can set when they need to start blowing, maybe also check that! (assuming they work from the printer menu)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
