  • Yeah, if the nozzle is hitting the part, then it’s very likely a cooling issue. If an steep overhang isn’t cooled properly, it’ll curl upwards.

    Either you’re printing too hot, or the fan is too slow or failing. For PLA, you can leave the fan at 100% after the first or second layer, and print between 195 and 205°C. Printing too fast also means the fan may struggle with the amount of hot plastic.

    Can you paste your slicer settings?




  • Any videos of when the print fails? Is it all prints or just the Benchy? Does it always fail at the same height?

    From the available info, I’d guess it got knocked off the bed because the nozzle hit the curled overhang, which indicates the first layer is too high, decreasing adhesion, and the fan is not blowing enough, so the overhangs don’t cool enough, which allows them to curl upwards and get in the way of the nozzle.

    More info = better diagnosis.
