  • 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.




  • Yes, I understood exactly what you said because, as I said before, it’s not hard to understand, it’s just badly formulated.

    Natural science is amoral, a jaguar doesn’t care that a gazelle is pregnant when hunting it, since neither of them know what morality is. Scientific research is not naturally moral or immoral, it’s instance dependant. You wouldn’t call Volta immoral for stacking zinc and copper to make a battery, and you wouldn’t think twice before calling Unit 731 immoral.

    You don’t get to make a normative claim, wrap it in a false equivalence between human constructs, like scientific research and morality, and the moral independency of natural science, word it inches away from historical fascist research ideals, and then complain when people fill in the blanks in the most plausible way. If you wanted a real discussion, you could’ve developed, from the start, on what you mean, and worded it better. But you didn’t, you’re just rage baiting.
