problems of temperature? big blop at the end of prints

Recommended Posts



since quiet some time i have a problem where the last part printed of the parts is like the nozzel go ups in temperature or something.

the thing is that i dont have any spetial configuration, also i am printing in PLA. 210°C with bed of 60° .

i kept a really low speed of printing and travel but it isnt as all over hangs are like that is only at "the end" of the printing, like it change temperature or some configuration at the last slices. 

i tried to re install cura from zero. i have non pluging or anything else...



also i need to add one last info, i have printed even the same piece with different results, everytime it has this "blop" but sometimes bigger some times smaller.....

Welcome to 'Everyone gives you settings to play with." :)

If the problem is happening at the highest point of the model, and especially if it only happens with this model (or similar models that come to a point), it may be that the highest layers of the model are printing too quickly -- that there's not enough time for the material to cool before new material gets laid down on top of it, and the peak collapses into a disc as a result. To see if this is it, try changing the "Minimum Layer Time" from the default 5 seconds to 30. (If this turns out to be the issue, a setting of 15 or even 10 may well be fine and will speed up the print.) Also turn on the "Lift Head" setting so that the warm nozzle isn't parked directly on top of the fragile area of the print during the waiting time.

    • "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.
