7.2 Print at too high temperature
If you are already using a cooling fan and you are still seeing this issue, you
may need to try printing at a lower temperature. If the plastic is extruded at a
lower temperature it will be able to solidify faster and retain its shape. Try lowering
the print temperature by 5-10 degrees to see if it helps. Please read “Cura Tutorial”
to learn how to set the temperature. Be careful not to lower the temperature too
far, as otherwise the plastic may not be hot enough to extrude through the small
opening in your nozzle.
7.3 Printing too fast
If you print each layer very quickly, you might not need enough time for the
previous layer to properly cool before you try to deposit the next layer on top of
it. This is particularly important for very small parts where each layer only requires
a few seconds to print. Even with a cooling fan, you may still need to decrease
the printing speed for these small layers to ensure you provide enough time for
the layer to solidify. Cura includes a very simple option to do exactly that. Click
“Advanced” and you will see “Minimal layer time” under “Cool” tab. This section
is used to automatically slow down the printing speed for small layers to ensure
they have enough time to cool and solidify before printing the next layer. For
example, if you allow the software to adjust the printing speed for layers that take
not less than 10 seconds to print, the program will automatically slow down the
printing speed for these small layers.
This is a vital feature for combating these overheating issues.
