Several complete small successive print and not simultaneous on the same plate to limit defects

Posted · Several complete small successive print and not simultaneous on the same plate to limit defects

Hello all,

I would like to know if there is a function with Cura that allows to print a part completely before moving on to the next part.
If this function does not exist, why not create it?
It would make a piece from the beginning to the end without leaving it, which limits many defects, especially visible on small parts.
This function should simply avoid bumping into the piece already printed. I do not see why it should not be possible with small pieces ...
What do you think of that please?
Thanks

    It does exist: in my old Cura that function is called "Print one at a time" (versus the standard "Print all at once"). I don't know the name in newer Cura-versions.

     

    However: this needs more room around the piece, to prevent the print head from crashing into already printed items. And if the models are very small, you will run into cooling problems: the nozzle staying on top of the model at +200°C, radiating heat, prevents the model from solidifying and cooling down. Increasing minimum layer time does not help in this case, since the nozzle just stays on top of the print. Moving it away is explicitly what you wanted to avoid.

     

    You might get this effect: the left models are printed without dummy cooling tower; the right are printed with dummy cooling tower. That dummy is only to allow the cone to cool down. But even in the white dummy tower, you can see that it had not enough cooling at the top.

    Its still called "All at once/One at a time", you have to enable settings visibility for Special modes in Preferences -> Settings visibility -> Special modes -> Print Sequence

    Then you'll find the slicing setting for for it in the Print Settings window (where you also set layer height, temperatures etc., its near the bottom under Special modes -> Print Sequence
