CURA "slicing" but doing nothing w BIG models only


Recommended Posts

Posted · CURA "slicing" but doing nothing w BIG models only



Cura (4.4 on one PC, 4.3 on another) doesn´'t slice (CPU&GPU 0%); there is no blue progress shown. Models upwards of 500 MB (binary STL) are affected. Sometimes, a reboot helps, but for some models I am stuck.


I have sliced larger models on these PCs before without issue, thus pure size doesn't seem to be the issue.


Adding a small cube that touches the build plate did NOT solve the problem.


The firewall is NOT an issue, as I can slice other models easily.


I tried exporting from a different program (Rhino 5.0 instead of GOMinspect) - no help.

    So I downsized the files to less than 60 million points (120 million polygons) and now it works.


    So, why am I sometimes able to slice files that are way over 1 GB as binary STLs, and now these will only work when ca. 540 MB?

    Over a million polygons is, well, a lot.  For the model in this article you can see that even for a detailed car... well check it out:





    Actually, whether it is a lot or not depends on two things: printer resolution and print size. And I can tell you that in this case, the required reduction is visible in the printed part. Print space is 1 cubic meter.....


    OK; I can manually select areas for local reduction where the detail isn't that important, but that's going to be a full day of work.


    And Meshlab can't even handle meshes of that size properly. Only GOMinspect is comfy with them.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
