Slicing problems after rotation


Recommended Posts

Posted · Slicing problems after rotation

I have sliced my model without any problems (see first picture) in an upright position. Due to better heating of the model I have rotated it by 90°. When I slice it again with the same parameter I get a broken result. The model was created with Sketchup. I imported it also to FreeCad and created the STL file with no difference.

Is there an error on my side or is this behavior knownslice_error.pdfslice_error.pdfslice_error.pdf?

    It's hard to tell by the pictures (and please, just embed them in the post, don't upload them as an attachment) exactly what you're trying to do or what the problem is. It's that in the second image it's missing a lot of the model?


    The model file itself (based on the shadow) looks very, very thin. Like, paper thin. Quite possibly thin enough that to draw a (by default, 0.4mm) line on that particular layer would exceed the bounds of the model by too much.


    If that's the case, in the quality settings, you could going to Quality > Line Width and lowering it, if you're using a 0.4mm nozzle, which most printers come with as standard, about the lowest you can go reliably is 0.26mm line width.


    You could also go to Experimental > Slicing Tolerance and set it to Inclusive. This will make Cura always round up when calculating whether to put lines/layers in, so that you're guaranteed to have at least the volume of the model filled (if it even has any volume it's so thin).


    If those don't work, it would really help if you could upload the Cura project file (.3mf, get it ready to print then go to File > Save Project in Cura).


    And for what it's worth, SketchUp is widely regarded as being laughably bad at exporting model files. You should never use it for 3D printing for that reason. Importing it into another program and getting that to export it won't necessarily change things.

    Well, carp. Hopefully my wall of text there can help someone, anyway.

      • 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.
