Cura fills hollow cylinder where shaft is supposed to go


Recommended Posts

Posted · Cura fills hollow cylinder where shaft is supposed to go

I could use some help slicing. The circled area is supposed to be a hollow cylinder with one square side so that it can slide on to a keyed shaft. However, Cura is filling it in as can be seen by the arrow. If I turn support off it doesn't fill it, however, I need support on because the model gets much wider at the top. Any help would be much appreciated. I have attached the stl file as well.

    You can do it by creating a support blocker using this tool on the LHS




    Position the block so that it completely meshes with the region that should not have support




    When you slice, the support isn't in that region




    The support blockers can be moved and resized like any other mesh.

        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.
