Looks like an unnecessary piece of support

May be a  bug?

 

Please have a look here guys, I've tried to create a bunch of screenshots to illustrate the problem.  It seems that cura has generated a bit of support within a support blocker.

Normally the program only does this if the support is required above.  However, this bit is not connected to anything above - it ends on the model.

On a sidenote; I can't print this bloody dog.  The dog's right ear just does not print, I've added extra-wide supports, plus extra manual supports now, printed with 0.12 line height, and that right ear moves out of place every single time.  The end seems just too pointy to be printed.

    When I change the Support Placement from Everywhere to Touching Buildplate that piece of support goes away and the spot between the right ear and the head is not supported any longer.  So it looks to be that Cura is building the support from the build plate up to the root of the right ear and the body is in the way so it starts from the build plate, pauses when it gets to the stomach/chest and continues from the back up to the root of the right ear.  That ear area needs support so I think in this case you will have to live with the piece on the build plate.  It isn't there for the body but rather for the ear where it connects to the head.

    Placing a support blocker at the root of the right ear will also cause the questionable support on the build plate to go away.

    In this image I've set placement to Everywhere but added a support blocker at the ear.

     

    Remember when you wrote "Normally the program only does this if the support is required above."?

    I guess it could be called an artifact or maybe a pre-ifact?

    @nallath do you have any thoughts on this?

      • 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.
