UM3 Cura2.3.1 adds 3 starting layers PVA at buildplate

Hi all together,

I tried hard in Cura 2.3.1 to eliminate these 3 unnecessary layers of support, which have been added by cura. If I use only one single extruder, my object is placed directly to the buildplate. But if I activate the second extruder using PVA, I have three additional layers under my object.

The 4th layer is regularly sliced in PLA.

I tried with a custom profile and a standard profile as well, both leads to the same issue. I figured out, that there is obviously a setting in mm, because the layers differ if I change the profile to another layer height.

Has anybody an idea, how to switch off these starting layers? I'm not willing to waste PVA, where it isn't needed.

Many thanks for your reply in advance and merry Christmas to all of you.

Best regards

Thomas

Edit 23.12.2016:

I figured out, that the round part causes that behavior. If I split the parts to single ones and load it afterwards in Cura, only the big round part has support on its flat side.

        (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.
