I'm thinking it may be to how thin the structure is but why doesn't Cura create supports for the ring around the cone?

 

First image is of layer 1. Notice the Skirt doesn't extend around the entire part.

Second image shows layer 3 - the first layer with the ring around the cone.

What am I missing? Never mind why the part was created this way - I'm just the printer. 🙂  (I sent feedback to the designer already).

 

Thank you for your help.

    So your object probably doesn't have a flat bottom.  One end is around 0.2 to 0.4mm lower than the circular part.

     

    One solution is to fix it in cad.

     

    Another is to go into "preferences" "config cura" and uncheck "automatically drop models...".  Then click on the part and select the move tool on the left and enter -0.5 for the Z position and reslice.  This will chop off the bottom 0.5mm of your part which is hopefully not a big deal.

    If I am reading this correctly, he knows the part is made a certain way, he just does not know why it will not put supports under the round part.

    To do that do "File" "save project..."

    Thanks for putting that in 🙂

    Oh, right!  Maybe this one: "support Z distance".  Try setting that to zero.  Or maybe something else - post the project file and we can figure it out quickly.

     

    Are you doing PVA support?  Don't answer that - just send us the project file and we can see for ourselves.

    OK, I took a look and this is what I found:

     

    The PLA/PLA combo is not really needed. If nozzle 1 & 2 are using the same material, there is no real gain.

     

    However using PLA as support has different tolerances between the support and the model itself. More gap for better removal of the supports. There is no harm in using the PLA, just know it has different requirements than if you used PVA as the support such as this file I saved for you so you can see the difference. Just load and hit slice and you will see it works.

    Now, if you wish to use PLA as the support, just raise the model about 1mm from the buildplate. It will slice with the support all around the object as needed.

     

    You may have more questions and here is where to get your follow up. 🙂

    Yes.  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.

      • 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
