Grab meshmixer from Autodesk for free and you can use that to intelligently repair and decimate. You can also use Netfabb. But probably there are export resolution settings you can adjust for fewer polys and a similar printed result. Check the filesize of your STL and if it is really large, this is possibly having an effect.

    ill have a look at meshmixer.

     

    the file size is 2.16mb for a print of about 1 meter of filament 1.75mm (20-30mins print) im not sure if thats big or not for what it is

    that is not big. The check is opening it in meshlab, meshmixer, and checking the density of the triangles. If it is just black with tight triangles everywhere, you might not need that much resolution assigned to that geometry (so it might be introducing more lines of gcode to process than you need). If not, the problem is elsewhere.

    im not sure what you mean by check the density of the triangles

     

    the image looks like this

    That does not look right. Is there no way to show the actual wireframe? But that looks a bit fubar to me.

    I would have to say that if Inventor is being used then I would not worry about decimating. I use Solidworks and of course the two are the two leading software companies, arch enemies I guess, with a lot of similarities  and attention to engineering and quality. We have not had one problem from Solidworks in the 5 years we have been using it and I would expect Autodesk to be the same.

    Correct Autodesk's name

    Print a temperature tower to start.

      • 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.
