How do you fix the problem of the print-core BB being read as AA? This is annoying because I cant even load pva with the BB print-core in because it thinks AA is in.

    As dorky as it sounds, try to clean the back connectors with Isopropyl alcohol. I like to use 99% pure to cut down on contaminants.

    I switched a BB core out with an AA core and then back again and I must have touched those tiny, delicate contact points in the back and it would not make the adjustment. Cleaned it with the alcohol and it worked again.

    I now make sure that I do not touch that area, but it is good to clean every now and then as air pollutants (Dust, moisture, etc) will eventually crud it up a bit.

      • Release Notes: S-Line Firmware 8.3.0 (Latest)

        Dustin posted a topic in Firmware,

        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.
