Posted · Air handling unit not found during print

I have this issue on at least 2 of my printers, both S5 pro bundles.

 

it will be printing fine, then all of a sudden with no one near the machine it get the air handling unit not found error and has to be reset which in turns ruins my print.

 

I then restart and its fine again with out touching anything.

 

Why does this happen and we make it not a fatal error in the firmware?

 

 

thanks,

kevin

    I've had this happen several times, and it is frustrating that it is considered a "fatal" error.

     

    I also have recent had several instances of "Air Manager Fan Is Unable to Rotate at the Desired Speed".

      • 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.
