Ultimaker S3 Flow Sensor Issues?


Recommended Posts

Posted · Ultimaker S3 Flow Sensor Issues?

My Ultimaker S3 has been printing great for months now.  I did several prints last week without issue. Yesterday, one of the prints automatically paused with the printer reporting that filament was not flowing. I restarted the print a few times with different filaments, but I kept getting the error. This morning, I cleaned out the feeders and did hot and cold cleaning pulls on both print heads. I was hoping that would resolve the issue, but, unfortunately, it did not: my first print after the cleaning got the same error. 


I turned off the Flow Sensor in Settings and resumed the print and everything seems to be printing fine.  Any ideas?

    I would personally dry PVA for a good 8-10 hours if you have had problems with that spool, it takes in so much water so fast that it needs a real good dry.


    I would also look into getting a dry box or something to store the PVA in even why you print, the polybox is good for this. I personally use breakaway myself now with PLA because i don't have a problem with what i print needing support in places i can not get to, so i print with supports as PLA and the floor and roof of the supports with Break away.

      • 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
