UM 3S loading PVA issue


Recommended Posts

Posted · UM 3S loading PVA issue


I'm trying to load a spool of PVA into extruder 2.


I follow all the steps on the screen & the filament rolls up to the print head (BB04) but that's when it goes wrong.

Its says to wait for the filament to extrude, it never does. The filament moves slowly at first & then a very small amount extrudes then stops.

The confirmation time period times out & the machine appears to think that PVA has loaded (even though I never pressed confirm).

When I try to print I get a warning that there is no material loaded in #2 then when I trick it into believing I've changed it nothing comes out of #2


I have loaded & unloaded the PVA

I have inspected the print head & made sure its clean than reloaded it.

Still nothing!

    Just to be sure you do the load procedure correctly:


    1. you choose load in the menu
    2. the spool will be detected by the printer and you confirm it
    3. you put the filament into the feeder and after it was catchend by the gears and you feel that it moves in very slowly you confirm it on the display,
    4. filament is loaded to the head and after some time it comes out of the nozzle
    5. then you confirm a second time

    Are these the steps you did? I have the feeling you missed the confirmation after putting the filament into the feeder.

    I've followed all those steps a number of times, the problem comes with step 4 when loading the PVA.

    Only a very, very small amount comes out of the nozzle if any at all, cerainly not a consistent flow.

    After  waiting a while for a consistent flow to appear the confirmation message times out & the printer appears to assume that the material has loaded when in fact it hasn't. This becomes aparent when I try to use the material & nothing gets extruded from its nozzle.

    There is a menu item under print core which guides you through the process.


    Here is more information for the UM2, but it is basically the same, just not guided.

      • 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
