Posted · Successfully get stucked PVA material out of nozzle

I tried all solutions from Ultimaker website but non of them work. 

 

Here is my solution: 

First heat the stucked nozzle to 200-215 degrees. (To melt the material) 

Put a segment of PLA material in to the stucked print core/nozzle until it does not go in anymore

Keep the material in the nozzle and apply some preasure

Lower the temperature to 80-90 degrees while keeping the PLA material in the nozzle (To let both stucked material and PLA cool down so they become a whole)

Pull the PLA out and the stucked material should come out

 

See Picture Below

The pink thing is PLA material I used to pull the material out of course I cutted it, the brownish translucent thing is the PVA material stucked in the nozzle.

    Perfect!  This is called a cold pull (but with a second material) and it's also easiest to remove the bowden tube from the print head before doing this.  but not mandatory.

      • 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
