Extrusion problems

Hi.

I had a major issue with a print overnight and came back to find our Ultimaker 2+ a little worse for wear with various pieces bent out of shape and melted PLA attached to multiple components.

After resetting/recalibrating everything, it is mostly behaving however the material (still PLA) is not feeding properly - it keeps concertina-ing inside the print head (see attached picture).

I've tried all the usual things with the feeder, cleaning the printer head, re-threading the PLA etc but the same thing happens again as soon as it starts to print (but seems OK when using 'Move Material'). I don't know if its related, but there is a whole load of melted PLA stuck in the printer head which I cannot get out (see other attached picture).

Does anyone have any ideas?

Thanks,

Nick.

    Two different issues. neotko posted something about removing the rest.

    But I'm not sure about this "concertining". That shouldn't be possible. The bowden should restrain it from twisting like that so I'm confused. Is the bowden all the way down into the white teflon part?

    I would try to remove all the outside before doing a debug. It could be a leak, print stuck to nozzle. I would prefer to remove one variable before continuing.

    Thanks both. I've done my best to clean out the printing head (although theres still some stuck around the wires I can't shift)... and re-fitted the boyden tube making sure it is down as far it will go. Its been printing mostly OK for a couple of hours so hopefully thats fixed. Fingers crossed, and thanks again for your help!

      • 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
