Constant Nozzle Jams


Recommended Posts

Posted · Constant Nozzle Jams


our Ultimaker experiences constant nozzle jams.

Things which I'd really like to have answered:


  • [*:3jlk2rj1]How are people able to extrude PLA at 190°C and even print with that? I am not able to extrude PLA unless it reaches 195°C. Is our temperature sensor off by 5-10°C?
    [*:3jlk2rj1]How much(less) force should be necessary in an optimal setup? Since the beginning of our Ultimaker experiences, PLA wasn't very easy to push through the extruder. How can we measure the force and how to determinate if too much pressure is needed or if it's "just right"?

    Recommended printing temperature is 210C. PLA starts to flow a tiny bit at 180C, but you need a higher temperature to really print at the speeds that the machine can achieve.

    I bought my Ultimaker last November. Didn't get it working until January. Once it was working, I was having nozzle plugs constantly, too. I increased the print temperature to 225c for most of my PLA prints. That made the flow much smoother, but the high temperature creeps up past the aluminum heat sink and causes plugs up in the Peek and nylon area. So, I mounted a fan which only blows through the space between the aluminum heat sink and the bottom wood plate. That gave me about 6 weeks of constant printing with zero plugs until my Ultimaker stopped working completely a couple days ago. Sadly, it died 23 hours into a 25 hour print.

    oooh why did it die ?


    Good question. When it stopped printing, it stopped talking to my computer. No matter how many different cables, USB ports, and computers I try, nothing sees the printer anymore. I'm guessing the main board finally went the same way as my Ulticontroller went. What irks me most is they knew they were shipping bad electronics and kept shipping them anyway with no offer to replace them when they go boom. They figure people will buy the electronics again. They figured wrong. I'm ordering a CubeX Trio from 3DSytems later this week. I'm sick of wasting time and money on a company who doesn't give a crap about their customers.

      • 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
