Silocone Nozzle Covers Don't appear to fit.

Recommended Posts

Posted · Silocone Nozzle Covers Don't appear to fit.

My silocone nozzle covers have started to come apart so I've ordered more, and am now trying to install them.  I have an Ultimaker 3 Extended.   But the metal bracket that the silocone is to be installed in on my device differs from the one in the pictures.


Mine has two "Rounded Ice cream cone" shaped holes, whereas the shape in the pictures, and the shape of my new silicone nozzle covers... is just a pair of squares.  The new ones are a fairly different shape, compared to the new ones I bought.  The old ones had "wings" on the side and a "slot protrustion" in the center.  The new ones, dont have either of those.  So perhaps I bought the wrong one?  But it looks right from the images online.


Note... The whole extruder/fan assembly I have currently is not the original.  The original failed catstrophically, and I have a replacement.  I assumed it's the exact same one, and has been working fine... but perhaps I have one that differs from the OG assembly.


Any recommends for me to resolve this?  Get different silicone nozzle covers?  Replace the metal brackets that they attach to?  Where would I find the appropriate Mix n Match part that gets this done?

    @undertone_dj - email support@fbrc8.com.  Send them the serial number of your printer in the email (sometimes they won't answer questions without it so this can save some time).  Tell them you changed the print head so that your printer may have changed versions or something.  Show a photo of the old and new silicone part.


    background: fbrc8.com assembles all Ultimaker printers sold in USA so they probably built your printer.


    I think Ultimaker may have modified the part to work better but it's possible you got the wrong one,  I think if you google on their site you can find photos of how to change the rubber part.  But this part exists for UM3 and S3 and S5 and the S5 one definitely is incompatible with UM3.  Not sure about S3 but suspect it is the same as S5.

    there's been a change some time ago.

    Below is a picture which compares the "original"/old style covers for original UM3 printheads and the new ones for the revision.

      • 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
