J-head on an Ultimaker?


Recommended Posts

Posted · J-head on an Ultimaker?

I got my fingers on an original j-head MK V Hotend, and it seems like a great product, very small/compact and seems pretty robust...

Has anyone ever put one of these in the UM original?

If so, how were the results?

    Aren't these designed to have the extruder mounted directly on top of them?

    Afaik there is no interface on the J-head to mount a Bowden tube, so you need to have a somewhat more complicated printhead design than for example with the E3D Bowden hotend. I had a look at the J-head (and clones), but that's why I chose the E3D in the end...

    I dont know...

    The one i got has a screw (called umbraco in DK, dont know if thats an international title...) in the top that can be taken out so the top has internal threads...

    A few pictures:

     

     

    So im guessing if one could find a coupling that fits the diameter and threads it could be used straight out as a very compact little bowden hotend..?

    Would the diameter allow you to cut the threads directly into the bowden with a die, and forgo a coupling entirely?

    Sadly not, already tried... I think the thread is M8, the bowden tubes i have both measure just around 6 mm. on the outside, so they are actually quite loose in the hole...

    Also i kind of like the push fittings, and how you can easily remove your bowden from them... That gets alot harder if the bowden is screwed directly into the hotend...

      • 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
