Completly new hot end for UMO ?

Recommended Posts

Posted (edited) · Completly new hot end for UMO ?

Hey !

is there any completly new design with all necessary parts for construct the new hot end for Ultimaker Original , (first version of UM )?

Original hot end keeps cloging and i dont want every time disassemble it.

Bed thing is that i cant print any more, so I need complete kit for assemble.

I am using 3mm filament and it is 90% PLA in it.

Please can someone help me to decide what kit to buy ?

I see E3Dv6 have some problems printing PLA .

I found only these :



Is there any other SET that is OK for UMO ?

Please help :)

thanks !

    not the cheapest option.... but very nice...  and I guess if you have the old board you also need a PT100 amplifier board from E3D-online.


    if you want to spend the time you can obviously source most needed parts elsewhere, like pt100, heater, block etc form 3dsolex.com, the aluminium parts in the head can be bought as spare-parts from an UM re-seller, or elsewhere online. I would advice against getting things like ptfe and olssonblock from a cheap china site....

    If you don't need to print hot (> 240°C), the UMO stock hot end is perfect and you should not change it.

    If it constantly clogs, there is a problem either with the hot end itself (coupler, mount, ...) or with the slicer setup (retracting too high, in particular after print).

    One thing though, it is very unlikely, but if you have a very old UMO (from the first batches, without Teflon coupler), that one is subject to clogs, and there is an upgrade kit...

    For higher temps, the E3D is the most affordable one, but as you mention the 3mm version is not the best option for PLA (although mine works fine so far).

      • 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
