  1. ok so I don't know the model but I'm assuming the top part is what you wanted to print and you got a huge layer shift?

    if thats the case it looks like a mechanical issue, probably a loose pully (the gears driven by the belts...) you can tighten them with the screwdriver that was included with your printer.


    You may need to check the alignment of the printer, check this out for tool and instructions;






    ofc if I fully misinterpret the case please explain more, and share a picture of what the model should have looked like, settings used etc...

    guess what I really learned form this thread was that I don;t need the damn UM3 electronics to make the UM3 head work.   

    You can use the um3 head on the um2 by simply making a PCB with only the connectors touching the core electronics and wire to the mainboards heater and pt100 connection. No need for any fancy electronics. I've shown it here somewhere including the link to the correct component but on the phone and too lazy to find a link now 🙂

  3. What brand of ABS did you use?, Any should work but I think most brands of ABS need a higher printing temperature than the Ultimaker ABS default. Also (partially) closing the top of the printer to get a heated chamber can help when printing ABS. 


    something like this...  though I myself just put a curver box on top of my UM3 in the rare occasion I printed ABS,



    Anyhow, depending on the specific need, many alternative materials are easier to use for sure...

    One visible change we made is that the filament parking location moved about 10cm up and is now located outside the print core at a visible location in the bowden tube. Advantage of this is that a faster changing filament or changing print core can be executed since we can skip heating the print core.


    I'm confused, there was no need to heat the core before, I always change filament manually and I never had to heat before.


    the "10cm up" can probably be an issue with manual filament loading when  people feed the material too far, how will you prevent grinded material in this case? I'm not sure which issue the extra 10cm is supposed to solve, but I can see it generate new issues ...


  5. In general there are hardly any limits to the masterials you can use on an um2. probably the biggest limit is use of materials that need a very high temperature (fe peek..)


    In the case of Xstrand and other "filled" materials you better use a hardened nozzle, like a 0.6mm Olson ruby. Filled materials can also wear out you feeder, so if you want to use a lot of filled materials you may want to upgrade the feeder to a bondtech.

  6. 1: you can drop as many items on the build plate as fits your printer.  This is a good idea to combine smaller prints inmto one big one for overnight printing, so you utilise the machine fully. It's less logical for already long prints, as it adds risk, if the print fails you have multiple failed prints.


    2: sure, cuttout a number on the BOTTOM of the print in CAD


    3: not sure what you want to print from the picture, but the simple structures (the white building blocks?) could be a lot faster made traditionally in wood f.e. so you only print the complex parts?

    I would advise you to keep a close look on your printer when using "Gradual Infill" settings. this setting has caused my printer to fail badly more then ones. And one of the times it was close to do damage to the print head.


    Now I'm curious... what happened? and how is it related to gradual infill?

  8. Yep. That cura behaviour annoys me ever since cura 2. It's even so that a different color of pla forces you to override. And indeed having to go to the webpage for the override is super confusing. The interface is a bit better in cura 4 but it's still a big annoyance.


    Looking at the fact it's a years old issue you probably have to live with it....

    Also a solution 🙂

    But I would have expected a perfect tool from you - what happened? 🙂 

    Actually in my um3 I had the magnets pop out and glued them in... Just trust it will be fine. For now I'm just living  on the edge without a tool with the s5  🙂

  10. Think my oldest Ultimaker2 is from the beginning of  2014... still going strong...


    Sounds to me like a mechanical thing, did you check all the screws and springs? maybe tighten the springs more?

    Just make them pretty tight, but be carefull to keep a bit of space between the power connection block (back left) between the bottom plate and the heated plate.


    As you mention it's on all 4 machines, common sense dictates that is likely something in your workflow, and not the machines... did you change anything in your way of working with the machines?

    @ultiarjan , thanks for trying this version! We also probe the 'movement area' of the first layer since we need to move there with the nozzle, so we also need to compensate for build plate deformation in order to prevent potentially scratching the bed. That is why you are seeing the bigger probe area you illustrate.


    Think that reduces the added benefit a lot, I feel you can still reduce the amount of probing more.


    Also, why still probe the unused nozzle, waste of time imho

  12. also, soon after the print start i lost connection with the printer, on a wired connecting...


    "mange printer"  "connect", does not reconnect to the machine...




    rebooting Cura will not let me reconnect, have to reboot the S5 first.....

  13. first feedback;


    Install, ok

    sensor test, ok


    object based probing, not ok  (Cura 4 beta 2)


    Sliced a tiny part, but it still probed the height of both nozzles, and it probed about the hole green area, not only the relevant area around the object.


    And even for the first print after firmware update the ,material was retracted so much that also the prime blob was not enough, so if you try this firmware just manually push the filament a bit....




  14. Just change material manually, open the lever on the feeder and pull it, it will give you a feel for how many resistance there is. I only change material manually on S5 and UM3 and never had the material stuck, the retraction at the end of a print seems to work just fine for me.


    It may be a bit oldschool but the manual way is just a lot faster... set the material type by selecting "select type" in the menu behind the dots.. If you load manually push it all the way to the end and then retract a few mm to avoid a too big prime blob..



  15. No, you can't run Ultimaker firmware on a duet board, but you also don't want that. the duet firmware is really good and open for easy modification, you'll just have to setup a few macro's for the tool change g-code. probably others have done it already...


    There's plenty benefits to use a duet over an Ultimaker board, to name a few, the machine will be network connected, and have newer stepper driver which make the machine much quieter.
