Cura 3.1 Dual not printing correctly


Recommended Posts

Posted · Cura 3.1 Dual not printing correctly

I am having a problems with doing dual prints with cura 3.1

It seem to be printing the item before the ooze shield. So it is not priming the second nozzle on tool switch.

Cura 15 would print the ooze shield first then the item.


Is there any options to change this?

I have tired adding in a prime tower but the same thing happens It prints the item before the prime tower.


This is with ultigcode.

    Just did a dual print, Cura 3.1 and Ultimaker3, including a prime tower. The print order is correct.


    Are you sure? can you show a video? 

    I will get a video later today.

    And this is an ultimaker 2 extend thats converted to dual.


    I normally use simplify3d for my dual prints with only an ooze shield printed turn iut great. But the support in cura 3.1 is better then simplify3d. So try to use cura for a dual print.


    Both nozzles will do the first prime. And first laryer is good. Once it gets to the second laryer,

    It will do

    T0 ooze shield, item, ooze shield


    T1 item, ooze shield, item.

    So T1 isnt prime and the item has holes in it.

    If i add a prime tower the same thing happens.

    Item before prime tower on nozzle switch.


    I will get a video in about an hour.

    But i use the cura play button and i can see if doing just as said

    I have no idea why you have this issue.


    I double checked, also just did a Cura3.1 dual print on the Mark2 Ultimaker2, and the printing order is just fine.


    What printer do you use? you may want to check you printer definition (the json file) against the UM3 file of the Mark2 file.

    You'll find the mark2 info here;

    Can you post a video of your doing as it should?


    I loaded in the mark2 files and added the printer.

    I didnt change the profile, just added ooze shield.

    And same problem. Preivee shows that it will do the part first then ooze shield.


    I also load in the ultimaker 3.

    I have to doble check, but pretty sure it did the same thing.

    The head move to the far right (for um3 tool change) but went back to the part and didnt item before ooze shield.


    Is there an opition in curs i might be missing?


    When i used cura 15.04 it would do the ooze shield, prime tower if i turn it on, then part.

    I don't feel like doing a video.... this is the order I got printing on the Mark2 today


    (M1 is Left material, M2 is right material)


    M1 - skirt
    M1 - item
    M2 - skirt
    M2 tower
    M2 - item
    M2 - item (2th layer)
    M1 - tower
    M1 - item
    M1 - item 


    etc.... always tower before item, did not try the shield, never use it

    Thank you for the information.

    I check that out and with ooze shield disable and just prime tower.

    It prints in the correct order.


    If i do the prime tower and ooze shield, correct order.

    Just ooze shield wrong order.


    I will do a few test prints and see how they come out without an ooze shield.

        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
