What is the MiniCalTest supposed to tell us?

Posted · What is the MiniCalTest supposed to tell us?



I just bought a lightly used UM2 from a fellow community member (it has ~28 hours on it only, so like-new). I printed the MiniCalTest file that was on the factory card. I am not sure how I am supposed to interpret the test results? I see some stringing and for the wedge, I don't know what that's about.


Pictured below, please advise and is there any thing I can tune?

    Hi Nighthowler, thank you for your message and welcome to the community! 

    Happy to hear you found an Ultimaker. 


    The top minical test doesn't look too bad. You can see some stringing in between the pillars which could be something for you to look into to improve. This minical gives you an opportunity to see if your belts are tight enough (sharp corners), if your cooling is working (stringing, molten layers), and if your extrusion is on par. And it could show some other artefacts if something was not correct in your motion system. 


    I am curious about the material. Did it come with your Ultimaker 2? If it did, it could be a rather old reel of PLA (a long time in the past we used to ship the Ultimaker 2 with a reel of Ultimaker blue PLA). If so, the age of the filament could have something to do with the stringing, and I would recommend to try a newer roll before you dive into the settings which might be dialed in correctly. 


    Good luck!

    @SandervG your guess is spot on. It did come with a roll of blue PLA and my guess is that it dates back to June 2014. 


    I have ordered three rolls of Ultimaker materials and will test with that beforr tweaking anything.


    I also printed the hollow tetrahedron (I think called line tetra) and it came out perfect with zero stringing. The retraction on it was perfect.


    Thank you for sharing what the various fearures on the MiniCal meant!!

      • UltiMaker Cura 5.3 stable released
        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.
