Issues when printing gets to a certain height Ultimaker 2+ Extended


Recommended Posts

Posted (edited) · Issues when printing gets to a certain height Ultimaker 2+ Extended

I am not sure why my original post was deleted, but I'm having serious issues printing items that I had been able to print before with no problem and I'm not sure what to check out to see if it needs fixing or something to be adjusted.

The height this issue happens at isn't 100% the same each time. It does happen to be near the 6-7 inch in height when the issue starts to show up.

I've done things like slow the print speed down overall, force it to stay on a layer height for 30 seconds or longer. Changing these is no longer making the print nice and smooth in that area.

Images below.

This is illustrating that I've been able to print this same file perfectly fine before. The stick part of the print is separate from the red orb and the base it's sitting on.


Here is my multiple attempts to print the same file again and again, failing or getting it to print but it looks like garbage near the top.


Here's another print all together that also has the same issue of horrible lines after the height of 6-7 inches.



And here's what the print looks like on the bottom, totally fine an acceptable in quality.


I'm using 2 different Ultimaker 2 Extended that have both been upgraded to the + kit. The same issue happens on both printers and is a new issue. Printers are about 8 months old. I have them updated to Cura 2.3.1 firmware. Am going to update them to 2.6 (whatever version before 2.7 as I think that's still in beta).

    As the model is getting smaller the higher it gets it might be effected by the minimum layer time then over heating. What is this time currently set at?

    I have it set to be 30 seconds minimum per layer. I've tried up to 1 minute, with the same results.

    I also tried printing the knife model tilted ~45 degrees with supports running along the backside of the knife and that one was far worse than the one I just printed vertical. Around the same height mark it turned wavy, almost like forced layer shift, however it "returned" to normal layer position after a bit.

    You want to make the time smaller not larger as it will end up like your photo. Try 5 seconds.

    You may find it's one of the linear bearings for your z axis that binds at certain heights. If you unscrew them then slide them up and down the shaft you may feel tight spots.

    It can be

    -Bed Z screw needs lube. That’s the first thing to check.

    - PID bed. To fix that use Tinkergnome firmware. Ultimaker firmware don’t have that. And it makes better Z quality with it active.

    - Square flanged bearings faulty

    - Z screw nut faulty

    - Board gets too hot and you get miss steps. Fix for that is to remove the white cover and put a fan cooling the board.

    About all that there’s a good post where other user debug his z banding and fixed it. Also, as you will see if you read all the posts, there are links to other users Z errors. Link: https://ultimaker.com/en/community/20188-smooth-walls?page=1

    To debug if it’s the Z bearings/nut. You need to connect the printer by usb and use the Printrun/Pronterface free opensource software (google) and then command the printer moving it on small intervals to see if the Z gets stuck at some points.

      • 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.
