OK...I am new....but have successfully printed a few smaller things. This is definitely the largest print I have tried so far.

A friend asked me to print this phone holder for his child's robotics class....

http://www.thingiverse.com/thing:1141100/#comments

In Cura I enrage it by 25.4 to get the right sizes.

200C, 0.4 nozzle...everything else standard

And then I get these type of results...no matter if I have applied glue to the bed or not...actually I got further without the glue...

Any idea what is going wrong? Looks like the top part is causing problems!

Please help.

Thanks!

    I was thinking about the speed also....any suggestions?

    The issue is that it starts with the bottom part no issues, then it take a turn on the long side and that one is not straight, thats where it starts going wrong and from there the top spahes go wrong also.

    I did level the bed to what i thought was good.

    Will try again tonight.

    Please suggest speed for initial print.

    its always important to get a good first layer down I often choose 30-35mm/s depends on many other factors though

     

    thanks.

    apart from slower printing is there anything that should prevent me from printing whole model at 30mm/s?

    Also, you do that through tune setting right?

    I would also look into the speed of your first layer.

    It looks to be levelled correctly since the brim (the part that is being deployed) looks good to me.

    The print should continue in the same pace but for some reason it doesn't.

    It could be that the speed increases after the brim. (a brim creates more adhesion.)

    Could you upload a screenshot from the orientation in Cura?

    You probably want to change the first layer speed in Cura, I believe it is under 'advanced'.

    Which version of Cura are you using?

    Usually there is a balance between speed and quality you make.

    If you print slower you usually get better results, but there is a certain speed (depending on the complexity of your model and the size) where if you go any slower it doesn't matter anymore. And generally people are looking for that sweet spot where you print fast enough with the best result.

    I am using the latest non beta version of Cura, 12.4.4 I believe...

    Will try some more stuff when I get back home.

    I am hesitant to let the print run over night....or is this OK and not dangerous?

    Not dangerous at all.

    With some complex things printing over 20 hours it is designed to run long prints, automatically overnight.

    Ok, I can relate to Cura 15.4.4.

    Looking forward seeing that screenshot :)

    OK...so I changed the layout and swapped the sides...that worked much better.

    Print speed was set to 30mm/s.

    Looks like there are some serious design issues as after the outline the print started to fail 2-3 times again today...so I gave up!

    Just hope its not the printer mistake!

    Could be a design issue..

    Care to share some pictures of the failed print?

    If you change the default view in Cura to Layer (top right corner) you can use this as a method to determine whether or not the print looks OK or not.

      • 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 5.3.0-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.
