Lots of unexpected travels - what am I doing wrong?

Recommended Posts

Posted (edited) · Lots of unexpected travels - what am I doing wrong?

I'm a beginner - so please be gentle. 🙃 Probably doing something silly - but I hope it's OK to ask.


In some of the projects I'm trying to print, I have a massive amount of travels in places where I don't really see the need for them - one of the relevant projects is attached. Why does Cura do this? Is this something that can easily be avoided? I get a fair amount of under-extrusion and stringing at the beginnings of new layers like this (and am working on optimising the retraction settings), but it would be so much easier if the unnecessary travels could be avoided. Or am I misinterpreting things?

    There are a couple of things going on.  When I slice your model with your settings at least three of the walls disappear.  The line width is too wide and Cura can't fit the nozzle in there.  You can see they are gray in the shot below.



    This is with a 0.4 nozzle at .5 line width.  You can see the travel lines in blue.  You have "Avoid Printed Parts When Traveling" enabled so the nozzle moves to avoid the print.



    This is with "Z Seam Relative" at 0,0 and "Avoid Printed Parts" is turned off.  This is about as good as this model will get as far as travel moves go.

    Excellent - many thanks for these pointers. I still have a lot to learn and it's definitely not plug&play... 😆

      • 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.
