optimize travel moves


Recommended Posts

Posted · optimize travel moves

I created this little sample model to make testing faster (real model is similar but more complex and bigger and needs 20 minutes to slice)
pls don't recommend to print it upside down 😉



i was able to remove all transactions "inside the bowl" by using Combing Mode = all and disabling Z-Hop on retraction but when support is active there is one travel move through/over the model on each layer from support to the shell


to be able to print this part with materials like TPU where stringing never ends I need to get rid of this travels

another problem is that Z-Hop needs to be dissabled so this move goes over the already printed support and oftain touches it - I already needed to abort an PETG print because this travels broke the support



'avoid printed parts when traveling' is important to be checked
'avoid supports when traveling' does no change

changing 'Z seam alignment' doesn't help also

is there a way to let this travels go around "outside"?
how can I enable Z-Hop again?
model file:  uBowl.3MF

thanks 🙂

    Not so Easy .. You can eventually get rid of the movements in the part by using a Custom Support.




    But if you re-enable the Z Hop all the movements in the part will come back.  The only solution would be to use a post-processing script to add Z Hop to these movements. (https://github.com/5axes/Cura-Postprocessing-Scripts/blob/master/ZMoveG0.py)

    thanks, you created custom support for this screenshot?
    does it look the same when using tree-support?

    did you change other option also? I didn't got it looking like yours

      • 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.
