Help with tree supports in Cura 4.6.0 that keep ending up as spaghetti monster

Hello,

 

To get specifications out of the way. Ender 3 Pro, Cura 4.6.0, aluminum extruder upgrade, SKR e3 mini.

 

I got the brim fixed so that it prints correctly but now each time I try to print the back support ends up failing early on and becomes a spaghetti monster.


Tiny tree supports that I am not sure how to reinforce or strengthen.

From the layer view I can see that the connecting part is very small and thin so I am not sure if my printer needs to be slowed down. I recently installed an SKR e3 mini and had to force some speed updates in the EEPROM because it was moving way to fast and ruining every print. Settings got stuck somehow in the EEPROM so I had to reset it, so a problem could be potentially stemming from there. I am not sure if I need to limit it more so in Cura or in the firmware. I used stock speed maximums for the Ender 3.


The dreaded spaghetti monster. Clearly failing at those three small points, I am assuming because they are too small or perhaps the printer is moving too fast when pulling away and yanks the layer with it?

 

I have attached all of my settings that have been changed from the stock Cura settings in the imgur link below. I have also put in more pictures of the failed print. If you need anything else please let me know. Prints not using tree supports print fine so it is not a mechanical issue I believe.

 

Any help or guidance would be greatly appreciated. :) Or if anyone wants to share their settings for tree supports that would be great. I based mine off of a quasi guide on reddit that seemed to work well for people.

    Update:  

     

    Looking closer at the layer view it seems like there is a large gap that is causing the print to try and print in the air. Is there a setting that I need to adjust to correct this gap?

    The air gap is a setting in Cura called "Support Z Distance". It won't help you though because those tiny supports won't be able to handle the large structures you're trying to print on top of them. You should add the "manual supports" plugin and build a more robust support system for that area.

      • 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.
