This is certainly very impressive. These supports look much more clean. I will be testing how easy they are to remove. For now enjoy some of these comparison images. I really wonder how this stacks up against the organic supports Prusa Slicer is teasing, from what Lost in Tech said, these are the same or very similar. |

I tried moving my print off-center but it produced this error, when I click on preview. Hope this test helps. This is not a water-tight model as per Cura (yet), if it helps. |

Just some info. These new settings never showed up in my installation of this alpha before I went in and added them by myself in the setting visibility window. I dont know if it is supposed to work like this now since this alpha is entirely about these. (It might confuse a few people) |

Great work! I did notice one potential issue; in one print there is a cave with a narrow entry, and it seems as if the supports enter the cave and then expand. Ultimately, this would cause supports which can not easily be removed. I plan to print it nevertheless and see if I can break the branches within the cave. It also seems to me as if the branches inside the cave do connect with branches outside of the cave. In case you are interested, the print is a snake skull, sliced in the orientation of the .stl file. The cave is the brain area. |

Testing this on linux Mint, This piece has always been a pain for me to print, want to test it with the new tree supports, everything looks fine and love the new tree placement, problem is, and i don't know if it is a rendering issue or if it will actually print hollow, but when i go through the layers it is just a shell with no infill. infill currently set to 20% and same issue at 100%. will try a test print to see what actually happens. If there is a nightly build i have no problem testing that as well, just point me to it. |

finally able to test, sadly Cura does not like my start gcode for some odd reason. Mind you this is on Linux Mint using Klipper, for some reason it keeps stripping off some of the code down to |

I have used this new cura Xmas for a week or so. today I decided to do a Godzilla so I can try to use the tree support. when i start to slice it just gets stuck to %50 and doesn't finish slicing, I have left it sitting for an hour, and still nothing. I'm on windows 11 and I know there is some issue with not being fully compatible with win 11 but i wanted to comment for the devs. any one have this issue and know how to fix it or get it to work? |

Fyi ThomasRahm/CuraEngine#8 to add to known issues. I'm not yet sure if i want to just cull them or try to find another way. |

Support interface is missing, making it harder to peel off large support chunks that are hard to reach. I like the new version's path making, but support interface is crucial for me. |

El nuevo algoritmo de soporte no llega a identificar los voladizos más pequeños a comparación de un soporte normal, si ahorra material pero la falta por identificar los boladizos más minúsculos |

Did the 5.3.0-Alpha supports make it into the 5.2.2 release? I'm a little unsure which version I should be using right now. The 5.3.0 supports are really useful for me and I don't want to give them up if 5.2.2 doesn't have them. Thanks! |

New Tree + Custom Support Cylinders Addon = TREE Supports starting mid-air where the two interact, when density is set to zero (common for tree supports). When using tree support internal density, the floating support is similar to how infill supports internally. Prior versions of Cura combined the two correctly with zero support density EDIT: Updating the addon has not changed anythying. |

Hi, firstly thanks for this special release, I love the new tree supports 👍 I've had this issue which appears to be supports in the middle holding up thin air? I think is different to #12326 as the supports seem to be correctly attached to the base, but there is nothing above them? Apologies if this is my model or expected behaviour. |

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.
New tree support implementation
These new tree supports use significantly less filament than our current version of tree supports. Where our current tree supports have a tendency to merge multiple branches into one larger branch to limit the amount of retraction, these trees have a different shape and have smaller branches that are able to reach tricky corners. With less filament extruded, you’ll also see a significant decrease in printing time.How can you start testing?
You can try out these new tree supports today.Notes to keep in mind when you start testing
The following settings have been introduced:You can learn more about what the settings do in Thomas' original Pull Request.
Known Issues
Please note
Due to the holiday season, responses from UltiMaker might be slower than usual. Please remember that this UltiMaker Cura alpha is not suitable for ‘normal’ use. It should be only used for testing. There is a higher chance that you may run into one or more bugs (some known, some unknown). These might reduce print quality. For example, keep in mind that we cannot guarantee that profiles get migrated over to UltiMaker Cura 5.3 stable correctly. So be sure to save them before upgrading.A HUGE thank you to anyone who contributes to this alpha test and don’t forget to give Thomas some love for the incredible work he has done to improve UltiMaker Cura.
