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!
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.

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.
Well you aren't getting enough cooling on the tip of that tiny cone. So I strongly suggest you print 3 of these and lay them along the X axis so the ones not being printed on get more fan.
Then after you print those, measure the middle one and any errors remaining you can probably fix by adjusting in cad. note that all manufacturing techniques need some compensation in the design including injection molding (for example if you want 90 degree corners you have to compensate the angle).

OK if you want that level of accuracy I think you need to move to the custom settings.
Firstly you are printing too fast; set all your print speeds to 30mm/s (but not your travel speed or acceleration speeds).
Set your wall thickness to 0.8mm (i.e. 2*nozzle size)
Personally I would not print the brim via extruder 2; but that is presumably personal preference and probably does ton have any effect on your result
Personally I would always keep my line widths the same and the same size as the nozzle, i.e. line widths of 0.4mm, unless I was trying to overcome some sort of problem.
You will benefit from printing cool; you now have 100 micron layers at 30mm/s so you can probably take the temp down to 190 - if that looks great then try 185,but if you start to see under extrusion go back up.
@gr5 graciously suggested you print 3 copies - that is not negotiable for what you want - you have to:)
It looks like you might be getting some crow's feet but we can deal with that once we see the result of these changes
