Retract Before Outer Wall Does Not Appear to Add Retract...
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.
Yes, but the travel move to the outer wall from the wall next to it is only 0.4 mm long and this is shorter than the Retraction Minimum Travel setting so no retraction is done. I just noticed that setting is currently not visible (it was disabled a couple of months ago). I will ask the UM people what's happening with that.

Ah, thank you for the information. I did a bit of searching, and I see that the "Retraction Minimum Travel" setting has been explicitly hidden due to several bugs:
Adding a line to the appropriate Cura quality configuration file in order to set the value of retraction_min_travel (e.g. retraction_min_travel = 0.0) seems to add the retraction to the G-code, at least in the test scenario that I provided in my prior post. I'll try to test things later today.
Incidentally, I have a Creality CR-10 printer, and I have been trying to resolve a problem with a skin seam that appears when the nozzle moves to the outer wall. This problem does not appear to occur in Cura version 4.0 and prior (the seam alignment behavior appears to be a bit different in versions after 4.0, regardless of the "Z Seam Alignment" setting, which makes the problem more apparent). It appears that I might not the only person who is experiencing this problem (https://github.com/Ultimaker/CuraEngine/pull/1108#issuecomment-555751196):
