Actually, perhaps. I noticed some strange support behaviour. In a symmetrical part, it would do the left side, but not the right side. I havn't tried rotating the part though...
The support is generated with a projected bitmap. Which causes these kinds of artifacts.
Maybe you could explain this for my? I do not understand how the same model is supported different depending on alignment?
So i have to check every possible alignment before printing for best supports?

What Cura does, is kinda like this:
So it takes the object. Looks from the top. However, it does this at a lower resolution. In the last picture, if there is enough purple, support is added there.
Some smoothing is done on the final support. And the resolution at which this is done is actually higher then what I show here, but I hope it helps in understanding what is happening.

Pretty cool demonstration! :cool: It could be called 'inside Cura'... 
I feel a little dumb now but I don't see why a projected bitmap from top would be different when he is rotating the part on plane parallel to the bed? Or is it related to the "squares" background? Even so, it is hidden by the part...
I hate when I don't get it =) (especially when 2 people like your answer Daid -unless they just pretended understanding it :-p-)
Location from where the pixel map is generate is always the corner of the outer box of the object, this causes the "pixels" to align differently on the model.
Simply put, it's an aliasing problem.
I think I understand, but then shouldn't it be minor artifacts? On Dirk video it's like a full side of the part not being (or being) supported, looks big for an "aliasing" problem?

UltiMaker Cura 5.3 stable released
ArunC posted a topic in Ultimaker Cura,
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
MariMakes posted a topic in Official news,
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.

Cura Alpha With New Tree Support 🎄
MariMakes posted a topic in Ultimaker Cura,
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.-
