5D means that there is an "E" and "F" axis. The old-school machines used M10x codes to start & stop the flow, and it was really problematic to get the right speed when speeding up and slowing down. This was solved with 5D, where they added the "E" and "F" axis, to achieve high speeds.

...and E is 'extrusion' and F is X/Y speed.
Basically, 5D allowed movement of all axes (x, y, z, f, and e) on each line of gcode. With that, it's a LOT easier for the firmware to play games with speeding things up and slowing them down so we can have features like acceleration.
Volumetric 5D came later and redefined what E meant. It used to be (straight 5D) the length of filament you wanted to come out of the nozzle and changed to mean the length of filament going into the extruder drive. This made it WAAAAAY easier to come up with new printing profiles, since it allowed slicers to just say "I want this much filament" and not have to worry about nozzle size and temperature and all that crap that can vary from machine to machine..

Maybe even more important, it makes slight variations in nozzle size unimportant.
Still, IMHO, the current implementation is still not the best. Because if you change filament now, you need to slice again. The filament diameter could have been a firmware setting, and the E value could have been a volume.
But it works, and works very well

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.-

It's the old, backup, failsafe, bad, blob generating firmware which is installed on your machine by default. It's depricated and replaced by Sprinter and Marlin.
