SolvedHow to get cura's time estimates closer to reality?
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.
In this case it appears to be something in the Settings Profile but I'm unable to find it. Simply opening your 3mf file and slicing it I get a print time of 4:47.
Just switching to the Standard Settings profile (with infill adjusted to be the same as your settings) the print time drops to 3:09. Switching the infill to Grid results in a print time of 1:54.
So maybe something is going on with that settings profile, or maybe with the Creality Ender 6 definition or the Creality Quality files?
As an experiment - try using a stock profile like Standard/Draft with 20% Grid infill and see if it makes a difference.
The Grid infill results in a few lines of gcode. The Gyroid infill results in a bazillion lines of gcode because of all the curves. Part of what is going on may be a cumulative error when Cura attempts to add up the print times for all those short line segments. I have no idea if that may be true or not but in this case we can see that Grid v Gyroid makes a big difference.
This topic comes up a lot. For myself, the Cura estimated time versus the real print time is consistently within 12% of each other and Cura always over-estimates.

Thanks for looking at this.
I've now created a new profile, just copied the speed and accel settings into it, tried a few things and yes, they are indeed a lot more accurate now. Nearly spot on.
I'll simply on from this new profile.
