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.
What printer is that?
The ""machine_max_feedrate_e" is often called out in the printer definition file. If you attempt to put in a retraction speed higher than the defined max E speed then (as you have found out) Cura won't slice.
In the MarketPlace is a plugin called "Printer Settings". Install it and many of those "other" settings will become available to you. You can increase the "Max E" within the Printer Settings and Cura will allow higher numbers in the retraction speed settings.
But that doesn't mean the printer will react to them.
Within the printer the Max Feedrates are stored in M203 and the Max Acceleration settings are stored in M201. Cura doesn't know what those Maxes are and so depends on the values in the printer definition file to tell it when a user has entered an invalid value. You could configure Cura to allow for a Max E Speed of 200 but when the printer sees that it will limit the speed to whatever the value is in M203.
For a reference I have a regular bowden setup on my Ender 3 Pro. I run the retract and prime speeds at 35mm/sec for PLA. I sent an M203 E50 to my printer so it would actually hit my 35mm/sec setting in the gcodes.
There was a poster here who had their retract distance set to 7mm and a retract/prime speed of 1mm/sec. Every retraction was a 14 second hit to his print time.
Let us know what printer that is because occasionally there will be an error in the definition file (which are submitted by members of the Cura Community, or by the printer manufacturers).
