Filament retract during "Lift Head" for "Minimum Layer Time" in Cooling
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 5.0 and 5.1 you get something like this:
G1 F1500 X106.692 Y105.679 E230.0867 ;> Last extrusion
G0 F9000 X106.692 Y106.2
G0 F600 X106.692 Y106.2 Z1.04
G0 F9000 X105.87 Y105.87
G0 X105.6 Y105.6
;Small layer, adding delay
G1 F2100 E225.0867 ; > Retract 5.0 if there was no retraction since last extrusion
G0 F9000 X105.6 Y105.6 Z4.04
G0 X119.742 Y119.742
G4 P48796 ; > dwell is dependent on Actual Layer Time, Min Layer time, and Min Speed.
There were a couple of instances in the gcode where there was no retraction within the "Small layer, adding delay" section. In all of those cases there was a retraction directly after the last extrusion and so a second retraction wasn't desired.
If you open the gcode file in a text editor and search for "G4" you will see the delay sections. If there is no retraction within the little section then look above for the last extrusion. There should be a retraction right after it.
If your "Max Combing Distance with no Retract" is too high, or if the "Retraction Minimum Travel" is too high then maybe there wouldn't be a retraction(?)
