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.
Make sure you have a good cable connection into the print head. Failures on the print head board alone can cause the UM3 to not boot up. It's very common for pulling forces to pull the connector right out of the print head (partially).
There are 4 longs screws. Remove the rear 2 screws only and then a panel on the head comes off. Make sure the cables is pushed firmly into the connector (if you choose to remove the cable beware there is a clip holding it in place that needs to be squeezed).
Actually, watch this video before doing anything: https://ultimakernasupport.zendesk.com/hc/en-us/articles/115004226246-Printhead
Try powering up one more time.
If that doesn't work, because it sounds like you had a "head flood" there can be much damage while removing all that plastic. I'd take the head all apart. check all the cabling. Try powering up with it disassembled but electrically connected. If that still doesn't work I'd order the PCB in the print head. It's not expensive and can be ordered separately from any reseller but for you I recommend igo3d.
Alternatively if you have time (and not a lot of money) then I'd get the "olimex serial-cable-f" and if you know linux somewhat you can look at log files and see what code is giving you errors. This guide will tell you how to use the cable and at the bottom where to find some important log files. Google can also help you figure out why it isn't booting.
For example one error might be bad blocks on the eMMC solid state drive. Or some driver on the USB bus. Or most likely the i2c code written in python (so you can read all the ultimaker written code including comments right on the UM3) is having trouble communicating with the print head.
