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.
There are no dumb questions. I strive not to give dumb answers.
The entire USB Printing thing isn't very sophisticated. Cura looks for a port it can open and then tries several baud rates and sends M105 each time. When it gets a response that it understands, then it uses the port.
The printer isn't very complicated either. It will accept most any connection (whether it understands it or not is another question).
As you probably suspected, that leaves us with your new laptop. The screenshot below is the Windows 11 device manager. If you squint you can see that "Ports Com and LPT lists a single port as "USB-SERIAL CH340 (COM3)". The COM number will change depending on which port I have the printer plugged in to. But the port driver (in my case it's the "USB-SERIAL CH340" driver) is what allows the computer to "see" the printer. If the driver included with Cura isn't right for your hardware then that is likely the problem. Do a internet search for "USB to SERIAL" port drivers and you should come up with something that will work. My laptop is a couple of months old and has the 3.0 USB ports and I haven't had a problem.
The "USB Printing" plugin isn't maintained as no UM printers use it and no contributors/collaborators have attempted to try and bring it up to date/fix it. A main reason is what you are running into and that is the ridiculous amount of hardware and driver combinations out there both in the computers and in the printers. Printing via the cloud or Octoprint seems to be much preferred (I'm an SD card guy). For the most part - if USB Printing works that's great. If it doesn't then it doesn't.
