Resuming to print at a specific point after a pause
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.
The time on the screen is probably wrong. I'd just continue the print and it should be fine. There's probably a bug with the time calculation if you pause the print. No big deal.
If you aborted the print already then yes it should be possible. Keep the bed hot! If the bed cooled then your part is probably no longer sticking to the bed and it's too late.
I don't know the start up procedure on the UM2+C. On the UM2 it does a nozzle purge which involves touching the print bed in the front left corner. If this should hit your print then you can't continue the print. On the S3/S5/S7 printers you are out of luck because they do active leveling. But on the UM2+C I think you can do it.
Take your existing gcode file (is it a UFP? If so rename it to zip and extract the gcode file, edit and put it back in and rename back to ufp) and edit it. There are instructions on the forum of what to do. There are 2 steps:
1) Remove all the layers you don't want. Easy - there are comments in there - any line in the gcode with "E" in the name involves extruding so make sure any extruding is done well above your failure point. The tricky part is to find where it failed and you can do that with a micrometer or with trial and error.
2) reset the E value. Read about the G92 gcode. You want to fool the printer thinking it has already extruded the exact right amount of filament and use G92 to reset E to the correct value e.g. 1234mm of filament. Google G92 and "resuming" on this forum and you should be able to find it: google this:

Lot's of notes on resuming a failed print.
