Reprinting will come back in firmware version 8.1.2. I expect it will be released within a week.

Wow, that was a detailed reply.
My satisfaction with the printer is increasing rapidly.
We are using the S5Pro for 2 years now. There have been a lot of annoyances with the machine, but now it's getting really interesting.

First print after the firmware upgrade:

A lot of material in a place where it shouldn't be - see photos attached. The build plate was shifted to the right side by about 30 mm.
I don't know if this is related to the new software, but we never had something like that before.

btw: I think you definitely deserve a "design for environment award". The whole print core is scrap with the cables baked into PLA.

    Sorry - I moved this to a different thread as it seems mostly off topic.  You can extract the parts related to the firmware update and post again over there if you want.


    I also changed the title to "head flood" which is what this is called.


    So these are kind of common.  People eventually learn to never have them but it's a nasty lesson to learn.  I've never had one and they can happen in UM3/S3/S5 (but are protected better against in the S7).  I have 2 of those machines and they are pretty active.


    So there are two causes - one is the door on the print head flops down overly easily during a print.  This is pretty rare.


    The much more common cause is that your print came loose at a moment when it was wider than tall (like a hockey puck) and the print head started sliding the print around on the print bed (like a hockey puck).  The filament keeps coming out and builds up and after maybe 15 minutes it starts getting into the head and after an hour or so it's a disaster.  As you now know.


    The solution is to never ever let your parts come loose.  There is a ton of discussion about this.  It also helps to monitor the printer every hour or so but that's not a reasonable solution.  For more details on this (not letting your part come loose) please ask - but first tell me your material that you are printing.


    No need to throw anything away - this is fixable with heat gun and metal tools (like needle nose pliers) but is a royal pain and you have to dedicate an hour or so with the right tools.  Also manually heat up the cores to start melting from the center as well. 


    Or you could possibly send it back to your reseller and make them do it (I know someone who has fixed a dozen of these).  But they will charge of course.


    The most delicate parts are the cables in the cores that go to the sensor and heater but cores are considered "consumables" anyway.  Clean those up last as it's helpful to have the internal heaters.

      • UltiMaker Cura 5.3 stable released
        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!

      • Here it is. The new UltiMaker S7
        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.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        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.
