Nozzle remaining on print at the end of the print

Oh!  I saw this a year or 2 ago.  Haven't seen it for a while.  What version firmware on UM2go and what version of cura are you using?  I forget what causes this.

    One possible cause is if you mess with the flow.  Did you set the flow on your printer to anything other than 100%?  If so there is this bug in the Marlin firmware on the um2go - it's internally translating all the E values so it might get E1000 and if flow is 90% then ever since E was zero then it does E900 but if you changed flow part way through it has to do even more math.


    At the very end it does a *relative* move I think in the gcode and it retracts.  But it gets confused and thinks it's at say E900 when it's really at E1000 and it retracts (or unretracts) like 100mm of filament.  Or it tries to.  And this takes a few seconds.  And it melts a big hold in the print.

    If this is a new printer for you or if you updated the firmware in the last 6 months then you can try "reset to factory settings".  It fixes a whole ton of things when you do that but you will have to level the bed after.  Also if you adjusted the filament settings then those changes you made will get lost.  But "reset to factory settings" is pretty harmless other than that.  On many firmware installs you don't have a choice.


    Also I recommend tinker firmware (which will also require a reset to factory settings after).  If you haven't been messing with extrusion rates/flow rates on your printer then that's probably your best next step:



    I have tinkermarlin on all 3 of my um2go printers.


    I don't use Cura 4.6 yet - I'm on 4.0 I think but it's not much different.  I strongly doubt a bug was introduced between 4.0 and 4.6.

      • 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!
          • Thanks

      • 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.
