Manually extrude through LCD menu

Recommended Posts

Posted · Manually extrude through LCD menu



I am working with an Ultimaker S3 and I wonder whether there is a way to force the extrusion of some material via the LCD menus, same as with the load material procedure?


I am working with different print core diameters (0.4 and 0.25) and the procedure for switching print cores will pull back the filament just an inch or so and after changing the core the filament is only moved forward to reach the core without any extrusion. If I have used a different material with the newly inserted core there is enough material remaining in the core to print a few layers with the old material if the print job is only printing a skirt. That's why I think it's necessary to first extruder some material and stop the extrusion by confirmation.


Unfortunately I have tried to get this extrusion by selecting the "Load Material" procedure with the already loaded filament, expecting that the feeder would not try to transport the filament for the length of the bowden tube. The effect was that the material was ground in the feeder and kind of jammed in the print core in way that it could not be pulled out without heating the core (by the cleaning procedure)

    there must be a "move filament" function, but don't ask me where it is placed at the S3.

    On UM3, it is placed in the material/print core menu, nearby the load and unload command.


    The quick and dirty solution to transport the partly retracted material back to the print core is also: open feeder-lever, push filament manually until it stops, close feeder-lever.

    Thanks for the reply, I've found it.

    That is the place.


    If anybody else missed it:

    In the Material/Print Core menu select the material




    In the Material menu select the context menu by the dots in the upper right corner




    In the  context menu use the "Move" button




    to open the Move Material menu

      • 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.
